The formula for the surface area S of a cone is S = 2+ats where r is the radius and s is the slant height. Solve the formula for

s. Justify each step. Then find the slant height of the cone when the surface area is 220 square feet and the radius is 7 feet. Approximate to the nearest tenth.

What is the solution to −1/4(d+1)<2

kogti [31]

Answer:

$d > -9$

Step-by-step explanation:

$-\dfrac{1}{4}(d + 1) < 2$

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

$-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)$

$d + 1 > -8$

Subtract 1 from both sides.

$d + 1 - 1 > -8 - 1$

$d > -9$

I need algebra help.....

Lubov Fominskaja [6]

Answer:

$y=4(3)^x$

Step-by-step explanation:

From the table given in the question,

x y Difference Ratio

1 12 - -

2 36 36-12 = 24 $\frac{36}{12}=3$

3 108 108-36 = 72 $\frac{108}{36}=3$

4 324 324-108 = 216 $\frac{324}{108}=3$

5 972 972-324 = 648 $\frac{648}{216}=3$

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

$y=a(b)^x$

For a point $(1, 12),$

$12=a(b)^1$

$ab=12$ ------(1)

For another point of the table $(2,36)$ ,

$36=a(b)^2$

$ab^2=36$ --------(2)

Equation (2) divided by equation (1)

$\frac{ab^2}{ab}=\frac{36}{12}$

$b=3$

From equation (1),

$3a=12$

$a=4$

Therefore, exponential function will be,

$y=4(3)^x$
