I need help this is a tangent and secant problem and I'm confused

Answers

Answer:   110 degrees

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

Work Shown:

x = measure of minor arc CL

angle J = ( (far arc) - (near arc) )/2

angle J = ((red arc) - (yellow arc))/2

angle J = ( (minor arc CL) - (minor arc CK) )/2

35 = ( x - 40 )/2

35*2 = x-40

70 = x-40

x-40 = 70

x = 70+40

x = 110

Minor arc CL = 110 degrees

find out the total volume of cube _Edge Length =6 inches​

Answers

Given:

The edge length of a cube = 6 inches

To find:

The volume of the cube.

Solution:

We know that, the volume of a cube is

[tex]V=a^3[/tex]            ...(i)

Where, a is the edge length.

Substituting a=6 in (i), we get

[tex]V=(6)^3[/tex]

[tex]V=216[/tex]

Therefore, the total volume of the cube is 216 cubic inches.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables.

The parent function is given as,

f(x) = x²

The parent function is shifted upward by 4 units. Then replace f(x) with g(x) - 4. Then the equation is written as,

g(x) - 4 = x²

g(x) = x² + 4

The equation of the red curve on the graph will be g(x) = x² + 4. Then the correct option is D.

richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month

Answers

Answer:

His gross pay for the month is $4,509.50

Step-by-step explanation:

The commission Richard Klein earns for oil change = 3.00%

The commission he earns for tune ups = 5.00%

The commission he earns for auto parts sales = 6.25%

The minimum salary he is guaranteed = $2,450.00

The amount he brought in last month includes;

1) $2,500.00 in oil changes

2) $4,500 in tune ups

3) Sold $28,200.00 in parts

The amount he earns last month in commission are;

3/100 × 2,500 = 75 in oil changes

5/100 × 4,500 = 225 in tune ups

6.25/100 × 28,200 = 1762.5 in parts sold

The total commission = 72 + 225 + 1762.5 = 2,059.5

∴ The total commission = $2,059.5

The amount he makes as salary = $2,450.00

Richard Klein's gross pay for the month = His total pay for the month

Therefore;

Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

Answers

Answer and Step-by-step explanation:

The answer is the last answer choice.

g(x) = [tex]-(x + 2)^2 + 1[/tex]

We don't even have to look at the numbers to tell that this is the correct answer. We look at what is being placed there.

The equation for a transformed function is:

f(x) = [tex]a(x-h)^2 + k[/tex]

a determines the scale of the graph and whether the graph opens up or down.

h determines whether the graph shifts left or right.

k determines whether the graph shifts up or down.

We see that there is a -1 for a, which means the graph will be facing downwards. We see a 2 for where h is, but it really is a -2, and when it becomes a positive after simplifying, the graph will shift to the left.

k is a positive 1, so the graph will be shifted up 1 unit.

Thus, the answer is the last answer choice.

A package of mixed lettuce seeds contains 150 green lettuce seeds and 50 red lettuce seeds. What is the probability that a randomly selected seed will be a red lettuce seed? Write your answer as a percent.​

Answers

Answer:

25%

Step-by-step explanation:

I used relative frequency approach

n(total number of seeds)= 150+50=200.

probability (selecting a red lettuce) = red lettuce divided by the total number of seeds.

probability (selecting red lettuce) = 50/200 = 0.25

in percentage, probability = 0.25*100= 25%✓

hope this helps

Answer:

[tex]\frac{141}{92}[/tex]

Step-by-step explanation:

1) First, convert the mixed numbers to improper fractions.

[tex]5\frac{7}{8}[/tex] ÷ [tex]3\frac{5}{6}\\[/tex]

[tex]=\frac{47}{8}[/tex] ÷ [tex]\frac{23}{6} \\[/tex]

2) To divide fractions, find the reciprocal of the second fraction by flipping it, or switching the places of its numerator and denominator. Then, multiply the two fractions by multiplying their numerators and denominators together. Then, simplify the result to find the answer.

[tex]\frac{47}{8}[/tex] × [tex]\frac{6}{23}[/tex]

[tex]=\frac{282}{184} \\=\frac{141}{92}[/tex]
