Answer 1

Answer:

sin∅ = 12/13

Step-by-step explanation:

use pythagorean theorem to find the missing side

a² + 5² = 13²

a² = 13² - 5²

a² = 169 - 25

a² = 144

a = 12

-----------------------------

Sin∅ = opp/hyp

sin∅ = 12/13

help please. really need answers to understand

Answers

Answer:

hmmmm.... each question here is relatively straight forward, the issue is that these questions basically represent an entire unit (possible two) of an Algebra II class... I can provide answers, but the explanation (if you don't know the basic ideas might be elusive, But I will try to help)

Step-by-step explanation:

1) A = P (1+ r/n) ^ nt

interest equation ... monthly compounding so n = 12 thus r gets divided by 12 and t get multiplied by 12

A = 10,000(1 + .04/12)^(3*12)

A = 10000(1.00333)^36

A = $11,272.71

========================

2) [tex]A = pe^{rt}[/tex]  

A = 15,000 [tex]e^{.06 t}[/tex]

18,000= 15,000 [tex]e^{.06 t}[/tex]

1.2= [tex]e^{.6 t}[/tex]

ln(1.2) = .06t (ln e)

.1823 / .06 = 3.03 years

Note: ln e = 1

==========================

[tex]3^{5x+1} = 27[/tex]

[tex]3^{5x+1} = 3^{3}[/tex]

thus: 5x+ 1 = 3

5x = 2

x = 2/5

==============================

f(x) = 5x - 12

y = 5x - 12

inverse

x = 5y - 12

5y = x + 12

y = 1/5 x + 12/5

=====================

fog(X) =

f(X) =6x+12

g(x) = x^2 + 3

fog(X) = 6(x^2 + 3)+12

           = 6x^2 + 18 + 12

            = 8x^2 + 30

Domain (- infinity, + infinity)

======================

vertex 3x^2 - 6x + 2

verted = [-b/2a, f(-b/2a)]

a=3 , b=-6 , c = 2

-b/2a = 6/6 = 1

f(-b/2a) = -1

vertex = (1,-1)

=======================

30x - .4x^2

-30/-.8 = 37.5

max rev =  30(37.5) - .4(37.5)^2 = $562.5

II ZPQR measures 75', what is the measure of SQR?
22
0 45°
0 539
097

Answers

Answer:

53degrees

Step-by-step explanation:

Find the diagram attached

<PQR = 75degrees

From the diagram'

<SQR + <PQS = <PQR

<SQR + 22 = 75

<SQR = 75-22

<SQR= 53degrees

Hence the measure of <SQR is 53degrees

Find the volume of the prism.

Answers

Answer:

  420 mm³

Step-by-step explanation:

The volume is given by the formula ...

  V = Bh

where B is the area of the triangular base, and h is the height.

The triangular base area is given by the formula ...

  A = 1/2bh

  A = 1/2(10.5 mm)(10 mm) = 52.5 mm²

Then the volume of the prism is ...

  V = (52.5 mm²)(8 mm) = 420 mm³

Jared flicked the arrow on this spinner four times, and the arrow landed on green each time. If Jared spins the arrow a fifth time what is the theoretical probability that it will land on green

Answers

Answer:

The correct answer would be 3/8.

Step-by-step explanation:

There are 3 greens on this spinner , and 8 in total , so there’sa probability of 3% that the arrow will land on green again .

The theoretical probability that it will land on green is 1.

What is the probability?

It is the likeliness of happening an event. It is calculated by the following formula:

Probability=number of events/number of total events.

How to calculate the probability?

Jared had flicked the arrow all the four times on the green ,it means that the probability that it is landed on green each time is 100%. So the probability that it will land on green fifth time also is 1.

Answers

Answer:

2/3

Step-by-step explanation:

Find two points

(0,-2) and (3,0)

Using the slope formula

m = (y2-y1)/(x2-x1)

   = (0- -2)/(3-0)

  = (0+2)/(3-0)

   = 2/3

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

From the graph, we can see the line passes through the points (3,0) and (0,-2).

The slope of a line, [tex]m[/tex], that passes through points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by [tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let [tex](x_1,y_1)\implies (3,0)[/tex] and [tex](x_2,y_2)\implies (0,-2)[/tex].

The slope of the line that passes through these points is:

[tex]m=\frac{-2-0}{0-3}=\frac{-2}{-3}=\boxed{\frac{2}{3}}[/tex]
