Answer:

For question 26 the answer is ( 9^210 )

For question 27 the answer is ( 24 )

Step-by-step explanation:

For question number 26: try on the scientific calculator the equation you have pictured it will give you a very long number beginning with 《 2459953978》

Then put the the 9^210 on the calculator and click ( =) if it didn't work try clicking S》D then you will get the same long number Count at least the first 6 numbers for assurance

For question number 27 :The volume of a right cone is given by 

 $v = \frac{1}{3} \pi \ \: {r}^{2} h$ 

 Here, you only know the value of one of the variables, V, so you'll need to use the information in the question to somehow write r and h in terms

If the cone is three times as wide at the base as it is tall, then call the diameter 3x and the height of the cone one-third of that, or x. The volume formula calls for the radius, which is half the diameter, or

 $\frac{3x}{2}$ 

Substitute these values into the formula and solve for x:

$384\pi = \frac{1}{3} \pi {( \frac{3}{2}\pi) }^{2} x \\ 384 = ( \frac{1}{3} )( \frac{9}{4} {x}^{2} )x \\ 384 = \frac{3}{4} {x}^{3 } \\ 512 = {x}^{3 } \\ \sqrt[3]{512} = x \\ 8 = x \\$

The question asks for the diameter of the base, which is 3x = 3(8) = 24.

Use the formula A = Pe^r*t. How much money would you have if you invested $6000 for 5 years, compounded continuously, at a rate

sergey [27]

Hi there :-)

The answer is

A=6,000×e^(0.09×5)
A=9,409.87

Hope it helps

HELP DUE IN 15 MINS! x =??

Bas_tet [7]

Answer:

Step-by-step explanation:

x = 1/2 ( arc(SF) + arc(RQ))

ARC SF = 50

Arc RQ (the large one ) = 200

Large Arc RQ = 200

Arc SF = 50

x = 1/2 (50 + 200)

x = 1/2 250

x = 125

8. what is the graph of the inequality in the coordinate plane? y<-2

LekaFEV [45]

1) Draw the coordinate plane

2) Draw the line y = - 2

It is a line parallel to the y axis, two units below the origin

3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.
