Answer:

8 units^2

Step-by-step explanation:

The base of this triangle is 4 units and the height is also 4 units.

The area-of-a-triangle formula is A = (1/2)(base)(height).

Here, that area is A = (1/2)(4 units)(4 units) = 8 units^2

A factory that manufactures basketballs spends $3 on each basketball that it produces.

Iteru [2.4K]

Answer:

C. Neither linear nor non linear

Step-by-step explanation:

The company spends $3 on each basketball it produces, which means if the company produces $b$ basketballs, then the amount $y$ it would have spent is

$y=3b$ .

Now, the rate of cost growth is the rate of change, or the derivative of the amount spent $y$ ; therefore,

$\dfrac{dy}{db} =\dfrac{d(3b)}{db} = 3 \dfrac{db}{db} =3$

which is a constant, which means the rate of cost growth is not increasing. Therefore, rate of cost growth at the factory is neither linear nor nonlinear.

Sophia did push-ups every day for 7 days. Each day after the first day, she did 5 more push-ups than the day before. In total sh

Dafna1 [17]

Answer:

Push- ups on last day = 40

Step-by-step explanation:

According to given conditions:

Let push-ups on:

1st day = x

2nd day = x + 5

3rd day = x + 10

4th day = x + 15

5th day = x + 20

6th day = x + 25

7th day = x + 30

Now total push ups = adding all

x + x + 5 + x + 10 + x + 15 + x + 20 + x+ 25 + 30 + x = 175

By adding same terms:

7x + 105 = 175

Subtracting 105 from both sides

7x + 105 - 105 = 175 - 105

7x = 70

Dividing both sides by 7 we get:

x = 70/7

x = 10

Now calculating push-ups on days:

1st day = x = 10

2nd day = x + 5 = 10 + 5 = 15

3rd day = x + 10 = 10 + 10 = 20

4th day = x + 15 = 10 + 15 = 25

5th day = x + 20 = 10 + 20 = 30

6th day = x + 25 = 10 + 25 = 35

7th day = x + 30 = 10 + 30 = 40

So number of push-ups on 7th (last) day is 40.

I hope it will help you!
