The quadratics that would not have 5 and -7 as zeros are (1) and (3)
Identifying the quadratics that would not have 5 and -7 as zeros?From the question, we have the following parameters that can be used in our computation:
Zeros: 5 and -7
This means that
x = 5 and x = -7
Rewrite as
x - 5 = 0 and x + 7 = 0
Multiply both equation
This gives
(x - 5)(x + 7) = 0
Rewrite as
f(x) = (x - 5)(x + 7)
When expanded, we have
f(x) = x² + 2x - 35
So, we have
(2) f(x) = x² + 2x - 35
(4) f(x) = 2(x + 7)(x - 5)
Hence, the quadratics that would not have 5 and -7 as zeros are (1) and (3)

What is the area of the triangle?
Answer:
60
Step-by-step explanation:
Area of a triangle: 1/2(bh)
Base = 12
Height = 10
1/2(12*10)
1/2(120) = 60
There's a roughly linear relationship between the length of someone's
femur (the long leg-bone in your thigh) and their expected height.
Within a certain population, this relationship can be expressed using
the formula h = 2. 46f + 60. 6, where h represents the expected
height in centimeters and f represents the length of the femur in
centimeters. What is the meaning of the f-value when h 128?
This means that in the population represented by the formula, someone with a femur length of 27.4 centimeters would be expected to have a height of 128 centimeters
When h is 128, we can use the formula h = 2.46f + 60.6 to solve for the corresponding value of f.
128 = 2.46f + 60.6
Subtracting 60.6 from both sides:
67.4 = 2.46f
Dividing both sides by 2.46:
f ≈ 27.4
Therefore, when h is 128, the f-value (length of the femur) is approximately 27.4 centimeters. This means that in the population represented by the formula, someone with a femur length of 27.4 centimeters would be expected to have a height of 128 centimeters.

An airplane is approaching Seattle International Airport. The pilot begins a 13 degree angle of d scent starting from a height of 500 feet. How far from the airport is the plane? Round to the nearest tenth.
We get that the plane is about 2193.0 feet from the airport, Rounding to the nearest tenth
To solve the problem, we will use trigonometry and the tangent function, which relates the other facet of a right triangle to the adjoining aspect:
tan(theta) = opposite / adjacent
wherein theta is the angle of descent, opposite is the change in height, and adjacent is the space from the airplane to the airport.
Rearranging the formula, we get:
adjacent = contrary / tan(theta)
because the angle of descent is 13 ranges and the alternate in height is from 500 ft, we've got:
contrary = 500 ft
theta = 13 stages
Substituting these values into the formula, we get:
adjacent = 500 ft / tan(13 ranges)
using a calculator, we find that tan(13 stages) is about 0.228, so:
adjacent = 500 feet / 0.228 = 2192.98 feet
Therefore, we get that the plane is about 2193.0 feet from the airport.

Solve the following problems:
given: circle k(o), diameter us, mru=50°, mut=30°
find: m
The measure of angle M is 20°.
To solve the problem, we need to find the measure of angle M, given the information about Circle K with center O, diameter US, angle MRU = 50°, and angle MUT = 30°.
Step 1: Determine the relationship between angles MRU and MUT.
Since MRU and MUT are both inscribed angles in Circle K, they share the same intercepted arc, which is arc MU.
Step 2: Calculate the measure of arc MU.
The measure of an intercepted arc is twice the measure of the inscribed angle. Since angle MRU = 50°, the measure of arc MU will be 2 * 50° = 100°.
Step 3: Find the measure of angle M.
We know that angle MUT = 30°, and the measure of an intercepted arc is twice the measure of the inscribed angle. Therefore, the measure of arc MT = 2 * 30° = 60°. Now, since arc MU = 100°, we can determine the measure of arc MS (arc MS = arc MU - arc MT) which is 100° - 60° = 40°.
Step 4: Calculate the measure of angle M.
Finally, the measure of angle M can be found using the intercepted arc MS. Since the measure of an intercepted arc is twice the measure of the inscribed angle, angle M = 1/2 * arc MS = 1/2 * 40° = 20°.

If arc wvx=(13x+9) and angle wxz=(5x+36) find angle wxy
Angle WXY is vertical to angle WXZ, they are equal, therefore, angle WXY is also 141 degrees.
How to find the angle WXY using information about the arc WVX and angle WXZ in a circle?To find the angle WXY, we need to use the properties of angles formed by intersecting chords in a circle. The angles formed by intersecting chords are related to the arcs intercepted by those chords.
Given that the arc WVX is equal to (13x + 9) and the angle WXZ is equal to (5x + 36), we can set up an equation:
Angle WXZ = [tex]\frac{1}{2}[/tex] * Arc WVX
(5x + 36) = [tex]\frac{1}{2}[/tex] * (13x + 9)
To solve for x, we'll multiply both sides of the equation by 2 to eliminate the fraction:
2(5x + 36) = 13x + 9
10x + 72 = 13x + 9
Subtracting 10x and 9 from both sides, we get:
72 - 9 = 13x - 10x
63 = 3x
Dividing both sides by 3, we find:
x = 21
Now that we have the value of x, we can substitute it back into the equation for the angle WXZ to find its value:
Angle WXZ = 5x + 36 = 5(21) + 36 = 105 + 36 = 141 degrees
Since angle WXY is vertical to angle WXZ, they are equal. Therefore, the angle WXY is also 141 degrees.

