Answer:

acute

Step-by-step explanation:

Angles between 0 and less than 90 are acute

A 90 degree angle is right

Greater than 90 and less than 180 is obtuse

180 degree angles are straight

45 degrees is less than 90 so it is acute

Solve for . Simplify your answer as much as possible. please help

Sonja [21]

Answer:

$x=-6$

Step-by-step explanation:

So we have the equation:

$-34=7(x+8)+8x$

First, distribute the 7 into the (x+8) and simplify:

$-34=7(x)+7(8)+8x\\-34=7x+56+8x$

Combine the like terms 7x and 8x by adding them together:

$-34=56+15x$

Subtract 56 from both sides to isolate the x:

$-34-56=15x+56-56\\15x=-90$

Divide both sides by 15 to get x:

$x=-90/15=-6$

If u is inversely proportional to the square of v and u is 4/9 when v is 3, find u when v is 8

LenKa [72]

Answer:u=1/16

Step-by-step explanation:

u is inversely proportional to v^2

u=k× 1/v^2

u=k/v^2

When U=4/9 when v=3

4/9=k×1/3^2

4/9=k×1/9

4/9=k/9

Cross multiply

4×9=k×9

36=9k

Divide both sides by 9

36/9=9k/9

4=k

When v= 8, u=?

u=k/v^2

Recall k=4

u=4/8^2

u=4/64

u=1/16

max invests $6000 in a savings account for 3 years. the account pays compound interest at a rate of 1.5% per year for the first

madam [21]

Answer:

2.1%

Step-by-step explanation:

The formula for compound interest is given as:

$A=P(1+I)^n\\\\P-Principal \\A-amount\\i-compound \ interest \ rate$

Given the Principal amount as $6000, and the rate in the first two years as 1.5%:

$A=P(1+i)^n\\\\A_2=6000(1+0.015)^2\\\\A_2=6181.35$

We compound $A_2$ for 1 year at rate i to obtain $6311.16:

$A=P(1+i)^n, n=1, i=i, P=6181.35, A=6311.16\\\\6311.16=6181.35(1+i)^1\\\\\frac{6311.16}{6181.35}=(1+i)\\\\i=\frac{6311.16}{6181.35}-1\\\\i=0.02100$

Hence, the compound interest rate in the third year is 2.1%
