Answer:

b=1399.43

Step-by-step explanation:

We know our A side (length CH) is 3960

First we have to find our c side or length CE

Add 3960 and the altitude of 240 which equals 4200

then use the Pythagorean Theorem of A squared + B squared = C squared

if you plug that in its

3,960 squared + B squared = 4200 squared

If you calculate that its

15,681,600 + b squared = 17,640,000

then you want to isolate the variable

youll want to subtract 15, 681,600 from both sides of the = sign

this gives you b squared = 1,958,400

then youll have to find the square root of both

the square root of B squared is B

the square root of 1,958,400 is 1399.43

so B = 1399.43

Uta invests an amount into a compound interest investment account that pays 6% a year. After six years, she withdraws her total
AnnZ [28]

Answer: $352.48

Step-by-step explanation:

Hi, to answer this question we have to apply the formula:

A = P (1 + r)^t

Where  

A: total balance after invest

P: principal amount invested

r = interest rate (in decimal form)

t = time (years)

Replacing with the values given:

500= P (1+0.06)^6

Solving for P:

500 = P (1.06)^6

500 / ( (1.06)^6)=P

500 / 1.4185 =P

$352.48= P

The slope of a line is 7/10 . One point on the line has coordinates (1, 2). Which ordered pair represents another point on the l
mash [69]
(x,y)

y=mx+b
m=slope
b=yintercept
slope=7/10
one point is (1,2) or x=1, then y=2
find b
y=7/10x+b
2=7/10(1)+b
2=7/10+b
minus 7/10 both sides
1 and 3/10=b
13/10=b
y=7/10x+13/10
input values for x and get values for y
one point is (0,13/10)
