Answer:

1. b=6

2.b=8

3.a=30

I can't get the correct answer for 4 and 5 hope what I've got so far helps.

Step-by-step explanation:

1. 8^2+b2=10^2

64+b2=100

b2=36

then square to get

b=6

2. 15^2+b2=17^2

225+b2=289

b2=64

then square to get

b=8

3. a2+40^2=50^2

a2+1600=2500

a2=900

then square to get

a=30

I can't get the correct answer for 4 and 5 hope what I've got so far helps.

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

gavmur [86]

Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .

$y-(-1)=-2 (x-5)$

$y+1=-2(x-5)$

This is the equation of the line with slope -2 that passes through (5,-1).

-3x^2 – 24x – 13 = -13

Fudgin [204]

$\begin{gathered} -3x^2-24x-13=-13 \\ \text{ Express it as:} \\ 3x^2+24x+26=0 \\ 3x^2+24x=-26 \\ 3(x^2+8x+16)=?-26 \\ 3(x+4)^2=48-26 \\ 3(x+4)^2=22 \end{gathered}$

1. Alice invests $1000 at 2% interest compounded monthly over a 5 year period. Assuming no other money is deposited or withdrawn

eduard

Answer:

$1,105.08.

Step-by-step explanation:

Given that Alice invests $ 1000 at 2% interest compounded monthly over a 5 year period, assuming no other money is deposited or withdrawn, to determine what is the total amount of money in her account after 5 years, the following calculation must be performed:

X = 1,000 (1 + 0.02 / 12) ^ 5x12

X = 1,105.08

Thus, the amount of money in her account after 5 years would be $ 1,105.08.
