2. Write two numbers that are opposites and each more than 6 units away from 0.

Answers

Answer:

-7, 7

Step-by-step explanation:

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

Evaluate f(x) = -2x - 5 for x = 3.

A. 1

B. 11

C. –6

D. –11

Answers

I think the answer is d. -11

Explanation:

Replace the variable x with 3 in the expression.
f(3)=-2•3-5

Multiply -2 by 3
f(3)=-6 -5

Subtract 5 from -6
f(3)= -11

Then the answer should be -11.

Find the measure of the indicated arc in circle O. Use pic for more

Answers

Note that m∡DC = 44°.

How did we arrive at this ?

Note that the measure of the central angle and the arc it creates are the same.

Thus, since ∠DOC creates ∡DC

Hence, ∡DC = 44°

Note that an inscribed angle in geometry is the angle created in the inside of a circle when two chords meet on the circle.

It may alternatively be defined as the angle formed by two given points on a circle at a specified position on the circle. one inscribed angle is formed by two circle chords that share one endpoint.

Answers

Answer:

[ Because those two numbers are removed you need to reduce the number of terms to 98. ]

☆Solution☆

N=100

Mean=65

(Wrong Numbers=40,50)

Now,

Mean=Sum/No. of items

or,65=Sum/100

▪Sum=65×100=6500

After removing the unnecessary numbers,

New Sum=6500-40-50=6410

New no.of terms(N)=100-2=98

Now,

New Mean=New Sum/New N

=6410/98

Answers

Answer:

a₃₅ = 182

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 17 - 12 = 22 - 17 = 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 12 and d = 5 , then

a₃₅ = 12 + (34 × 5) = 12 + 170 = 182
