Answer:
258 cm PLZ GIVE ME BRAINLIEST
Step-by-step explanation:
Since the chord is given as 80cm, we know from the definition of a chord that it is equidistant to both sides of the circle. Therefore, half the chord is 40. The extension of the center to the chord is perpendicular to the chord(definition of a chord). Therefore, if we connect the center of the circle to the edge of the chord, it's a right triangle. Also the center of the chord is the radius of the circle. Pytharogean theorem: 40^2 + 9^2=r^2 : 1681=r^2: r=41. The radius is 41. Curcumference of circle: pi*2*r : pi*2*41 : pi*82= 258 cm.

Zach has an above-ground pool that has a radius of 5.5 feet. He wants to put a new wall liner around his pool and needs to know the circumference of the pool. Find the circumference of the pool to the nearest hundredth.
Answers
Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

Sheldon made a deposit into an account that earns 8% simple interest. After 8 years Sheldon earns $800. What was his initial deposit?
Answers
Answer:
$1250
Step-by-step explanation:
Given data
Rate= 8%
Time= 8years
Simple interest= $800
Required
The principal P
We know that the expression for simple interest is given as
SI=PRT/100
substitute
800= P*8*8/100
cross multiply
800*100= 64P
80000=64P
divide both sides by 64
P= 80000/64
P=$1250
Hence the initial deposit was $1250

Answers
Answer:
log Subscript 3 Baseline StartFraction z squared Over 4 EndFraction
Step-by-step explanation:
The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]
Logarithm and indicesGiven the logarithmic expression;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]
We are to write it as a single logarithm
Using the product and quotient law of logarithm;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]
Simplify the final result to have:
[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]
Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

APR of 0.995%. How much money would a $1000 investment be worth at the end of 5 years
Answers
Answer:
The amount in 5 years will be $1,050.75
Step-by-step explanation:
Here, we want to calculate the worth of the given amount of money in the next 5 years
We use the compound interest formula here;
A = P(1 + r/n)^nt
A is the amount after the given number of years
P is the amount invested which is $1,000
r is the rate which is 0.995% which is 0.995/100 = 0.00995
n is the number of times per year interest is compounded and that is 1
t is the number of years which is 5
substituting these values, we have
A = 1000( 1 + 0.00995/1)^5
A = 1000(1.00995)^5
A = $1,050.75
