Answer:
-14 or -28
Step-by-step explanation:
2x-8=-16
4x-3=-12
-16-12=28
-16-(-12)=-14
(i would go with -14)Can someone help me find the solution to these equations by using substitution
A fossilized leaf contains 8% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as the half-life of carbon 14.
Answer:
Step-by-step explanation:
0.5^(t/5600) = 0.08
2^(-t/5600) = 0.08
-t/5600 = log₂0.08
t = -5600 log₂0.08 ≈ 20406 years

Solve the equation: 2/3x+1/4=3
Answer:
x = 33/8
Step-by-step explanation:
2/3 x + 1/4 = 3
Subtract 1/4 from both sides.
2/3 x = 3 - 1/4
2/3 x = 12/4 - 1/4
2/3 x = 11/4
Multiply both sides by 3/2.
3/2 * 2/3 x = 3/2 * 11/4
x = 33/8

Given the function, where a, b, and c are positive numbers:
f(x) = (x - a)(x - b)2(x2 + c)
How many real roots does f(x) have, including multiple roots? |
How many imaginary roots does f(x) have?
Answer:
2 real roots and 1 imaginary roots
Step-by-step explanation:
f(x) = [tex](x-a)(x-b)^{2} (x^{2}+c)[/tex]
There are only 2 real roots and one imaginary roots.
Separate the equation into sections because the function is a multiplication with no outside sum or substraction:
Real Roots:
[tex](x-a)[/tex] = 0 when x = a
[tex](x-b)^{2}[/tex] = 0 when x = b
Imaginary roots:
[tex](x^{2}-c)[/tex] = 0 when x = [tex]\sqrt{-c}[/tex]

The function h(t)=-16t^+144 represents the height, h(t), in feet of an object from the ground at t seconds after it is dropped. A realistic domain for this function is?
Answer:
[tex]0 \le t \le 3[/tex]
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 144[/tex]
Required
Determine a reasonable domain
The domain is the possible values of t for which h(t) is true
Before the object is released, the value of t is:
[tex]t = 0[/tex]
Next, is to calculate the value of t after the ball reaches the ground.
At this point, h = 0.
So, we have:
[tex]h(t) = -16t^2 + 144[/tex]
[tex]0 = -16t^2 + 144[/tex]
[tex]16t^2 = 144[/tex]
Divide both sides by 16
[tex]t^2 = 9[/tex]
Take the positive square root of both sides
[tex]t = 3[/tex]
This means that the ball reaches the ground in 3 seconds.
So, the domain is:
[tex]0 \le t \le 3[/tex]

How do you solve for an area of a circle?
Answer:
Identify the radius of a circle. The radius is the length from the center of a circle to the edge of the circle. You can measure this in any direction and the radius will be the same. The radius is also one half of the diameter of a circle. The diameter is the line segment that passes through the center and connects opposite sides of the circle.[1]
The radius will generally be provided to you. It can be difficult to measure to the exact center of a circle, unless the center is already marked for you on a circle drawn on paper.
For this example, assume that you are told that the radius of a given circle is 6 cm.
well the formula for the area of a circle is A =[tex]\pi r^2[/tex]
r is for the radius
which is half the size or number of the diameter
so ex. lets say that the diameter of a circle is 10, so that makes the radius 5
A = [tex]\pi[/tex] [tex]5^2[/tex]
A = [tex]\pi * 25[/tex]
A = 78.54
Ta -Da!!
Note: sometimes is the test ask you to replace [tex]\pi[/tex] for 3.14, it would still work
Jon is hitting baseballs. The height of the ball is given by h(t) = - 16t? + 5t + 5 where t is in
seconds. When will the baseball hit the ground?
Your equation is wrong. See below for correct equation.
The ball will hit the ground when h(t) is 0.
Here is the set up:
0 = -16t^2 + 5t + 5
Solve for t to find your answer.

A biologist estimates that the human body contains 90 pounds of water for every 100 pounds of body weight. At the rate estimate the number of pounds of water in a child who weighs 80 pounds
Answer:
72 lb
Step-by-step explanation:
Write and solve an equation of ratios:
80 pounds x
----------------- = ------------------
100 pounds 90 pounds
Cross multiplying, we get (100 pounds)x = 7200, or x = 72 pounds.
The 80 pound child's weight includes 72 pounds of water.

Answer:
Step-by-step explanation:
To compare fractions, they need to have a common denominator.
The least common denominator of 1/2 and 2/3 is 6.
1/2 = 3/6
2/3 = 4/6
Now find the fraction with the larger numerator.
4/6 > 3/6, so 2/3 > 1/2

Actually Welcome to the Concept of the Isosceles triangles.
Since, the sides are equal, we can equate them, so we get as,
==> 16x + 13 = 24x -19
=> 24x -16x = 13+19
=> 8x = 32
x = 4
hence ==> x = 4.

Answer:
9m×7m:10m-2m paràllelogram
Answer:
A = 70 m²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 7 , then
A = 10 × 7 = 70 m²
Which expressions are equivalent to g + h + (j + k)? Check all that apply.
g + (h + j) + k
(g + h) + j k
(g + h) + j + k
g + (h j) + k
g h + j k
g (h + j) k
g + h (j + k)
Answer:
According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.
