Answer:
C
Step-by-step explanation:
The inequality is x+2 > 2
x+2 >2 substract 2 from each side x+2-2 > 2-2x > 0x > 0 means that x is positive
so the graph must start from 0 and then should grow towrd the positive value
since we have x > 0 then 0 should be excluded
the graph that fits our solution is c where 0 is excluded

b)
5.2 × 7.7 = 40.04 cm²
Answer:
a) 24
b) 40.04
Step-by-step explanation:
a) Area of a rectangle: length x width
length = 8
width = 3
Plug these values into the equation above:
8 x 3 = 24

Let 16-4y=0
Substracting 16 on both sides
16-16-4y=-16

A car rental agency rents 210 cars per day at a rate of 27 dollars per day. For each 1 dollar increase in the daily rate, 5 fewer cars are rented. At what rate should the cars be rented to produce the maximum income, and what is the maximum income?
Answers
Answer:
x=7.5
Step-by-step explanation:
Rental: R(x)=(27+x) dollar per day
Number of cars rented: N(x)
=(210-5x)
Income: I(x) =(27+x)(210-5x)
=5670 - 135x + 210x-5x^2
=5670+75x-5x^2
The maximum will be achieved when the derivative of
I(x) =zero.
I(x)=5670+75x-5x^2
dI(x)/dx=75-10x=0
75-10x=0
75=10x
x=75/10
=7.5
x=7.5
x=7.5 is the rate at which the car will be rented to produce maximum income.
The maximum income could be derived by using x=7 or x=8
27+7=$34 per day
27+8=$35 per day
When x=7
I(x)=5670+75x-5x^2
=5670+75(7)-5(7)^2
=5670+525-5(49)
=5670+525-245
=5,950
When x=8
I(x)=5670+75x-5x^2
=5670+75(8)-5(8)^2
=5670+600-5(64)
=5670+600-320
=5950
Either x=7 or 8 will yield the same income

Instructions: Find the measurement of the angle indicated in the following parallelogram.
Answers
Answer:
∠T = 110°
Step-by-step explanation:
Angles in a parallelogram are supplementary. This means that angle T is a supplementary angle with angles U and S.
With this info, we can find ∠T by subtracting 70° from 180°
180° - 70° = 110°
∠T = 110°
The required angle T is 110°.
A parallelogram is given, angle s = 70, angle T to be determine.
Parallelogram is quadrilateral whose opposite sides are parallel and sum of the adjacent angles is 180°.
Here, in parallelogram the sum of the adjacent angle is 180. So,
T + S = 180
T + 70 = 180
T = 180 - 70
T = 110
Thus, the required angle T is 110°.

Carter is choosing clay for his pottery class. Clay is sold in three different-shaped solids at the craft store. The dimensions of each of these shapes is shown below. Find the amount of clay in each solid. Use 3.14 for Pi
After you found the amount for each solid, use them to answer this At the craft store discussed above, the clay cone is $12, the clay cylinder is $30, and the clay sphere is $28. Which is the best buy? Explain.
Answers
Answer: sphere
Step-by-step explanation:
For cone,
Radius = 9 in.
height = 12 in.
Volume = [tex]\dfrac{1}{3}\pi r^2h[/tex]
Then, Volume = [tex]\dfrac{1}{3}(3.14)(9)^2(12)=1017.36\ \text{cubic inches}[/tex]
For cylinder,
Radius = 9 in.
height = 12 in.
Volume = [tex]\pi r^2h[/tex]
Then, volume = [tex](3.14)(9)^2(12)=3052.08\text{ cubic inches}[/tex]
For sphere,
Radius = 9 in.
Volume = [tex]\dfrac{4}{3}\pi r^3[/tex]
Then, volume = [tex]\dfrac{4}{3}(3.14)(9)^3=3052.08\text{ cubic inches}[/tex]
For best buy, we require highest volume but lowest cost.
Thus, Volume of cone < Volume of cylinder and volume of sphere.
Volume of cylinder = volume of sphere.
But the cost of the sphere < cost of cylinder as $28<$30.
So, the sphere would be the best buy as it has the greatest volume but low cost.

