The function h is defined by
h(x)=x²-2.
Find h(2z)
Answer:
[tex]h(x) = {x}^{2} - 2 \\ h(2z) = {(2z)}^{2} - 2 \\ = 4 {z}^{2} - 2 \\ = 2( {2z}^{2} - 1)[/tex]
A car depreciates by 5% in a year. If the initial value was $10,000, what is its value after a year?
Answer: $9,500
Step-by-step explanation:
If the value of the car depreciates by 5% in a year it means that the value of the car reduced by 5%.
First find the 5%:
= 5% * 10,000
= $500
Subtract this from the initial value to find the value after a year:
= 10,000 - 500
= $9,500
Answer:
$ 9500
Step-by-step explanation:
From the question given above, the following data were obtained:
Initial value = $ 10000
Depreciation rate = 5%
Value after one year =?
Next, we shall determine the depreciation value. This can be obtained as follow:
Initial value = $ 10000
Depreciation rate = 5%
Depreciation value =?
Depreciation value = Initial value × rate
Depreciation value = 10000 × 5%
Depreciation value = 10000 × 5/100
Depreciation value = $ 500
Finally, we shall determine the value of the car after one year. This can be obtained as follow:
Initial value = $ 10000
Depreciation value = $ 500
Value after one year =?
Value after one year = Initial value – Depreciation value
Value after one year = 10000 – 500
Value after one year = $ 9500
Therefore, the value of the car after one year is $ 9500

Poor jocelyn! She was running a race and at the 9 1/4 marker, she stumbled and twisted her ankle. If she was only 3/8 of the way, how long was the race?
Answer: 24 2/3
Step-by-step explanation:
Let the total distance of the race be represented by x.
Therefore, based on the information given, we can form an equation which will be:
3/8 of x = 9 1/4
3/8x = 9 1/4
0.375x = 9.25
x = 9.25/0.375
x = 24.67
The distance of the race is 24 2/3

George has to pay $30 in taxes for every $100 that he earns. Last summer, he earned $3680. How much did he pay in taxes?(must use direct proportion) pleaseee help
Answer:
$1,140
Step-by-step explanation:
Step 1: Set up a fraction and solve (We are doing this to make it simpler to solve. So let us use "x" to represent how much he paid in taxes. )
[tex]\frac{30}{100}=\frac{x}{3680}[/tex]
Step 2: Solve; Divide the given values (The given values are 100 over 30. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.3 once divided)
[tex]\frac{30}{100}[/tex]
Cancel both zeros
[tex]\frac{30}{100}\\\\= \frac{3}{10}[/tex]
Divide
[tex]\frac{3}{10}\\\\= 3 \div 10\\\\= 0.3[/tex]
Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)
[tex]0.3\\\\0.3 \times 3680\\\\=1140[/tex]
Therefore, George paid 1140 dollars in taxes last summer.
find the value of X. Round to the nearest tenth. Show or explain your answer.Please I need this answered ASAP.
Answer:
c=21.6
Step-by-step explanation:
First, find the last angle of the triangle.
The sum of all the angles in a triangle is 180 degrees.
A+90+37=180
A=53
Now find x
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(B)=adj/hyp
rewrite as
c=a/cos(B)
c=17.3/cos(37)
c=21.66194688

f(x) = square root of (-7 + 2) - 6
f(x) =square root of (-5) - 6
f(x) = 2.236 = 2.2 - 6
f(x) = -3.8
F(x) = √x+2 -6
F(x) = √7+2 -6
F(x) = 3-6
F(x) = -3
At a lunch shop, a hamburger costs $2.99 and a hot dog costs $2.50.
How much more does a hamburger cost than a hot dog?
To find the difference subtract the price of the hot dog from the price of the hamburger:
2.99 - 2.50 = 0.49
The hamburger cost $0.49 more than the hot dog.
Sophie caught twice as many fish as her
dad. If her dad caught Ffish, how many
fish did Sophie catch?
A. F + 2
B. F-2
C. Fx 2
D. F/2
Answer:
C. F × 2
Step-by-step explanation:
Twice as many infers multiplication. Since Sophie caught twice as many as her dad, then we would multiply the number of her dad's caught fish by 2. The question states her dad's caught fish is represented by variable F so it would be:
F × 2

Jennifer invested $400 at 6% interest compounded continuously. Write a model m(t) that represents the money in Jennifer's account in t years. A. B. How much money is in Jennifer's account after 5 years? Round to the nearest cent. C. Approximately when will Jennifer have $800 in her account? Round to the nearest tenth of a year.
Answer:
11.5 years
Step-by-step explanation:
Given data
Principal= $400
Rate= 6%
For the compound interest at time t, the expression is given as
A= P(1+r)^t
Substitute
A= 400(1+0.06)^t
A=400(1.06)^t
B. How much money is in Jennifer's account after 5 years
put t= 5
A=400(1.06)^5
A=400*1.338
A=$535.2
C. Approximately when will Jennifer have $800 in her account
A=$800
P=$400
r=6%
t= ln(A/P)/r
t= ln(800/400)/0.06
t= ln(2)/0.06
t= 0.6931/0.06
t=11.551
Hence the time is about 11.5 years

Step-by-step explanation:
A sunflower grew 7 yards during the first week after it was planted. What is the height of the total sunflower in feet?
Answer:
21 feet
Step-by-step explanation:
Remember to get feet to yards, multiply the feet by 3 because there are 3 feet in one yard
in this case 7 × 3 = 21
And additionally to get yards to feet, divide by three because 1 yard = 3 feet

Factorize completely 3ac+6ab-15a
Answer:
3a(c + 2b - 5)
Step-by-step explanation:
Step-by-step explanation: The greatest common factor for the 3 terms here is 3a so factor out a 3a and what we're left with inside the parentheses is each of the terms in the original polynomial divided by 3a.
So we have 3a(c + 2b - 5) which is our final answer.
someone help me find what is m
Answer:
measure of angle F= 109 degrees
Step-by-step explanation:
I believe by m you are solving for angle F. So, angle H =71 degrees. GF and HI are parallel. In order to find angle G, Take the supplementary of 71 degrees, so 180-71 = angle G =109 degrees. Because GH and FI are congruent, the angles should be same across the shape, so angle I 71 degrees. Quadrilateral has a total of 360 degrees, so, 360-71-109-71=109 degrees. In general, angke G would equal angle F because of the trapezoid properties that take place when both bases are parallel and two of the sides are congruent, the trapezoid is an isosceles trapezoid

To find the surface area of the pyramid, in square inches, Vikram wrote (33.2) (34.2) + 4 (one-half (34.2) (28.4)). What error did Vikram make? He used the same expression for the area of all four lateral faces. He used the wrong expression to represent the area of the base of the pyramid. He used the wrong value as the height when he found the area of the lateral faces. He used an expression for surface area that only finds the total area of three faces.
Answer:
B. He used the wrong expression to represent the area of the base of the pyramid.
Step-by-step explanation:
Given
See attachment for pyramid
[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]
Required
Vikram's error
The surface area of a square pyramid is:
[tex]Area = Base\ Area + 4 * Area \triangle[/tex]
Where
[tex]Base\ Area = Length * Length[/tex]
[tex]Base\ Area = 34.2 * 34.2[/tex]
[tex]4 * Area \triangle = 4 * \frac{1}{2} * Base * Height[/tex]
[tex]4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4[/tex]
So:
[tex]Area = Base\ Area + 4 * Area \triangle[/tex]
[tex]Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4[/tex]
By comparing the calculated expression with
[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]
Option (b) is correct
