A water gauge in a pond measured 2358 in. At the beginning of the week. After five days of rain, the gauge read 3414 in. By how much did the water level rise?

Answers

Answer:

1056 inches

Step-by-step explanation:

Given that :

Initial measurement = 2358 in

Guage level after 5 days of rain (final reading) = 3414 in

Change in water level rise :

Final reading - Initial reading

(3414 - 2358) in

= 1056 inches

Ryan bought a brand new car for $18,000. Its value depreciated at a rate of 1.2%.

Write a function to represent the value of the car as a function of time.

A. v(t)=18000(0.012)^t

B.V(t)=18000(1.2)^t

C.v(t)=18000(98.8)^t

D(t)=18000(0.988)^t

Answers

Answer:

A(t)= 18000(0.988)^t

Step-by-step explanation:

Given data

Ryan bought a brand new car for $18,000

Its value depreciated at a rate of 1.2%

Let us use the compound expression

A= P(1-r)^t

substitute

A= 18000(1-0.012)^t

A(t)= 18000(0.988)^t

Hence the expression is A(t)= 18000(0.988)^t

A function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t

Exponential function

The standard exponential equation is in the form y = ab^x

b is the rate which can be growth or decline

If the value of b < 1, it is a depreciationIf the value of b > 1, it is an appreciation

If Ryan bought a brand new car for $18,000 and its value depreciated at a rate of 1.2%, the exponential equation represented by this statement is;t

v(t) = 18000(1-0.0012)^t

v(t) = 18000(0.988)^t

Hence a function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t

Y=4-2x 3y-2x=4 solve using substitution

Answers

Answer:

x=1 y=2

Step-by-step explanation:

y=4-2x             3y=4+2x

3*(4-2x)=4+2x

12-6x=4+2x

12-4=2x+6x

8x=8

x=1

y=4-2*1

y=2

First turn the equation y=4-2x into a y=Mx+b formula. It would be y=-2x+4. Then plug it in into the y on the second equation. I’d be 3(-2x+4)-2x=4. Then solve. The answer is x=1. Hope it helped. :)

The ratio of Ali's to Beth's score is 5:3. Ali
scored 10 more marks than Beth. Clare scored
7 more than Ali. Find the score of all three.

Answers

Answer:

Ali 25

Beth 15

Clare 32

Step-by-step explanation:

Here, we want to get the score of the three

let Ali’s score be x

He scored 10

more than Beth; Beth score will be x-10

Let us now work with the ratio

x/x-10 = 5/3

3x = 5(x-10)

3x = 5x - 50

5x-3x = 50

2x = 50

x =

50/2

x = 25

Beth will

score 25-10 = 15

score had 7 more than Ali,

25 + 7 = 32

[tex]x \approx 24\degree [/tex]

Step-by-step explanation:

In triangle BAC, by Pythagoras theorem:

[tex]AC^2 = BC^2 -BA^2 [/tex]

[tex]AC^2 = (15)^2 -(9)^2 [/tex]

[tex]AC^2 = 225 - 81[/tex]

[tex]AC^2 = 144[/tex]

[tex]AC = \sqrt {144} [/tex]

[tex]AC = 12\: cm [/tex]

In triangle ABD,

[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]

[tex] \tan \angle ABD =\frac{5}{9} [/tex]

[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]

[tex] \angle ABD =29.054604099\degree [/tex]

[tex] \angle ABD =29.05\degree [/tex]

Next, in triangle ABC, by sine rule:

[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]

[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]

[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]

[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]

[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]

[tex]29.05\degree+x =53.130102354\degree [/tex]

[tex]29.05\degree+x =53.13\degree [/tex]

[tex]x =53.13\degree- 29.05\degree[/tex]

[tex]x =24.08\degree [/tex]

There is no graph attached

the question is "get y by itself" and the equation is 5x + 5y =15

Answers

Answer:

y=3-x

Step-by-step explanation:

Answer:

First we get y on one side by itself.

5x+5y=15

We move x over to the other side.

5x-5x+5y=15-5x

Simplify.

5y=15-5x

Now we remove the coefficient from y.

5y/5=(15-5x)/5

Simplify.

y=15/5-5x/5

y=3-x

The answer is y=3-x
