A painter sets a ladder
against a wall 9 ft above
the ground. If the ladder is
3 feet from the base of the
wall, how long is the ladder?
Round your answer
to the nearest tenth.
Answers
Answer: About 10 ft.
Use Pythagorean's Theorem!
c=[tex]\sqrt{9^2+3^2}[/tex]
9 * 9 = 81
3 * 3 = 9
81 + 9 = 90
[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.

Step-by-step explanation:
Took the k12 math test
A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate of 87.5% the account has $1850.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest = P(1+r/n)^rt
A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate the account has $1850.
Compound Interest = P(1+r/n)^rt
[tex]\rm 1850 = 231 25 (1 + r/12)^{96}[/tex]
[tex]\rm 1850 = 231 25 (1 + r/12)^{96}\\\rm 1850 /231 25 = (1 + r/12)^{96}[/tex]
r = 87.5%
Thus, the interest rate percentage is 0.87 rate per year.

To compute the square of the length of a sloped side, you need to sum the squares of the rise and the run. For example, the square of the length of 'a' in triangle F is ...
a² = rise² + run² = 1² +2² = 1 +4 = 5
__
Additional comment
When computing the slopes of the various triangle sides, you need to pay attention to the sign of the "rise" for a positive "run."
For the distance purpose here, the rise and run are squared, so their signs are irrelevant. You can treat them all as positive numbers.

<a is 34 (half of 68)
<C is 56
triangle YRC is iscocles, YR and RX are both radius, so they are equal. So the base angles must be equal as well. we know that the central angle is 68, because arc YX is 68. to find the measure of angle C use the equation 2x+68=180 (2 of the same angle (x) + 68 makes all the angles in the triangle. 2x=180-68 2x=112x=56Skip E until the end
<G is 84
<G and the angle that is 96 make a linear pair <G + 96=180<G=84Arc YS is 112
Arc YS is = <Rfind <R<R and the angle across from ARC YX are a linear pair<YRX is 68<R+68=180<R is 112<D and F are 42
<D and <F are the base angles of an isosceles triangle (2 sides are the radius again)the central angle in this case is 962x+96=1802x=84x= 42so both D and F are 42now <E is 96
measure of an angle outside the circle with 2 rays touching the circle is the measure of the larger arc of the circle minus the smaller arc divided by 2the measure of the smaller arc is the same as <Gsmaller arc is 84the larger arc is 360-84the larger arc is 276276-84= 192divide by 2 to get <E192/2=96What is the surface area of this design?

Find the accumulated value of an investment of $14,000 at 10% compounded semiannually for 11 year
Answers
Given:
Principal = $14000
Rate of interest = 10% compounded semiannually.
Time = 11 years.
To find:
The accumulated value of the given investment.
Solution:
Formula for amount or accumulated value after compound interest is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is the principal values, r is the rate of interest in decimal, n is the number of times interest compounded in an year and t is the number of years.
Compounded semiannually means interest compounded 2 times in an years.
Putting [tex]P=14000,r=0.10,n=2,t=11[/tex] in the above formula, we get
[tex]A=14000\left(1+\dfrac{0.10}{2}\right)^{2(11)}[/tex]
[tex]A=14000\left(1+0.05\right)^{22}[/tex]
[tex]A=14000\left(1.05\right)^{22}[/tex]
[tex]A\approx 40953.65[/tex]
Therefore, the accumulated value of the given investment is $40953.65.
Answer:
A = $41,867.06
A = P + I where
P (principal) = $14,000.00
I (interest) = $27,867.06
Step-by-step explanation:
Given: Investment = $14,000 Annual Rate: 10% compounded semiannually = 11 year
To find: The accumulated value of an investment
Formula: [tex]A = P(1 + \frac{r}{n}) ^n^t[/tex]
Solution: First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 14,000.00(1 + 0.1/12)(12)(11)
A = 14,000.00(1 + 0.008333333)(132)
A = $41,867.06
Henceforth:
The total amount accrued, principal plus interest, with compound interest on a principal of $14,000.00 at a rate of 10% per year compounded 12 times per year over 11 years is $41,867.06.

Throughout New Jersey, the Federative Recruitment agency informs you of the average wage of mathematics in high schools.Unless you're in Florida and therefore don't know concerning Dale County Florida wages, this same work you've been given is well beyond the area whereby you know the compensation of teachers or instructors, you can't make any view.The other three given alternatives aren't related to the question. Thus option c is the correct one.
