Find the solutions of this quadratic.
f(x)=(x-8)(x+4)

Answer:

57degrees

Step-by-step explanation:

The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)

Taking the sum of the angles and equating to 180

5x-4 + 4x+1 + 4x+1 = 180

5x+4x+4x-4+1+1 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

x =182/13

x = 14

Get m<E

m<E = 4x+ 1

m<E = 4(14)+ 1

m<E = 56+1

m<E = 57degrees

Hence the measure of m<E is 57degrees

Answer: D / none are true

Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, BUT if you look closely at the graph, the slope of the graph is actually 2x.

Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.

The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.

Answer:

Step-by-step explanation:

It is a straight line also known as proportional. The first impression, A appears to be accurate, but closer inspection reveals that the graph's slope is actually 2x. 18 (x = 0/y intercept) and ends at x = 1, where little y is at 16. Any time x expands by one, the y value falls by two. This says that the graph's equation is -2x + 18 = y.

Answer: they are equal because the exponents are equal. Right there are in different order but they are still the same.

Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

233445.54 gallons  (from conversion tables)

Answer:

3a

Step-by-step explanation:

the common factors are what make up the terms. 12a is divisible by 3a

9a^2 is divisible by 3a

12a/3a = 4

9a^2/3a

(9a × 9a) / 3a = (9a × 3)

The greatest factor of both 12a and 9a² is; C: 3a

We want to find the greatest common factor of 12a and 9a². Now, let us first list the factors of both expressions;

Factors of  12a are; a, 1, 2, 3, 4, 6, 12, 1a, 2a, 3a, 4a, 6a, 12a

Factors of  9a² are; 1, 3, 9, 1a, 3a, 9a

The greatest factor that is common to both 12a and 9a² is 3a

Answer:

$50.50

Step-by-step explanation:

From the above question, we are to find the total cost of the tickets Mr Montes bought

An adult ticket to the school play cost $14.75.

A child ticket cost $5.25.

Mr. Montes bought 2 adult tickets and 4 child tickets.

Hence, the total cost is

= 2 × $14.75 + 4 × 5.25

= $29.5 + $21

= $50.50

Answer:

the property of being perpendicular is the relationship between two lines which meet at a right angle.

parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.

Answer:

3

Step-by-step explanation:

A common difference is found in arithmetic sequences. The simplified formula for arithmetic sequences, which is what is used here, is [tex]a_{n}=dn-a_{0}[/tex]. Where d is the common difference and [tex]a_{0}[/tex] is the zeroth term. So, in the given equation 3 must be the common difference.

Answer:

Answer:

The probability of landing on 8 twice is 1/64

Step-by-step explanation:

If you spin the spinner once, there are 8 possibilities each time (1-8). The possibility of landing on the number 8 is 1 of these 8 possibilities. Its probability is therefore 1/8

Each spin is independent. In other words, the spins do not affect each other. The number you land on during the first spin does not impact the second spin's number. The probability of landing on 8 the second time is the same as the first time: 1/8

Because the two events are independent, we find the probability of them both occurring by multiplying them together.

1/8 times 1/8= 1/64

Answer:

4th option

Step-by-step explanation:

let y = f(x) , then rearrange making x the subject, that is

y = 4x ( divide both sides by 4 )

[tex]\frac{1}{4}[/tex] y = x

Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then

[tex]f^{-1}[/tex] (x) = h(x) = [tex]\frac{1}{4}[/tex] x

Answer:

75%

Step-by-step explanation:

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %

Given the following

Total cards = 4 (6,7,8,9)

If the card is not 9, the required card will be (6,7,8)

Number of cards that are not 9 is 3

Probability = expected/total

Pr(not 9) = 3/4

express as percent

Pr(not 9) = 3/4×100

Pr(not 9) = 75%

Answer:

50%

Step-by-step explanation:

There are 4 cards, numbered 6, 7, 8, and 9. The numbers greater than 7 are 8 and 9. There are 2 numbers greater than 7.

P(greater than 7)  =  

2

4

Write your answer as a decimal. Then convert your answer to a percentage.
