Which graph shows the zeros of the function f(x) = 2x2 + 4x – 6 correctly?

Answers

Answer:

Divide through by 2 .

x2 - 2x - 3 = 0 What two numbers add to -2 and multiply to -3 ? → +1 and -3

So...we can factor it like this...

(x + 1)(x - 3) = 0 Set each factor equal to zero and solve for x.

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

Josephine started a business selling cosmetics. She spent $4500 to obtain her merchandise, and it costs her $200 per week for general expenses. She earns $550 per week in sales.

What is the minimum number of weeks it will take for Josephine to make a profit?

550w<4500+200w

200w≥4500+550w

550w>4500+200w

200w>4500+500w

Answers

Answer:

550w>4500+200w

Step-by-step explanation:

Expenses: $4500 + $200 per week

Income: $550 per week

We want income to be greater than expenses

A plane flies 1.6 hours at 150 mph on a bearing of 10°. It then turns and flies 9.1 hours at the same speed on a
bearing of 100°. How far is the plane from its starting point?

Answers

9514 1404 393

Answer:

1386 miles

Step-by-step explanation:

The plane flies ...

(150 mi/h)(1.6 h) = 240 mi

on its first leg. Then it flies ...

(150 mi/h)(9.1 h) = 1365 mi

on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.

c² = 240² +1395² = 1920825

c = √1920825 ≈ 1385.94

The plane is about 1386 miles from its starting point.

37=-3+5(x+6), Please provide explanation.

Answers

Answer:

x=2

Step-by-step explanation:

youd distribute the 5 first so the equation is now

37=-3+5x+30

then group the common terms (-3 and 30 in this case)

37=5x+27

now subtract 27 from both sides to start to isolate 5x

10=5x

divide by 5 to find x

2=x

hope i helped :)

37=−3+5(x+6)
37 = -3 + (5)(x) + (5)(6)
37 = -3 + 5x + 30
37 = (5x) + (-3 + 30)
37 = 5x + 27
5x + 27 =37
5x + 27-27 = 37-27
5x= 10
Divide 5 on both side and you get x= 2

Multiply each equation by a constant that would help to eliminate the y terms.
2x-5y = -21
3x-3y = -18
What are the resulting equations?
6x-15y = -63
- 15x+15y = 90
6x-15y = 63
-15x+15y = 90
6x-15y=-63
- 15x+ 15y = -90

Answers

6x-15y=-63
-15x+15y=90

This is because you are multiplying the first equation by a constant of 3 and the second equation by 5 so that you can have -15y and +15y which will cancel each other out.

Answers

Answer:

432 inches.

Step-by-step explanation:

The formula for finding the area of a triangle is;

[tex]\frac{b*h}{2}[/tex]

Using this, we can find the area of each individual piece.

[tex]\frac{6*6}{2} =18[/tex]

Now that we have this, we simply multiply 18 by 24, which gives us 432.

M is directly proportional to R cubed a)R = 4, M = 160 find M when R = 2 b) work out the value of R when M=540

Answers

Answer:

a k (proportionality constant) = 2.5

b. r = 6

Step-by-step explanation:

Here, we want to solve a variation

m = k * r^3

160 = k * 4^3

160 = 64k

k = 160/64

k = 2.5

b) secondly;

From;

540 = 2.5 * r^3

r^3 = 216

r = cube root of 216

r = 6

Answer:

the answer is d

Step-by-step explanation:

a standard deliation is how streaded out the number thing is

Answer:

Carlita is correct because Dot Plot A is more spread out than Dot Pot B

Step-by-step explanation:

Dot Plot B is skewed left which means most of its data is on the left side so it will mostly have lower numbers as data. On the other hand, Dot Plot A is spread out so it has both low numbers but also some higher numbers.
