Answer:

see explanation

Step-by-step explanation:

Given that t and w vary inversely then the equation relating them is

t = $\frac{k}{w}$ ← k is the constant of variation

To find k use the condition t = $\frac{1}{5}$ when w = 4

k = tw = $\frac{1}{5}$ × 4 = $\frac{4}{5}$

t = $\frac{4}{5w}$ ← equation of variation

When w = 9, then

t = $\frac{4}{5(9)}$ = $\frac{4}{45}$

X3(2x2 + 3x) a. 2x5 + 3x4 b. 5x9 c. 2x6 + 3x3 d. 5x

Serhud [2]

Answer:

$2x^5+3x^4$

Step-by-step explanation:

$x^3\left(2x^2+3x\right)$

Apply distributive law: $a\left(b+c\right)=ab+ac$

$x^3\left(2x^2+3x\right)=x^3\times \:2x^2+x^3\times \:3x$

$x^3\times \:2x^2+x^3\times \:3x$

$2x^5+3x^4$

Find the area and perimeter. Stuck on this one need help

masya89 [10]

9514 1404 393

Answer:

area: 114 square units
perimeter: 44 units

Step-by-step explanation:

The figure is a trapezoid with bases 12 and 7, and a height of 12. The area formula is ...

A = (1/2)(b1 +b2)h

A = (1/2)(12 +7)(12) = 114 . . . square units area

The length of side AB can be found using the distance formula:

d = √((x2 -x1)^2 +(y2 -y1)^2)

d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13

The sum of the side lengths is then ...

13 +7 +12 +12 = 44 . . . units perimeter
