Can someone help me with one of these? Factor using the X method please!

Answers

Answer 1

Answer:

Step-by-step explanation:

6. x² + 8x + 7

= x² + 7x + x + 7

= x (x + 7) + 1 (x + 7)

= (x + 1) (x + 7)

Option D is the answer.

7. x² - x - 72

= x² - 9x + 8x - 72

= x(x - 9) + 8(x - 9)

Option B is the answer.

8. x² - 49

= (x - 7) (x + 7) [formula used a² - b² = (a-b)]

Option D is the answer.

9. 9x² - 54x + 72

= 9(x² - 6x + 8)

= 9(x² - 4x - 2x + 8)

= 9[x(x-4) -2 (x-4)]

= 9[(x - 2) (x - 4)]

= Option A is the answer.

10. x⁴ - 3x³ - 10x²

= x² (x² - 3x - 10)

= x² (x² - 5x + 2x - 10)

= x² [x (x-5) + 2 (x-5)]

= x² (x+2) (x-5)

Option A is the answer.

You might think that the angle between the hour and minute hand at 2:20 is 60 degrees, but it is not! The hour hand has moved beyond the 2. Calculate the angle between the clock hands at 2:20.

Answers

Answer:

70 degrees

Step-by-step explanation:

Moving from one hour number to the next (12 to 1, 3 to 4, etc) moves the hand of the clock 30 degrees. Using this, we know that the hour hand moved 60 degrees to get to the hour number 2. Then, the angle the hour hand moved because of the minute hand can be calculated by doing (20/60)*30=10. So the final answer would be 70 degrees.

Let f be differentiable such that f(-2)=3,f(3)=5, f'(-2)=4 and f'(3)=6. Let g be differentiable functions such that g(x)=f^-1 (x) for all x. What is the value of g'(3)

Answers

Answer:

[tex]g'(3)=\frac{1}{4}[/tex]

Step-by-step explanation:

There is a rule in calculus that tells us that:

[tex]g'[f(x)]=\frac{1}{f'(x)}[/tex]

In this case, we know that f(-2)=3, therefore:

g'(3)=g'(f(-2))

So, if we used the rule, we would get that:

[tex]g'[f(-2)]=\frac{1}{f'(-2)}[/tex]

we know that f'(-2)=4, so:

[tex]g'[f(-2)]=\frac{1}{4}[/tex]

or:

[tex]g'[3]=\frac{1}{4}[/tex]

What is the surface area of a dome (a half sphere) with a radius of 6 meters?
72 pi meters squared
48 pi meters squared
24 pi meters squared
144 pi meters squared

Answers

Answer: 72π meters squared.

Step-by-step explanation: Given that the radius is 6 meters, use the sphere surface area formula to find the surface area of the half-sphere;

Replace the value in the formula: A=4πr² → A=4π6²Solve the exponent first: A=4π6² → A=4π36The order of the multiples does not affect the total, so we can multiply 4 times 36 first: A=4π36 → A=144π144π is the surface area of the whole sphere, so half the sphere will be 72π. In conclusion, the surface area of the dome will be 72π meters squared.

The perimeter of a rectangle is 36 meters. If the length of the rectangle is 10 meters, what is the width (in meters)?

Answers

The width is 8. The length is 10 so 10+10 equals 20. You subtract 20 from 36 you get 16. 16/2 is 8. If you add 8+8+10+10 you get 36.

The width would have to be 8
