Answer:

Step-by-step explanation:

C.

The equatorial radius of Saturn is approximately ten times that of Earth.

The ordinal is identical

The exponent of 10 is 4 - 3 = 1 greater for Saturn than for Earth

10¹ = 10 times

Becky Anderson must pay a lump sum of $6000 in 5 yr. If only $5000 is available to deposit right now, what annual interest rate
34kurt

Hello!

Out equation is: A=P(1+\frac{r}{n} )^t^n

A= 6000

P=5000

N=1

T=5

R= What we are trying to find

This means we will have 6000=5000(1+r)^5

Divide both sides by 5000:

\frac{6000}{5000} = (1+r)^5

Move the power to the other side by rooting both sides:

\frac{6000}{5000} ^1^/^5 = 1+r

Subtract 1 from both sides:

\frac{6000}{5000} ^1^/^5 -1 = r

Now we just need to calculate: R = 0.03713728...

I don't know how many decimal places you can have, but I will round to 2. This will give you an Interest Rate of 3.71%.

I hope this helps! :)

From the given sides of 16, 14, and 21, determine what type of triangle it will form (right, acute, obtuse, none).
Komok [63]

Answer:

It is an acute triangle.

Step-by-step explanation:

It would be much easier for you to see where I'm getting at if you draw a diagram.

Assume this triangle is labelled ABC where a = 14, b = 21, and c = 16.

cos A = (16^2 + 21^2 - 14^2)/(2(16)(21))

∠A = cos^-1(0.82291...)

∠A ≅ 34.6°

cos B = 16^2 + 14^2 - 21^2)/(2(16)(14))

∠B = cos^-1(0.024...)

∠B ≅ 56.8°

∠C = 180 - (∠A + ∠B)

∠C ≅ 56.8°

Since there is no right-angle nor is there an obtuse angle,

Therefore the triangle is an acute triangle.
