Answer 1

Answer:

Step-by-step explanation:

6-3=3 then power of 2 which is 9 then plus 1

Answer 2

Answer:

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C

Answer:

This is false. Lines will be congruent if they have the same length, which is not the case in all situations.

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.

earned for the period was
$450, what was the interest
rate?
A=P+Prt

Answers

Answer:

r = 0.05 or 5%

Step-by-step explanation:

450 = 9000 · r

450/9000 = r

r = 0.05 or 5%

Answer:

∠A = 126°

Step-by-step explanation:

Supplementary angles are angles that add up to equal 180°

Given that ∠B = 54°, we can subtract 54° from 180°.

180° - 54° = 126°

∠A = 126°

Step-by-step explanation:

There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)

There are 10 games, so 20/10 = 2 = mean

Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5

Classify the object with the given side lengths as acute, obtuse, right, or not a triangle.
16, 21, 28
Right
Acute
Obtuse
Not a triangle

Answers

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Hope it helps

y-5x-2 ... Show your work.
A) (-4,-22)
B) (4; 6)
C) (-4; 6)
D) (4;18)
no links and pls show ur work

Answers

I’m not sure if you mistyped but if you meant y=5x-2 then here is your answer:

So the equation is y=mx + b

-2 is your b meaning that it is your y intercept so you can plot it on the y axis (0,-2)

Then your slope is 5. Since your slope is positive, in order to go to the left side you can change both the denominator and numerator into negatives. So 5/1 = -5/-1

Slope = rise/run

So each time you go down 5, you go to the left once. So if you go to -4, then you will have to go down 4 times as well so 4 x 5 = 20, so you go down 20 points. You are already at (0,-2) so if you go down 20 points then you are at (-4,-22)

Therefore the correct answer is (-4,-22)

what is the HCF of 3000 and 525 answer with process

Answers

Answer:

The HCF is 75

Step-by-step explanation:

Here, we want to get the highest common factors of the two numbers

To do this, we have to write the numbers as the product of their prime factors

We have;

3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5

525 = 3 * 5 * 5 * 7

now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers

This represents the highest common factor of the two numbers

and that is 75

The candle fell from her nightstand and dropped onto the mattress where she slept. The mattress caught fire and Kate was severely burned. The mattress was a cheap no-frills model. It had been treated with some chemical additives to make it partially flame-resistant, but only to the extent of slowing the speed at which the fabric caught fire. It is possible to make mattresses fully flame-proof, but the process is an expensive one, so expensive that it would have taken the price of this mattress out of the "budget" range. The mattress bore a label indicating "flame resistant." During a discussion with the sales manager Kate asked about whether it was safe, and indicated she sometimes kept a candle by the bed. The sales manager said it was "the best mattress on the market." Kate wants to file a lawsuit against United Mattress Co. Can Kate sue based on negligence? Can Kate sue based on breach of warranty?
