Would you please help me to solve this 9.1x10^-5)^-4

[( 91 * 10^-1 ) *10^ -5]^-4 = (91 * 10^-6)^-4 = 91^-4 * 10^24 = ( 10^24 )/ ( 91^4 ) =

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Consider the equation below.

y=3x^2+30x+71

y=3(x+__)^2+__

Use completing the square to rewrite the given equation and reveal the extreme value.

The extreme value of the equation is at (__ ,__ )

(the ___ are blanks where the answers are supposed to be)

If , then

. So, in the first gap you can write 5 and in the second you can write -4.

Since , the minimum value of y is when . The solution of the last equation is x=-5 and then y=-4 -- these are numbers, which you can write in the third and fourth gaps.

5/12(x-5)=30

Can you please show the steps to the answer?

Multiply both sides by 12

12*5/12(x-5)=30*12

5(x-5)=360

5x-25=360 then add 25 to both sides

25+5x-25=360+25

5x=385 then divide both sides by 5

5x/5=385/5

X=77

Hope this helps!

12*5/12(x-5)=30*12

5(x-5)=360

5x-25=360 then add 25 to both sides

25+5x-25=360+25

5x=385 then divide both sides by 5

5x/5=385/5

X=77

Hope this helps!

Find the savings plan balance after 1 year with an APR of 13% and monthly payments of $100. Assume an ordinary annuity.

Check the formula of future value of annuity ordinary (through Google)

FVOA=100[((1+0.13/12)^(12)-1/(0.13/12)]

FVOA=1274.15

FVOA=100[((1+0.13/12)^(12)-1/(0.13/12)]

FVOA=1274.15

1. Joshua has a ladder that is 17 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 16.5 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 70°. Will the ladder be safe at this height? Show your work please. Help please???

Answer:

No

Step-by-step explanation:

It is given that Joshua has a ladder that is 17 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 16.5 ft above the ground. Thus,

Use Sine function , we have

Substituting the given values, we have

Height represents the height of wall.

So the ladder will only reach maximum height of 15.98 ft , just short of 0.52 ft. at the maximum angle of 70 degrees.

Hence, The ladder will not be safe for 16.5 ft height of wall.

Answer:

The question is asking to solve a problem that'll "add up", or in other words, makes sense; through the use of Trigonometric functions. The leaning ladder is the hypotenuse of 17ft, adjacent to that is a wall that measures 16.5ft above the ground. The angle both sides make must be more than, 70°.

Thus, the ladder will not be safe for its height and therefore won't make sense.
