Answer:
[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)[/tex]
Apply the exponent rule:
[tex]a^b\cdot \:a^c=a^{b+c}[/tex]
so the expression becomes
[tex]\left(3x^2\right)\:\left(5x^8\right)\:\left(6x^5\right)=3\cdot \:\:5\cdot \:\:6x^{2+8+5}[/tex]
Add the exponent numbers: 2+8+5=15
[tex]=3\cdot \:5\cdot \:6x^{15}[/tex]
Multiply the numbers: 3×5×6=90
[tex]=90x^{15}[/tex]
Therefore, we conclude that:
[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]
1. Triangle STU with vertices S(-4, 2) T(5, -1),
and U(-2,-2): (x, y) → (x - 1, y-5
I need help ASAP!!!
Answer:
S’ (-5,-3)
T’ (4,-6)
U’ (-3,-7)
Step-by-step explanation:
Basically, we want to apply the given transformation rule of the axes to get the coordinates of the images
The rule is that we subtract 1 from the x-coordinates and also subtract 5 from the y-coordinates
Thus, we proceed as follows;
S’ = (-4-1, 2-5) = (-5,-3)
T’ = (5-1, -1-5) = (4,-6)
U’ = (-2-1,-2-5) = (-3,-7)

Q2
A car travels at 72 mph for 3 hours and 40 minutes.
How far has it travelled?
miles
[2]
8
Answer:
264 miles
Step-by-step explanation:
Let's convert 3 hours and 40 minutes into hours first.
Recall that 1 hour = 60 minutes.
Therefore 40 minutes = 40/60 hours = 2/3 hours.
The car travelled 3 and 2/3 hours in total.
Recall that distance = speed times time.
The car has travelled 72 x 3 2/3 miles = 264 miles.

A circle has a radius of 4.2 cm.
Work out the length of the circumference.
Give your answer to 1 decimal place.
Step-by-step explanation:
r=4.2
cicumference of circle =2Πr=2×3.14×4.2=26.3
The circumference of the circle will be 26.4 cm.
What are the properties of the circle?The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.
Given, A circle has a radius of 4.2 cm.
From the general formula of the circumference of the circle:
Circumference of the circle = 2*pi* radius
in our case,
Circumference of the circle = 2*pi *4.2
Circumference of the circle = 26.389 cm
Therefore, The circumference of the circle will be 26.4 cm.

student borrows $65,000 for business school at 8.5% stated annual interest with monthly repayment over 8 years. Consider this as a loan with no payments or interest during school so that the problem structure is equivalent to a standard loan received one period before the first payment. Suppose that to better match expected student salary growth over time, the loan is structured as a growing annuity with each monthly payment growing by 0.2% compared to the previous monthly payment. How much is the first monthly payment?
Answer:
[tex]First\ monthly\ payment= $858.69[/tex]
Step-by-step explanation:
From the Question we are told that
Borrows $65,000
Annual interest 8.5%
Monthly repayment over 8 years
Generally PV of annuity with growth is mathematically represented as
where PV is present value
PV of annuity with growth X= [tex](P/ (r-g)) * (1- ((1+g)/(1+r))^n)[/tex]
[tex]\frac{P}{\frac{8\%}{y12-0.2\%} } *(1-((1+0.2\%)/(1+8.5\%/12))^(^8^*^1^2^)^)=65000[/tex]
[tex]196.7213115P* 0.384791918=65000[/tex]

(7x +33)
(11 X+21)
E
O A. 5
B. 8
C. 6
O D. 7
Answer: x = 7
Step-by-step explanation: All the angles of a parallelogram add to 360°
Any two of the consecutive angles add to 180°
Using that information, we can create an equation with the angle measurements given:
(7x + 33) + (11x + 21) = 180 . Combine like terms:
7x + 11x + 33 + 21 =180
18x + 54 = 180 . Subtract 54 from both sides
18x = 126 Divide both sides by 18
x = 7

15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from Con
AB is 4.5 cm find its area.
Answer:
32.40cm²
Step-by-step explanation:
Given the parallelogram ABCD ;
AB = 7.2
Perpendicular from C on AB = 4.5
FOR a parallelogram, ABCD ;
AB = CD = 7.2 cm
Perpendicular from C on AB = height, h of the parallelogram = 4.5cm
Area of a parallelogram = length base * height
Area of a parallelogram = 7.2 cm * 4.5cm
Area of parallelogram = 32.40cm²

Sweety’s mother is 12 years more than twice Sweety’s age. After 8 years, she will be 20 years less than three times Sweety’s age. Find Sweety’s age and Sweety’s mother’s age?
Answer:
Sweety's age = 16 years and Sweety’s mother’s age = 44 years
Step-by-step explanation:
Let Sweety's age is x.
Sweety’s mother age = 12+2x
After 8 years,
Sweety's age = x+8
Sweety’s mother age = 12+2x+8
Since Mother's age will be 20 years less than three times my age.
2x+20 = 3(x+8)-20
2x+20=3x+24-20
2x+20=3x+4
Taking like terms together,
20-4=3x-2x
x = 16
Sweety's age = 16 years
Sweety’s mother’s age = 12+2x
= 12+2(16)
= 12 + 32
= 44 years
Hence, Sweety’s age and Sweety’s mother’s age is 16 years and 44 years respectively.
