$\bf \textit{lateral area of a cylinder}\\\\ LA=2\pi rh~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=4\\ h=5 \end{cases}\implies LA=2\pi (4)(5)\implies V=40\pi$

Answer:

Step-by-step explanation:

This is a negative slope since it is going from left to right so that leaves you with c or d.

The slope is rise over run so in this case the rise is 1 and the run is -3 since its going left.

This leads you to -1/3

Hope this helped :)

HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.

Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4

RV = 4 , RU = 1.5 AND UV = 2.7

∴ RT/RV = 8/4 = 2

AND RS/RU = 3/1.5 = 2

AND ST/UV = 5.4/2.7 = 2

∴Δ RTS IS SIMILAR TO ΔRVU

SO, the best statement is:

Each pair of sides corresponds with a common ratio of 2.

A thermometer gives a reading of 26 degrees Celsius. Use the formula c =5/9(f-32). Write the inverse function and use it to find

guajiro [1.7K]

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

$C = \frac{5}{9} (F - 32)$

Multiply both sides by 9

$9C = \frac{5(9)}{9} (F - 32)$

Simplify

$9C = 5(F - 32)$

Divide both sides by 5

$\frac{9}{5} C = \frac{5}{5} (F - 32)$

Simplify

$\frac{9}{5} C = F -32$

Add 32 in both sides

$\frac{9}{5} C + 32 = F - 32 + 32$

Simplify (Inverse)

$\frac{9}{5} C + 32 = F$

Substitute to find F

$\frac{9}{5} (26) + 32 = F$

Simplify

F = 46.8 + 32

Result

F = 78.8

Choose the fractions that are greater than 1/2.

Gennadij [26K]

5/8
6/3
7/10
These are all the answers 4/8 is 1/2 and 5/8 is over it there is no half of 3 but 6/3 is 2 and 2 is a whole number it's over 1/2
5/10=1/2 and 7/10 is over it 1/4 isn't an answer because 2/4=1/2 6/12=1/2 but it says over 1/2 and finally 5/12 isn't it because like I said above 6/12 is 1/2

Which is f(-1) for the function f(x)= 3x^2+9

blsea [12.9K]

Answer:

C. f(-1) =12

Step-by-step explanation:

f(x)= 3x^2+9

Let x=-1

f(-1) = 3(-1)^2 +9

= 3(1)+9

= 3+9

= 12

f(-1) =12
