Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
A) -1
B) -2
C) 1
D) 2
Answer:
D) 2
The average rate of change of f(x)
A(x) =2
Step-by-step explanation:
Step(i):-
Given that the function f(x) = x² - 3x -10
Given x =a = -5 and y = b = 10
The average rate of change of f(x)
[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]
Step(ii):-
f(x) = x² - 3x -10
f(-5) = (-5)² - 3(-5) -10 = 25+15-10=30
f(10) = (10)² -3(10)-10 = 100 -30 -10 =60
The average rate of change of f(x)
[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]
[tex]A(x) = \frac{60-30}{10-(-5)}= \frac{30}{15} = 2[/tex]
A(x) =2
Mr. Shaw wants to replace the flooring his family room. The floor has an area of 262.8 square feet. If the room is 18 feet long, how wide is it? Justify your procedure.
Answer:
14.6
Step-by-step explanation:
The area of a rectangle is area=length*width
so we can substitute the numbers here, 262.8=18w
divide 262.8 by 18 to isolate the variable.
You get 14.6.
The width is 14.6.

Round off 54.3223 to 1 decimal place
Answer:
54.3
Step-by-step explanation:
since it is mentioned 54.3223, then u should see the two decimal places as they are asking to round it off to one decimal place. so we should see 54.32 only
if the second decimal is less than 5, then you should write the first decimal as it is like the above mentioned question (remember we are only supposed to mention one decimal place)
but if it is 5 or more, then you should move the first decimal to the next number. for example, 54.678. for this you should write 54.7 because the second decimal is more than 5
if they are asking to round it off to 3 places then you should see 4 decimal places

a triangle has side length of 10 inches, 24 inches, and 26 inches. Is the triangle a right triangle?
Can someone help me please
Answer: D.) y = 2x + 1
Step-by-step explanation:
in slope-intercept form, y = mx + b, m is the slope, Rise/Run
The difference in y-values, rise, increases by 2 for every increase of 1 in x-values, the run.
2/1 is the slope
m = 2
b is the y-intercept
To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:
9 = 4(2) + b
9 = 8 + b
1 = b
Rewrite the equation with the values calculated for m and b. Keep y and x
y = 2x + 1
What number is the same as distance from 0 on a number line as 1 1/2
Answer: What is the distance from 0 on a number line called?
The distance between a number's place on the number line and 0 is called the number's [absolute value]. To write the absolute value of a number, use short vertical lines (|) on either side of the number.

Allison invest $5000 in CD at an interest rate of 2%. What will her total be worth at the end of 3 years?
Answer:How much interest will I earn in a CD? It depends on the interest rate the bank offers and how long the CD's term is. Here's an example: $5,000 invested in a 3-year CD with a 0.80% APY would earn about $120 by the end of the term.

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?
Answer:
The jet will cover 2585 miles in 11 hours.
Step-by-step explanation:
Given that:
Distance travelled by jet in 2 hours = 470 miles
Speed of jet = [tex]\frac{Distance}{Time}[/tex]
Speed of jet = 470/2
Speed of jet = 235 miles per hour
Time = 11 hours
Distance travelled in 11 hours = Speed * Time
Distance = 235 * 11
Distance = 2585 miles
Hence,
The jet will cover 2585 miles in 11 hours.

6x-18=54 what does the x represent
Answer:
x=12
Step-by-step explanation:
I attached a picture for the steps
Simplifying
6x + -18 = 54
Reorder the terms:
-18 + 6x = 54
Solving
-18 + 6x = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 6x = 54 + 18
Combine like terms: -18 + 18 = 0
0 + 6x = 54 + 18
6x = 54 + 18
Combine like terms: 54 + 18 = 72
6x = 72
Divide each side by '6'.
x = 12
Simplifying
x = 12
Final Result: 12
(-1,4) and ( 1, -1) Find the distance between each pair of points
Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
We are basically trying to find the hypotenuse of the triangle.
The distance between the x is 2, and the distance between the y is 5, which makes a length and a width.
Pythagrenum theorem: a^2+b^2=c^2
2^2 is 4, 5^2 is 25.
4+25 is 29.
The distance is [tex]\sqrt{29}[/tex].
What is the least common denominator? *
1 2
and
5 3
Answer:
To get the Least Common Multiple (LCM) of 12 and 53 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
12: 223
53: 53
LCM: 22353
The Least Common Multiple (LCM) is: 2 x 2 x 3 x 53 = 636

Answer:
SAS Congruency (see below)
Step-by-step explanation:
First, prove the two triangles congruent:
You should know that ∠HKL ≅ ∠MKL because of Vertical Angles Congruence Theorem because they're vertical angles.
If it's already given that HK ≅ MK and JK ≅ LK, then you can clearly see that you can use the SAS Postulate to prove ΔHKL ≅ ΔMKL.

As a estimation we are told £3 is €4. Convert £25.50 to euros €
Answer:
£34
Step-by-step explanation:
→ Find how euros is in a pound
£3 = €4
£1 = €1.33
→ Multiply the euro by 25.50
1.33333 × 25.50 = £34
Answer:
€34
Step-by-step explanation:
First you'll want to find out how much £1 is.
Since we know £3 is equal to €4 we can:
divide £3 by 3 = £1divide €4 by 3 = €1.33So, £1 = €1.33
With this in mind, we can find out what £25.50 is:
£1 x 25.50 = £25.50€1.33 x 25.50 = €34Therefore, £25.50 = €34
