If a varies directly as b, and a = 28 when b = 7, find b when a = 5.

Reika [66]

Answer: Option B.

$b=\frac{5}{4}$

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

$a = kb$

We know that when a = 28 then b = 7. So

$28 = k * 7$

$k=\frac{28}{7}$

$k=4$

Therefore the equation of proportionality is:

$a=4b$

So when $a=5$ then:

$5=4b\\\\b=\frac{5}{4}$

Which is equivalent to (4 x y minus 3 z) squared, and what type of special product is it?

Yuliya22 [10]

Answer:

$16x^{2}y^{2}-24xyz+9z^2$

It is a perfect square trinomial.

Step-by-step explanation:

The square of a binomial can be solved like this:

$(a+b)^2=a^2+2ab+b^2$

We have the expression:

$(4xy-3z)^2$

Then, we consider a and b as:

$a=4xy\\ b=-3z$

The solution would be:

$a^2=(4xy)^2=4^2x^2y^2=16x^2y^2$

$b^2=(-3z)^2=(-3)^2z^2=9z^2$

$2ab=2(4xy)(-3z)=-24xyz$

$(4xy-3z)^2=16x^2y^2-24xyz+9z^2$

The volume of a rectangular prism can be computed using the formula v = lwh. what is the length of a prism that has a volume of

OLEGan [10]

We are given the formula:

V = l w h

and the following values:

l = ?

V = 1344 cm^3

w = 8 cm

h = 12 cm

SO rewriting the formula in terms of l:

l = V / w h

l = 1344 cm^3 / (8 cm * 12 cm)

l = 14 cm

Answer:

d
