What is the area. Also if you can explain that would be great. ​

Answers

Answer:

11m^2

Step-by-step explanation:

So first it would probably help to split it into different shapes. then you find the area of those shapes and add them.  

36 + 45 + 30 = 111 m^2

The area would be 111m^2.
First I broke the figure into three pieces and I did 12x5 which is 60, then 10x3 which is 30. Add them together and get 90. Lastly, 7x3 is 21 so add 21+90 and this gets you the area of 111m.

An inequality is shown below.
-7x > 63

Which inequality represents the solution set?

a. x > 9
b. x > 70
c. x < –9
d. x < –70

Answers

Answer: The answer is d

Step-by-step explanation: This is because a, would have the answer as -63 b would make the answer be -490, and c would have below 63 because -7 x -9 = 63 but if x is below -9 then it would be to low. Lastly for D since a negative times a negative is a positive then you can ignore the negative symbols and just substitute x for 70 and -7 for 7 then multiply. 7 x 70 = 490 which matches the inequality because it is more than 63.

A ball is thrown from an initial height of 6 feet with an initial upward velocity of 17 ft/s. The ball's height h (in feet) after t seconds is given by the following.


h=6+17t-16t^2


Find all values of t for which the ball's height is 10 feet.


Round your answer(s) to the nearest hundredth.
(If there is more than one answer, use the "or" button.)
t=___seconds

Answers

Answer:

6 + 29t - 16t^2 = 18

16t^2 - 29t + 12 = 0

t = (29 +- √(29^2 - 4*12*16))/32

t = (29 +- √73)/32

t  = 0.639249882958827, 1.1732501170411

Step-by-step explanation:

The values of t for which the ball's height is 10 feet are approximately 0.71 seconds or 0.35 seconds

The given equation for the height of the ball is a quadratic equation, which is solved using the quadratic formula to find the values of t.

The quadrature formula for ax² + bx + c = 0 is:

[tex]x = \frac{-b \pm \sqrt{(b^2- 4ac)}}{2a}[/tex]

Given that,

The initial height of the ball: 6 feet

The initial upward velocity of the ball: 17 ft/s

The equation for the ball's height after t seconds: h = 6 + 17t - 16t²

The goal is to find the values of t for which the ball's height is 10 feet.

To find the values of t when the ball's height is 10 feet,

Set the equation h = 10 and solve for t.

Plugging in the given equation h = 6 + 17t - 16t²

And substituting h with 10, we get:

10 = 6 + 17t - 16t²

Rearrange the equation to solve for t.

16t² - 17t + 4 = 0

To find the values of t, we can use the quadratic formula:

In this case,

a = 16,

b = -17, and

c = 4.

Plugging these values into the quadratic formula, we get:

[tex]t = \frac{17 \pm \sqrt{((-17)^2- 4 \times 16 \times 4)}}{2 \times 16}[/tex]

Simplifying this equation, we have:

[tex]t = \frac{(17 \pm \sqrt{(289 - 256)}}{32}[/tex]

[tex]t = \frac{(17 \pm \sqrt{33})}{32}[/tex]

t ≈ 0.710 or 0.351

Hence,

Rounding to the nearest hundredth, we get two possible values for t:

t ≈ 0.71 seconds or 0.35 seconds

For this shape there are four points. The plotted ordered pairs are:
M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)

All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.

M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)

(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.
