A object falls at 16t^2 feet in t seconds you drop a rock from a bridge that is 906 what is the hight in feet after the rock is droped
Answer:
824 feet
Step-by-step explanation:
Given
[tex]h(t) = 16t^2[/tex]
[tex]H = 906[/tex] -- Initial Height
Required
Calculate the height after 2 seconds --- missing from the question
First, we calculate the distance moved in 2 seconds
[tex]h(t) = 16t^2[/tex]
[tex]h(2) = 16*2^2[/tex]
[tex]h(2) = 16*4[/tex]
[tex]h(2) = 64[/tex]
This means that the object covered 64feet
The object current height is then calculated as:
[tex]Height = H - h(t)[/tex]
t = 2. So, the equation becomes
[tex]Height = H - h(2)[/tex]
Substitute values for H and h(2)
[tex]Height = 906- 64[/tex]
[tex]Height = 824[/tex]
factor out the gcf 12y³+10y²
Answer:
Find the prime factors of each term in order to find the greatest common factor (GCF).
2y^2
Factoring out the greatest common factor (GCF)To factor the GCF out of a polynomial, we do the following: Find the GCF of all the terms in the polynomial. Express each term as a product of the GCF and another factor. Use the distributive property to factor out the GCF.

Examine the following graph of a nonlinear function.

What is the average rate of change over the interval 1≤x≤3?
Enter your answer as a number, like this: 42
Answer:
the answer is 3
Step-by-step explanation:
just guessed and got it right since it wasn't 1 or 2 because i tried searching up the answer and they were around 2 but rlly close to 3
The rate of change of y with respect to x is 3.
We have a graph of a Non - linear function.
We have to determine the average rate of change over the interval
1 ≤ x ≤ 3.
What do you understand by the Average rate of change of two quantities plotted along X and Y axis respectively?It indicates the rate of change of y with respect to x. Mathematically -
[tex]$r=\frac{dy}{dx}[/tex]
or
[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]
According to the question -
The coordinate points plotted area s follows -
X Y
1 -2
2 0
3 4
Now, the average rate of change →
[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]
[tex]$r =\frac{4-(-2)}{3-1}[/tex]
r = 3
Hence, the rate of change of y with respect to x is 3.

It is similar because the order of operations is the same for fractions and for whole numbers.
It is different because when you add or subtract fractions, you need a common denominator. When you deal with whole numbers, there are no denominators.

Write the equation in standard form for the circle passing through (2,6) centered at the origin.
==========================================================
Explanation:
The center is the origin, so (h,k) = (0,0).
The point (x,y) = (2,6) is on the circle's edge. We'll use these four values to find the value of r^2
(x-h)^2 + (y-k)^2 = r^2
(2-0)^2 + (6-0)^2 = r^2
2^2 + 6^2 = r^2
4 + 36 = r^2
40 = r^2
r^2 = 40
We don't need to solve for r itself. If you wanted to, you'd get the radius to be r = sqrt(40) = 2*sqrt(10) = 6.324555 approximately.
------------------
Since h = 0, k = 0, and r^2 = 40, we can say:
(x-h)^2 + (y-k)^2 = r^2
(x-0)^2 + (y-0)^2 = 40
x^2 + y^2 = 40
if the perimeter of Triangle XYZ is 56 cm, what is the perimeter of Triangle ABC?
Answer:
28 cm
Step-by-step explanation:
Triangle ABC is obtained by joining the mid points of the sides of triangle XYZ.
So, perimeter of triangle ABC will be equal to half of the perimeter of triangle XYZ.
[tex] P(\triangle ABC) = \frac{1}{2} \times P(\triangle XYZ) [/tex]
[tex] P(\triangle ABC) = \frac{1}{2} \times 56 [/tex]
[tex] P(\triangle ABC) = 28\: cm [/tex]

Answer:
2[tex]x^{2}[/tex] + 9x - 5 = 0
Step-by-step explanation:
// Use the Vijet's theorem,
// note that the kofficient before [tex]x^{2}[/tex] = 1
Sum of the roots is:
1/2 + (-5) = - 4,5
Product of the roots is:
0,5 * (-5) = - 2,5
Formation of quadratic equation:
[tex]x^{2}[/tex] - (sum of the roots) x + product of the roots = 0
[tex]x^{2}[/tex] - (-4,5) * x + (-2,5) = 0
[tex]x^{2}[/tex] + 4,5x -2,5 = 0
// multiply both sides by 2
2[tex]x^{2}[/tex] + 9x - 5 = 0

Grace made a dot plot showing the distances she ran each day for two weeks.
She says that she usually runs 7 miles each day because that is the distance that occurs most often.
Do you agree with Grace’s reasoning?

Dot plot named as ALTDCDistances RunALTDC has number line from 1 to 7. 1 dot on 1, 3 dots on 2, 3 dots on 3, 3 dots on 4 and 4 dots on 7 are given.
The mode, which is (3,4, or 7) ,(is or is not) a typical distance for the data. The median, which is (3.5,4, or 7),(is or is not) a typical distance for the data. The mean, which is (3,4, or 7) ,(is or is not) a typical distance for the data. So, Grace’s reasoning(is or is not ) correct.
Answer:
The mode, which is 7, is not a typical distance for the data. The median, which is 3.5, is not a typical distance for the data. The mean, which is 4, is a typical distance for the data. So, Grace’s reasoning is not correct.

Sung loo worked 54 hours during a special sale at the store. 10 hours was time and a half, and 4 hours were at double time. Her regular rate is $6.86. How much would Sung Loo make?
Answer:
$432.18
Step-by-step explanation:
Time and a half = 50% more pay rate / 1.5*6.86 = $10.29 per hour
Double time = 2*6.86 = $13.72 per hour
Rest of the time => At regular rate
Total Amount = 10(10.29) + 4(13.72) + (54 - 10 - 4)(6.86)
= 10(10.29) + 4(13.72) + (40)(6.86)
= $ 432.18
Answer:
so 10 hours was 1,5 time and 4 hours was 2 (double) time Her regular rate is $6,86/h so 10 h with 1,5 time make 10*1,5 = ? and 4 h with 2 time make 4*2 = ? total how much you get multiplie by 6,86 and will get in this way easy sure the correct answer.
Among two supplementary angles the measure of the larger angle is 400 more than the
measure of the smaller. Find their measures.
9514 1404 393
Answer:
70° and 110°
Step-by-step explanation:
The sum of angles is 180°; their difference is 40°. So, the larger is ...
(180° +40°)/2 = 110°
The smaller is 180° -110° = 70°
The two angles are 70° and 110°.
_____
Above, we have "cut to the chase." If you let the larger be 'a' and 's' and 'd' represent the sum and difference, you have ...
a + (a-d) = s . . . . the sum of the larger and smaller angles
2a = s+d . . . . . . add d
a = (s+d)/2 . . . . the relation we used.
