Answer:
They are not equivalent.
Step-by-step explanation:
Before we solve the question, we need to know that from the laws of indices:
A^x x A^y = A^(x+y).
7 to the power of 8th power means 7^8
7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.
7 to the power of 3rd power means 7^3
7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.
Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.

David has earned the following test
grades: 89, 96, 99, 85. What is the
grade David has to earn on his 5th test to maintain a test
average of 90?
Answer:
81
Step-by-step explanation:
Required average= 90
let the required grade be x
Average= Sum of n numbers
90= 89+96+99+85+x divide by 5
450= 369+x
x = 450-369
x=81

Please write the function(x) from the given rules:a. Twice the input value plus three. B. The input value minus five. C. To get the output, multiply the input by two, then add four.
Answer:
A) f(x) = 2x + 3
B) f(x) = x - 5
C) f(x) = 2x + 4
Step-by-step explanation:
To find - Please write the function(x) from the given rules:
A) Twice the input value plus three.
B) The input value minus five.
C) To get the output, multiply the input by two, then add four.
Proof -
Let us assume that the input = x
The output = f(x)
Now,
A)
f(x) = 2x + 3
B)
f(x) = x - 5
C)
f(x) = 2x + 4

question
(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!
Answer:
(60-5.8) ÷ 5 - 3² = 1.84 (approx)
Step-by-step explanation:
(60-5.8) ÷ 5 - 3²
First simplify the numbers inside the bracket.
(60-5.8) = 54.2
Now, the equation is in the form of,
54.2 ÷ 5 - 9
Put 54.2 ÷ 5 in a bracket for easy calculation.
(54.2 ÷ 5) - 9
Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84
Subtract 9 from 10.84
10.84 - 9
You will now get the answer as,
1.84 (approx)

Answer:
y=-2x+1
Step-by-step explanation:
First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2. Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.
Answer:
Step-by-step explanation:
The slope intercept form of a line is
y=mx+b, where m=slope and b= y intercept
The slope of a line is defined as
m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)
m=(-9-(-5))/(5-3)
m=-4/2
m=-2, so our line is now
y=-2x+b, using point (3,-5) we can now solve for b
-5=-2(3)+b
-5=-6+b
1=b so the completed line is
y=-2x+1

[tex] \sqrt{ {4 a}^{2} + {12a}^{2} } [/tex]
Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
[tex] \sqrt{ {16a}^{2} } [/tex]
2) Use this rule:
[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]
[tex] \sqrt{16} \sqrt{ {a}^{2} } [/tex]
3) Since 4 × 4 is 16, the square root of 16 is 4.
[tex]4 \sqrt{ {a}^{2} } [/tex]
4) Simplify.
[tex]4a[/tex]
Therefor, the answer is 4a.

The diagram shows a solid metal cuboid.
The areas of three of the faces are marked on
the diagram.
The lengths, in cm, of the edges of the cuboid
are whole numbers.
The metal cuboid is melted and made into cubes.
Each of the cubes has sides of length 2.5 cm.
Work out the greatest number of these cubes that can be made.
You must show your working.
Answer:
6 cubes
Step-by-step explanation:
Considering the given cuboid, it can be deduced that;
length of the cuboid = 7 cm
width of the cuboid = 3 cm
height of the cuboid = 5 cm
Thus,
volume of the cuboid = length x width x height
= 7 x 3 x 5
= 105 cubic centimetres
The cubes has sides of length 2.5 cm.
volume of each cube = length x width x height
= 2.5 x 2.5 x 2.5
= 15.625 cubic centimetres
The greatest number of cubes that can be made = [tex]\frac{105}{15.625}[/tex]
= 6.72
The greatest number of cubes that can be made from the cuboid is 6.

The picture shows the letter H that is on a store sign.
3 in.
9 in.
3 in.
3 in.
3 in.
3 in.
What is the area of this letter H? Enter the answer in the box.
square inches
Answer:
[tex]63in^2[/tex]
Step-by-step explanation:
To find the area of the larger, complex figure, divide the shape up into smaller figures, solve for the area of each smaller part and then add up the answers to find the total area. The figure can be divided into two rectangles and a square.
The two rectangles are congruent, their dimensions are the following,
9in x 3in
The area of the square is the following,
3in x 3in
To find the area of both of these figures, one uses the formula,
[tex](length)(width)[/tex]
Substitute in each dimension and solve for the total area by adding up the results,
[tex]((9)(3))+((9)(3))+((3)(3))\\\\=(27)+(27)+(9)\\\\= 63[/tex]
The radius of a circular plate is 7 inches.
Find it's area.( use π= 3.14 )
Round to the nearest hundredth
Answer:
153.94 in²
Step-by-step explanation:
The equation for Area is
Area = πr²
Plugging in the value for the radius into r, it will be
(note, r means radius)
Area = π(7)²= 49π ≈ 153.94
The units is -> in² so add that in the end
for the arthritic sequence 5,9,13,17,21,... how many terms would you need to get to 129
9514 1404 393
Answer:
32
Step-by-step explanation:
The first term is 5 and the common difference is 9-5=4, so the n-th term is ...
an = a1 +d(n -1)
an = 5 +4(n -1) = 4n +1
Then the term number for the term 129 is ...
129 = 4n +1 . . . . . put the given value in the formula
128 = 4n . . . . . . . subtract 1
32 = n . . . . . . . . . .divide by 4
The 32nd term is 129.

The question is asking, which percentage would Darian most likely receive if he had studied for 9 hours.
The line of best fit would be used to determine the percentage he would most likely score based on the amount of hours he studied
Looking at the line of best fit we notice that at 9 hours Darian would most likely score a 78% on the test
Thus the answer is C

The question want you to find the graph that has a constant rate of change and has a y intercept of (0,0) so essentially
The question is asking "which graph best represents a proportional relationship."
If a relation is proportional it would have a straight line and it would go through the origin (0,0)
Looking at C we notice that the line is straight ( meaning it has a constant rate of change) and it also goes through the origin therefore C is your answer