Q1: How are rational exponents and radicals related? Q2: How can the average rate of change be identified for a function? Q3: How do linear and exponential functions compare as the domain increases?
Answers
Answer:
The answer is given below
Step-by-step explanation:
Q1: How are rational exponents and radicals related?
Rational exponents are exponents in fraction form. Radicals are roots (square root, cube root and so on).
The denominator of the rational exponent is the root which is the same as the radical.
Q2: How can the average rate of change be identified for a function?
The average rate of change is ratio of the change in output to the change in input values. The average rate of change for a function is the slope of the function.
It can be gotten by finding the first derivative of he function.
Q3: How do linear and exponential functions compare as the domain increases?
For linear functions as x increases, y also increases by the same amount (i.e rate of change is constant). For exponential function the rate of change increases by a factor known as the multiplier.

Write the equation of a line that is perpendicular to y=-2x/7+9 and that passes through the point (4,−6)
Answers
Answer:
y = (7/2)x -20
Step-by-step explanation:
The given line is in slope-intercept form, so you can read its slope from the equation.
y = mx + b . . . . . m is the slope; b is the y-intercept
y = -(2/7)x + 9 . . . . . . has slope -2/7
The perpendicular line will have a slope that is the negative reciprocal of this, so will be ...
m = -1/(-2/7) = 7/2
We can use this and the given point to write the equation in point-slope form.
y = m(x -h) +k . . . . . . line with slope m through point (h, k)
We have m = 7/2, (h, k) = (4, -6) so the equation is ...
y = (7/2)(x -4) -6
y = (7/2)x -20
John took all his money from his savings account. He spent $88 on a radio and 1/4 of what was left on presents for his friends. Of the money remaining, John put 4/11 into a checking account and the last remaining $420 was left to charity. How much money did John originally have in his savings account?
Answers
Answer:
$968
Step-by-step explanation:
x= the money John originally had in his savings account
The statement says that John spent $88 on a radio and 1/4 of what was left on presents for his friends. This means that the remaining money is 3/4 of the total amount minus the money spent on the radio:
3/4(x-88)
Then, it says that of the money remaining, John put 4/11 into a checking account and the last remaining $420 was left to charity. Since, he spent 4/11 of the remining 3/4(x-88), the remaining is 7/11 of that and that remaining is equal to $420 that was the money left at the end:
7/11(3/4(x-88))= 420
21/44(x-88)=420
21/44x-42=420
21/44x=462
x=968
According to this, the money that John originally had in his savings account was $968.
He spent $88 on a radio: 968-88= 880
1/4 of what was left on presents for his friends: 880/4= 220
880-220=660
Of the money remaining, John put 4/11 into a checking account: 660*(4/11)=240
the last remaining $420 was left to charity: 660-240= 420

In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JK=24 and JM=18, find JL.
Answers
Answer:
JL ≈ 32
Step-by-step explanation:
The triangle JKL has a side of JK = 24 and we are asked to find side JL. The triangle JKL is a right angle triangle.
Let us find side the angle J first from the triangle JKM. Angle JMN is 90°(angle on a straight line).
using the cosine ratio
cos J = adjacent/hypotenuse
cos J = 18/24
cos J = 0.75
J = cos⁻¹ 0.75
J = 41.4096221093
J ≈ 41.41°
Let us find the third angle L of the triangle JKL .Sum of angle in a triangle = 180°. Therefore, 180 - 41.41 - 90 = 48.59
Angle L = 48.59 °.
Using sine ratio
sin 48.59 ° = opposite/hypotenuse
sin 48.59 ° = 24/JL
cross multiply
JL sin 48.59 ° = 24
divide both sides by sin 48.59 °
JL = 24/sin 48.59 °
JL = 24/0.74999563751
JL = 32.0001861339
JL ≈ 32

Answers
Answer:
x = 5
∠L = 114°
∠ LMK = 31°
Step-by-step explanation:
In parallelogram, opposite sides are parallel and equal.
3x = 15
Divide both sides by 3
3x/3 = 15/3
x = 5
In parallelogram, opposite angles are equal
∠L = ∠J
∠L = 114°
In ΔJKM,
∠J + ∠JKM + ∠JMK = 180 {Angle sum property of triangle}
114 + ∠JKM + 35 = 180
149 + ∠JKM =180
∠JKM = 180 - 149
∠JKM = 31°
JK & ML are parallel and KM is transversal
Therefore, ∠ LMK = ∠JKM { oppoiste interior angles are congruent}
∠ LMK = 31°
Answer:
x = 5
∠L = 114°
∠ LMK = 31°
