Answer:
1. Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
2.Exact solution x = -0.376
Step-by-step explanation:
Solution:
First we have to write the Expanded Form of [tex]a^{2} . b^{3}[/tex], Let's do it.
1) [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
Hence,
Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
2) [tex]4^{5x} = 3^{x-2}[/tex]
Now, we have to find out the exact solution of the above equation:
In order to equate the exponents, we need to make sure the bases are same. Or we simply can use logarithm to solve the above equation.
So,
We are using logarithm to solve this equation.
Let's break this down:
[tex]4^{5x} = 3^{x-2}[/tex]
Taking log on both sides.
log[tex]4^{5x}[/tex] = log[tex]3^{x-2}[/tex]
[tex]5xlog(4)[/tex] = [tex](x-2)log(3)[/tex]
Dividing both sides by log(4)
[tex]5x[/tex] = (x-2) [tex]\frac{log(3)}{log(4)}[/tex]
value of log(3) = 0.4771
value of log(4) = 0.6020
[tex]5x[/tex] = (x-2) [tex]\frac{log(0.4771)}{log(0.6020)}[/tex] =
5x = (x-2)0.792
5x = 0.792x - 1.584
by rearranging the equation, we get:
0.792x - 5x = 1.584
x(0.792 - 5) = 1.584
x(-4.208) = 1.584
x = -1.584/4.208
x = -0.376
Exact solution x = -0.376
10. The Johnson family purchased a new television that had a 62 inch diagonal. The height of the television was 30 inches. Approximately how wide is the new television? show work
Answers
Answer:
Width = 54.3 inches
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
Width² + Height² = Diagonal²
From the above question
Width= ??
Height = 30 inches
Diagonal = 62 inches
Width² + 30² = 62²
Width² = 62² - 30²
Width = √62² - 30²
Width =✓2944
Width = 54.258639865 inches
Approximately
Width = 54.3 inches
Hence, the new television was 54.3 inches wide.

Melissa is 13 years old. Becky is 12 years old. Daniel is 10 years old. Melissa, Becky and Daniel share £42 in the ratio of their ages. Becky decided to save a third of her share. How much will Becky have to spend?
Answers
Answer: Becky will have to spend £ 9.6 .
Step-by-step explanation:
The ratio of their ages will be:
Melissa : Becky : Daniel = 13 : 12 : 10
Total amount share = £42
Share of Becky = [tex]\dfrac{12}{12+13+10}\times42[/tex]
[tex]=\dfrac{12}{35}\times42\\\\= 14.4[/tex]
Hence, Becky's share = £14.4
Becky decided to save a third of her share.
Then, Amount she spend = [tex]14.4-\dfrac13 \times 14.4[/tex]
[tex]=14.4-4.8\\=9.6[/tex]
hence, Becky will have to spend £ 9.6 .

Frequency=825
ThereforeThe frequency in this interval is equal to:825
The frequency in this interval is equal to 825.
Given
A population is of size 5,500 observations.
When the data are represented in a relative frequency distribution, the relative frequency of a given interval is 0.15.
Frequency;The frequency is defined as the product of population size and relative frequency interval.
The following formula is used to calculate frequency in this interval is;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\Frequency= 5500\times 0.15\\\\Frequency= 55\times 15\\\\Frequency= 825[/tex]

Translate the shape by the vector { -1 }

Answers
Answer:
Step-by-step explanation:
Coordinates of the given rectangle are,
A → (3, 3)
B → (6, 3)
C → (6, 1)
D → (3, 1)
Translation of the given rectangle by the vector [tex]\binom{-1}{5}[/tex] means, shifting of rectangle by 1 unit to the left and 5 units up.
So the rule which defines the translation of the vertices by the given vector is,
(x, y) → (x - 1, y + 5)
By this rule, after translation vertices of image rectangle will be,
A(3, 3) → A'(2, 8)
B(6, 3) → B'(5, 8)
C(6, 1) → C'(5, 6)
D(3, 1) → D'(2, 6)
Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill. If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk?
Answers
Given :
Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.
To Find :
If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.
Solution :
Time taken to walk one mile uphill is :
[tex]t_1 = \dfrac{1}{3}\ hours[/tex]
Time taken to walk two mile on flat land( one on going and one or returning ) is :
[tex]t_2 = \dfrac{2}{4}\ hours\\\\ t_2 = \dfrac{1}{2}\ hours[/tex]
Time taken to walk one mile downhill is :
[tex]t_3 = \dfrac{1}{5}\ hours[/tex]
Total time taken :
[tex]T = t_1 + t_2 + t_3 \\\\T = \dfrac{1}{3} + \dfrac{1}{2}+\dfrac{1}{5}\\\\T = \dfrac{10 + 15 + 6}{30} \\\\T = \dfrac{31}{30}\ hours = \dfrac{31}{30}\times 60 \ minutes\\\\T = 62\ minutes[/tex]
Therefore, time taken un 62 minutes.
