The degree of the polynomial p(y) =(y-4)^3-y^3 is<br><br>Plz urgent

Scilla [17]

Answer:

The degree of polynomial is 2

Step-by-step explanation:

Given

$p(y) = (y -4)^3 - y^3$

Required

The degree

When expanded, $p(y) = (y -4)^3 - y^3$ is:

$p(y) =y^3-12y^2+48y-64-y^3$

Collect like terms

$p(y) =-12y^2+48y-64-y^3+y^3$

$p(y) =-12y^2+48y-64$

<em>The degree of freedom is 2</em>

The time required to complete a project is normally distributed with a mean of 80 weeks and a standard deviation of 10 weeks. Th

matrenka [14]

Answer: the due date would be 92 weeks

Step-by-step explanation:

Since the time required to complete a project is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = number of weeks.

µ = mean

σ = standard deviation

From the information given,

µ = 80 weeks

σ = 10 weeks

If a construction company bidding on this contract wishes to be 90 percent sure of finishing by the due date, the z score corresponding to 90%(90/100 = 0.9) is 1.29

Therefore,

1.29 = (x - 80)/10

x - 80 = 1.2 × 10

x - 80 = 12

x = 80 + 12 = 92

Please help! (listing BRAINLIST and giving points) :)

stepladder [879]

Answer:

(a) = 60

(b) = 70

Step-by-step explanation:

(a) Sum of all the angles of a triangle is 180

This is an equilateral Triangle

which means all the sides are equal since all the sides are equal that means all the angles are equal

$x + x + x = 180 \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60$

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

$40 + x + x = 180 \\ 40 + 2x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = 70$

bagirrra123 [75]

So we know each inch is 3 feet.

1:3.

13:?

So we multiply 13 by 3 to get the answer!

13:39

or 39 feet!

I hope this helped! :))
