Wayne and Winston are scuba diving and are ascending to the surface. The function y = 30x − 105 represents Wayne’s elevation in

feet in terms of the time in minutes he ascends. The table represents Winston’s elevation in feet in terms of the time in minutes he ascends. Assume that Wayne and Winston both ascend at a constant rate.
X= 0 and 3
Y= -100 and -16

which statements about this situation are true?

A) Wayne ascends at a faster speed
B) Winston ascends at a faster speed
C) Wayne and Winston ascend at the same speed
D) Wayne was deeper when he began ascending

How many x intercepts does the polynomial function y=(x-8)(x+3)^2
guajiro [1.7K]

Answer:

The answer is 2 x-intercepts

Step-by-step explanation:

To determine the x-intercepts we set y to zero and solve for x:

y=0

(x-8)(x+3)^2=0

The product of 2 factors is 0 means that one of them must be 0:

x-8=0 ⇒ x=8        →first x-intercept

or (x+3)^2=0 ⇒ x+3=0 ⇒ x=-3         →second x-intercept

Therefore the polynomial function two roots, so it has two x-intercepts x=8 and x=-3

Hope this helps :)

Which equation is a point slope form equation for line AB ?
Stells [14]

Answer:

y -5 = (3/4)(x -6)

Step-by-step explanation:

Between the two points, the line has a rise of 6 and a run of 8. Thus, the slope is ...

... m = rise/run = 6/8 = 3/4

The point-slope form of the equation of a line with slope m through point (h, k) is ...

... y - k = m(x - h)

For point B, (h, k) = (6, 5), so filling in the values gives ...

... y - 5 = (3/4)(x - 6)

What is an algebraic expression for 'two thirds of a number (d) to the third power' ?
horrorfan [7]
It is (2/3d)^3
Make sure the exponent is on the outside. This is because you are raising 2/3d. Not just D

Given

3x^{4} - 2x² + 15x² - 10

Factor the first/second and third/fourth terms )

= x²(3x² - 2) + 5(3x² - 2) ← factor out (3x² - 2) from each term

= (3x² - 2)(x² + 5)
