Answer:
a = 2
b = 4
c = 8
Step-by-step explanation:
Remember the relationship:
[tex](a^{x})^{y} = a^{x*y}[/tex]
First, in "a" we have:
a) [tex]8^{1/3} = \sqrt[3]{8} = 2[/tex]
then in the next ones, we can use the result that we obtained in the part a:
b) [tex]8^{2/3} = (8^{1/3})^2 = (2)^2 = 4[/tex]
Now we can do exactly the same in c:
c) where first we need to know that:
2*2*2*2 = 4*4 = 16
then:
2^4 = 16
then:
[tex]\sqrt[4]{16} = 16^{1/4} = 2[/tex]
Now let's solve the problem:
[tex]16^{3/4} = (16^{1/4})^3 = (2)^3 = 2*2*2 = 8[/tex]

Answer:
The solution x > 10 can be represented in two ways such as:
Interval Notation: (10, ∞)Inequality Notation: x > 10Step-by-step explanation:
Let 'x' be the solution to the inequality
From the given line, it is clear that
x > 10
It means the value of x is greater than 10, which means the solution contains all the positive real numbers greater than 10.
From the number line, it is clear that the number line would include all the numbers on the right-hand side of the 10 number.
The number 10 is not included; thus the number line indicates an open circle on 10, meaning 10 is not include in the solution.
Thus, the solution x > 10 can be represented in two ways such as:
Interval Notation: (10, ∞)Inequality Notation: x > 10Pls help due ASAP and show workings pls
Answer:
The coordinates of point B are: (29,-15)
Option D is correct option.
Step-by-step explanation:
Endpoint of diameter of a circle = A(5,7)
Centre of circle = P(17,-4)
We need to find coordinates of other endpoint of diameter of a circle i.e. B
The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
We are given coordinates of centre (midpoint) P(17,-4)
and A (5,7) x₁=5, y₁=7
We need to find Point B i.e. (x₂,y₂)
Putting values and finding point B
[tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\\(17,-4)=(\frac{5+x_2}{2}, \frac{7+y_2}{2})\\We\:can\:write:\\17=\frac{5+x_2}{2}\:and\: -4=\frac{7+y_2}{2}\\17\times 2=5+x_2\:and\: -4\times 2=7+y_2\\34=5+x_2\:and\: -8=7+y_2\\34-5=x_2\:and\: -8-7=y_2\\x_2=29\:and\: y_2=-15[/tex]
so, we get: x₂ = 29 ,y₂ = -15
The coordinates of point B are: (29,-15)
Option D is correct option.

Expression is a set of numbers, variables, and mathematical operations. The standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As the expression is given to us (-7x + 5) - (2x² – 8x + 6), in order to simplify the problem we need to open the brackets. therefore, the expression can be solved as,
[tex](-7x + 5) - (2x^2 - 8x + 6)\\\\= -7x + 5 - 2x^2 + 8x - 6\\\\ = -2x^2+8x-7x-6+5\\\\=-2x^2 + x - 1[/tex]
Hence, the standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.

Answer:
A scale factor of 4in to 5in should be used
Step-by-step explanation:
Given
[tex]Original\ Measurement = 4.5\ in[/tex]
[tex]Scale\ Measurement = 3.6\ in[/tex]
Required
Determine the scale to use
The scale to use can be represented as:
[tex]Scale = Scale\ Measurement : Original\ Measurement[/tex]
This gives:
[tex]Scale = 3.6\ in : 4.5\ in[/tex]
Divide by 0.9
[tex]Scale = \frac{3.6}{0.9}\ in : \frac{4.5}{0..9}\ in[/tex]
[tex]Scale = \frac{3.6}{0.9} : \frac{4.5}{0.9}[/tex]
[tex]Scale = 4 : 5[/tex]

Arianna's little brother loves playing with bouncy balls. For his birthday, Arianna buys him 3 bouncy balls for $0.65 each. She hands the cashier a five-dollar bill. How much change should Arianna receive?
Answer:
Arianna should receive $3.05 in change.
Step-by-step explanation:
In order to find the answer, you have to find the cost of the three balls by multiplying the cost per ball for the number of balls and then, you have to subtract this amount from five to find the change Arianna should receive:
$0.65*3=$1.95
$5-$1.95=$3.05
According to this, the answer is that Arianna should receive $3.05 in change.
can someone explain how to find the slope
Answer:
slope is rise over run. first select a point. I'll use (0,-1). to get to the next complete point, you would have to go up (rise) 3 points and right (run) 1 point. the rise over run (3/1) divides evenly to 3. hope this helps!
