andrew-mc [135]

Answer:

B, 11000

Step-by-step explanation:

assuming a 365 day year...

10500*(1+.15)^{\frac{123}{365}}= 11006.35813

Cyrus, Ray and Billy visited the playground where their friends made a triangle out of string 9.5 m, 10.0 m, and 10.5 m long, an
Mkey [24]

Answer:

Billy next to the 65 degree angle

Ray next to the 60 degree angle

Cyrus next to the 55 degree angle

if we were to put this into A squared + B squared = C squared it would be Cyrus squared + Ray squared = Billy squared  

Also lol Billy Ray Cyrus (Miley Cyrus Dad)

Explaination:

It literally says it right here "Cyrus to stand by the 55o angle, Ray by the 60o angle, and Billy by the 65o angle. Determine which vertex each boy should stand next to."

2x2 − 2z4 + y2 − x2 + z4 if x = −4, y = 3, and z = 2.
gavmur [86]
2(-4)2=-16
-2(2)4=-16
(3)2=6
-(-4)2=8
(2)4=8
8+8=16+6=22-16=6-16=-10
-10 is the final answer.

Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x
bulgar [2K]

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

\frac{y}{x} = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

\frac{t}{p}=1.08

C. Equation: x=\frac{m}{4}

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

\frac{m}{x}=4

D. Equation: V=12s^{2}

This equation is NOT proportional because side length is squared, so it is not constant linearly.

How do you find change in y when given slope and change in y pls help WILL GIVE BRAINLIEST!!!​
arlik [135]

The slope (m) is the change in Y over the change in X.

Slope = Y/X

The slope is given as -3/4 , so y would be 3 and X would be 4.

Y = 3
