Answer:

-4 < x < 3

Step-by-step explanation:

<u>Information from Parts 1-4 of the same question:</u>

brainly.com/question/28193969

$f(x)=-x+3$

$g(x)=x^2-9$

A = (3, 0)

<u>Information from Parts 5-8 of the same question:</u>

D = (-4, 7)

The values of x for which g(x) < f(x) are the values of x between the points of intersection of the two functions: points D and A.

From part (2) of the question, we found that A = (3, 0).

From part (5) of the question, we found that D = (-4, 7).

Therefore, the values of x for which g(x) < f(x) are -4 < x < 3.

In interval notation this is: (-4, 3).

It is clear that T lies on the perpendicular bisector of NP. See the explanation below.

<h3>What is the explanation for the assertion above?</h3>

Given that M (X,Y) is the midpoint of NP

X thus = (5+1)/2

= 3

Y = (7+1)/2

= 4

Hence, we have M (3,4)

Consequent on the above:

Slope TM (m') = (4-2) / (3-6) = - 2/3

Slope of NP (m) = (7-1) / (5-1) = 6/4 = 3/2
M' = -1/m

Hence

TM ⊥ NP; and NP ⊥ TM

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an A

Alex777 [14]

Complete question :

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.

Construct a confidence interval for the mean jump height of gray kangaroos.

Answer:

(271, 301)

Step-by-step explanation:

Given that:

Mean (x¯) = 286

Margin of Error = 15 inches

The confidence interval :

(Mean - Margin of Error), (mean + margin of error)

(286 - 15), (286 + 15)

(271, 301)

Hence confidence interval equals : (271, 301)

a department store holds a year-end clearance sale that includes a 19.8% discount on cosmetics. find the sale price of a bottle

Ivan

The sale price of a bottle of perfume is $40.16 if its original price was 50.07%.

What is discount?

By paying a charge or fee, a debtor might purchase the right to postpone payments to a creditor for a predetermined length of time through the financial mechanism known as discounting. In essence, the party who is currently owing money purchases the right to postpone payment until a later time.

Let the original price of the perfume bottle is, $50.07

The sale on the cosmetics is 19.8%.

So, the discount on the perfume bottle is,

50.07 x 0.198 = 9.91368

Therefore, the sale price of perfume is,

$50.07 - $9.91368 = $40.15614

Hence, the sale price of perfume is, $40.16

Which equation demonstrates the multiplicative identity property?

12345 [234]

Answer:

(-3+5)(1)=-3+5

Step-by-step explanation:

The multiplicative identity is 1.

The multiplicative identity property days that, if you multiply a real number by 1, that result is the same real number.

This is demonstrated in option B of the given alternatives, where we have:

$( - 3 + 5)(1) = - 3 + 5$

The multiplication by did not change b the value.
