dezoksy [38]

Answer:

$10,922\frac{2}{3}\ mm^{3}$

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

where

b is the length side of the base

h is the height of the pyramid

In this problem we have

$b=32\ mm$

$h=32\ mm$

substitute

$V=\frac{1}{3}(32^{2})(32)=(32,768/3)\ mm^{3}$

Convert to mixed number

$\frac{32,768}{3}=\frac{32,766}{3} +\frac{2}{3} =10,922\frac{2}{3}\ mm^{3}$

Is y proportional to x and y? Why or why not

nlexa [21]

Answer:

X is directly proportional to y means the value of x is dependent on the value of y. y may not be dependent on x in this case.

Y is directly proportional to x means the value of y is dependent on the value of x. Same as above, in this case, the value of x may not depend on y.

Please help me with these please.

6. Answer: y = 5x - 11

<u>Step-by-step explanation:</u>

Parallel means "same slope". y = 5x - 2 is in the form y = mx + b,

so the slope (m) = 5

Next, input the point (x₁, y₁ = 2, -1) and slope (m = 5) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - (-1) = 5(x - 2)

y + 1 = 5x - 10

y = 5x - 11

7. Answer: $\bold{y = \dfrac{1}{3}x + 4}$

<u>Step-by-step explanation:</u>

Perpendicular means "opposite reciprocal slope". y = -3x + 7 is in the form y = mx + b, so slope (m) = -3 ⇒ m⊥ = $\frac{1}{3}$

Next, input the point (x₁, y₁ = 3, 5) and slope (m = $\frac{1}{3}$ ) into the Point-Slope formula:

y - y₁ = m(x - x₁)

$y - 5=\dfrac{1}{3}(x - 3)$

$y - 5 =\dfrac{1}{3}x - 1$

$y=\dfrac{1}{3}x + 4$
