Hi I don't know how to do this question

Mathematics
1 answer:
AveGali [126]2 years ago
8 0

Answer:

7 (option B)

Step-by-step explanation:

the area of a trapezoid can be found using the formula:

A = \frac{a+b}{2}h

where

A: area

a: base

b: other base

h: height

here, we can plug in our known variables to solve for h (height)

A: 119

a: 10

b: 24

h: ??

A = \frac{a+b}{2}h

119 = \frac{10+24}{2}h

{now, simplify!}

119 = \frac{10+24}{2}h         {add 10 + 24}

119 = \frac{34}{2}h            {divide 34 by 2}

119 = 17 · h

119     =    17 · h

÷ 17       ÷17             {divide both sides by 17to isolate h}

7 = h

So, the height (h) of this trapezoid is 7

hope this helps! have a lovely day :)

For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in
Shalnov [3]

Answer:

3, in both a), b)

Step-by-step explanation:

a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.

Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is p'(x)=3x^2-9. In particular, the value we are looking for is p'(2)=3(2^2)-9=12-9=3.

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get y=3(x-2)-10=3x-16

b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to p'(2)=3.

What valie of x makes the equation true​
Arada [10]

Answer:

x = 1.25

Step-by-step explanation:

-3x+10 = 5x-8

+3x        +3x

10 = 8x - 8

+8           +8

18 = 8x

x = 18/8

x = 1 1/4 = 1.25

3.2y-1.4y+y-0.6y=0.55
Kazeer [188]

Answer:

it is y=0.25

Step-by-step explanation:

because Step 1: Simplify both sides of the equation.

3.2y−1.4y+y−0.6y=0.55

3.2y+−1.4y+y+−0.6y=0.55

(3.2y+−1.4y+y+−0.6y)=0.55(Combine Like Terms)

2.2y=0.55

2.2y=0.55

Step 2: Divide both sides by 2.2.

2.2y

2.2

=

0.55

2.2
