what is the point of this

Answer:

Option B: 4

Step-by-step explanation:

From the image, the correct function is;

f(x) = x³ -5x² - 8x + 48

Now, the x-intercept occurs when y = 0.

Thus;

x³ - 5x² - 8x + 48 = 0

So we are looking for values of x that will make y = 0.

Let's try the options;

Let's try x = -4;

(-4)³ - 5(-4)² - 8(-4) + 48 = -64 - 80 + 32 + 48 = -64 ≠ 0

So, x = -4 is not an x - intercept

Let's try x = 4;

(4)³ - 5(4)² - 8(4) + 48 = 64 - 80 - 32 + 48 = 0

So,x = 4 is an x-intercept

Let's try x = - 2;

(-2)³ - 5(-2)² - 8(-2) + 48 = -8 - 20 + 16 + 48 = 36 ≠ 0.

So, x = -2 is not an x-intercept.

Let's try x = 2;

(2)³ - 5(2)² - 8(2) + 48 = 8 - 20 - 16 + 48 = 20 ≠ 0

So, x = 2 is not an x-intercept

Answer:

A. m<R, m<S, m<Q

Step-by-step explanation:

In a triangle, the length of each side determines the size of the angle opposite it. Thus, the longer the side, the bigger the size of the angle opposite it. The shorter the side, the smaller the size of the angle opposite it.

In ∆QRS, we have the following:

✔️The longest side is RS = 16. <Q is opposite to RS, therefore <Q is the largest angle.

✔️The medium side is QR = 15. <S is opposite to QR, therefore <S is the medium angle.

✔️The shortest side is SQ = 9. <R is opposite to SQ, therefore <R is the smallest angle.

From smallest to the largest we would have:

m<R, m<S, m<Q

Answer:

A. $56,182

Step-by-step explanation:

$3131 x 14= $43834

$882 x 14= $12348

$43834 + $12348= $56,182

$56,182 x 1=  $56,182

Step-by-step explanation:

HERE,

as,it is a right angle triangle,

x=[tex]\tt{\sqrt{8^2+6^2} }[/tex]

[tex]\tt{ x=\sqrt{64+36} }[/tex]

[tex]\tt{ x=\sqrt{100} }[/tex]

[tex]\tt{x=10km. }[/tex]

Answer:

28.91×10^48

hope it helps.

Because they both have the same exponent, just add the numbers together:

5.9 + 4.9 = 10.8

So now you have:

5.9 x 10^24 + 4.9 x 10^24 = 10.8 x 10^24

A scientific number can only have 1 number to the left of the decimal, so you need to move the decimal one place to the left. When you move the decimal to the left you add to the exponent.

The answer is: 1.08 x 10^25

Answer:

  3/7 acres per hour

Step-by-step explanation:

To find acres mowed per hour, divide acres mowed by hours:

  (3/4 ac)/(1 3/4 h) = (3/4)/(7/4) ac/h = 3/7 ac/h

Ginger's unit rate is 3/7 acres per hour.

Answer: 3/7!

Answer:

76 feet

Step-by-step explanation:

let 'd' = distance from bottom of cliff and ship

sin 37 = sin 53

    d           100

0.61 = 0.8

  d         100

cross-multiply:    61 = .8d

                            d = 76

I assumed the bottom of the cliff and the shore formed a 90 degree angle - which leaves the 37° angle and a 53° angle

Answer:

Step-by-step explanation:

27. the sum of 2 complementary angles=90

8x-17+5x-10=90

13x=90+27

13x=117            x=9

28. the sum of supplementary angles=180

17x-12+3x-48=180

20x=180+60

20x=240

x=120

Answer: CHAA

Step-by-step explanation:

Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.

Explanation: By applying the circumference into the equation r = [tex]\frac{C}{2\pi }[/tex], we get r = [tex]\frac{78.8}{2\pi }[/tex]which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.