In a binomial experiment consisting of five trials, the number of different values that x (the number of successes) can assume is _____
In a binomial experiment consisting of five trials, the number of different values that x (the number of successes) can assume is 6.
A binomial experiment is a statistical experiment that meets four specific conditions: there are a fixed number of trials, each trial is independent of one another, there are only two possible outcomes (success or failure) in each trial, and the probability of success remains constant throughout the trials.
In this case, the binomial experiment consists of five trials, so the possible outcomes for x (the number of successes) can range from 0 successes to all 5 successes. To find the number of different values x can assume, simply add 1 to the total number of trials, as it includes the case of 0 successes.
Therefore, x can take on the following values: 0, 1, 2, 3, 4, or 5. As there are 6 possible values for x, the number of different values that x can assume in a binomial experiment consisting of five trials is 6.

In which quadrant does 0 lie if the following statements are true: cos 0 > and sin> 0
The angle θ lies in Quadrant I given that cos(θ) > 0 and sin(θ) > 0.
Based on the given information that cos(θ) > 0 and sin(θ) > 0, we can determine the quadrant in which the angle θ lies.
Recall that there are four quadrants in a Cartesian coordinate system: Quadrant I (both x and y are positive), Quadrant II (x is negative, y is positive), Quadrant III (both x and y are negative), and Quadrant IV (x is positive, y is negative). The cosine function, cos(θ), represents the x-coordinate of a point on the unit circle, while the sine function, sin(θ), represents the y-coordinate.
Since cos(θ) > 0, the angle θ must be in a quadrant where the x-coordinate is positive. This means that θ can lie in either Quadrant I or Quadrant IV. Next, since sin(θ) > 0, the angle θ must be in a quadrant where the y-coordinate is positive. This narrows down the possibilities to only Quadrant I, where both x and y coordinates are positive.
Therefore, the angle θ lies in Quadrant I given that cos(θ) > 0 and sin(θ) > 0.

Compared with an SRS of 900 8th-graders, the margin of error for a 95% confidence interval for mu is smaller when using an SRS of 1600 8th-graders.
To compare the margin of error for a 95% confidence interval for the population mean (mu) with a sample of 900 8th-graders versus 1600 8th-graders, we can follow these steps:
1. Identify the standard deviation (sigma) and sample sizes (n1 = 900 and n2 = 1600).
2. Calculate the standard error for each sample size:
SE1 = sigma / sqrt(n1) = 125 / sqrt(900) = 125 / 30
SE2 = sigma / sqrt(n2) = 125 / sqrt(1600) = 125 / 40
3. Determine the critical value (z-score) for a 95% confidence interval. In this case, it is 1.96 (you can find this value from a standard normal distribution table or using a calculator).

ME1 = z-score * SE1 = 1.96 * (125 / 30)
ME2 = z-score * SE2 = 1.96 * (125 / 40)
5. Compare the margin of errors:
ME1 is larger than ME2.

Select all the situations that can be modeled with an equation.
please help!!
The situations that can be modeled with an equation include the following:
A. The sale price of a television is $125 off of the original price.
C. Marco spent twice as much as Owen.
E. Ben paid a total of $75 for a shirt and a pair of shoes.
What is an equation?In Mathematics and Geometry, an equation can be defined as a mathematical expression which shows that two (2) or more thing are equal. This ultimately implies that, an equation is composed of two (2) expressions that are connected by an equal sign.
Assuming the variable x represent the independent variable and y represents the dependent variable, we have the following equations;
"The sale price of a television is $125 off of the original price."
y = x - 125
"Marco spent twice as much as Owen."
y = 2x
"Ben paid a total of $75 for a shirt and a pair of shoes."
x + y = 75

1. If Cos A = 1/4, what is Sin B?
2. Simplify Sin A + Cos B ÷ 2
3. If Tan B = 1/5, what is Tan A? Which angle is bigger, angle A or angle B?
Please answer all 3
a. Sin A = opposite/hypotenuse = √15/4
b. (Sin A + Cos B) ÷ 2 = (Sin A + Cos B)/2
c. Tan A = 1/5
The both angle could be of same size
How do we calculate?Since Cos A = adjacent/hypotenuse,
Applying the Pythagorean theorem,
we can find the opposite side:
opposite^2 + 1^2 = 4^2
opposite^2 = 16 - 1
opposite = √15
Now we can find the value of Sin A:
Sin A = opposite/hypotenuse = √15/4
b.
Sin A + Cos B = (Sin A) + (Cos B)
(Sin A + Cos B) ÷ 2 = (Sin A + Cos B)/2
c. Since Tan B = opposite/adjacent,
we use Pythagorean theorem to find the hypotenuse:
hypotenuse^2 = 5^2 + 1^2
hypotenuse = √26
Tan A = opposite/adjacent = 1/5
