Answer:

h = 2√3

Step-by-step explanation:

Using pythagorean's theorem:

a² + b² = c² such that

h² + 2² = 4²

h² = 16 - 4

h² = 12

h= √12

h = √ 4 * 3

h = 2 √3

Note:

I divided the base and made it 2.

The other slant side = 4

About Slope Intercept Form:

y = mx + b
m is the slope
b represents the y-intercept

For the graphing one, since the slope is positive, you have to go up 5 and right 2 because the slope equals <u>rise</u>

run.

5 represents rise & 2 represents run. Then -4 is the starting point, the y-intercept.

Hope this info helps!! :)

Suppose $20,000 is invested into an account where interest is compounded semiannually. After 30 years the balance is

denis-greek [22]

Compound Interest Formula: $A=P(1+\frac{r}{n})^{nt}$

P = initial investment of 20,000

r = interest rate (What we need to find)

n=number of compounding periods per year (Semiannually means twice per year)

A= Amount after t-years

Okay, let's plug it all in.

41,951 = 20000 (1 + r/2)^2(30)

41,951/20000 = (1 + r/2)^60

(41,951/20000 )^1/60 = 1 + r/2

(41,951/20000 )^1/60 - 1 = r/2

2( (41,951/20000 )^1/60 - 1 ) = r

0.02484539... = r

0.02484 * 100 = 2.48% rounded to the nearest hundredth of a percent

I hope I've helped! :)

During 14 spins, a spinner landed on blue 4 times. If you spin the spinner once, what is the experimental probability that it wi

pychu [463]

Answer:

2/7

Step-by-step explanation:

Since 4 out of 14 times it landed on blue, it must have a 4/14 experimental probability of 4/14 for landing on blue. 4/14 simplifies to 2/7.

Find the slope of the line below. *

earnstyle [38]

Answer:

I believe it would be -3,4.

Step-by-step explanation:

To find slope you use rise over run, where you count up first, then go to the side. If you count down on the left you count 3 boxes, but since its going down its negative. And to get the run you count over 4. Meaning it's -3,4
