Which do not have set of real numbers as its domain
If a function has no root and no denominator, then the domain of such function is a set of all real numbers
The given functions (a) to (d) do not have square roots and do not have denominators.
Hence, all functions have the set of real numbers as their domain

Answer:
6 m
Step-by-step explanation:
By Pythagoras Theorem:
[tex]x = \sqrt{ {10}^{2} - {8}^{2} } \\ \\ x = \sqrt{100 - 64} \\ \\ x = \sqrt{36} \\ \\ x = 6 \: m[/tex]
Step-by-step explanation:
10² = 8² + x²
x² = 10² - 8²
x² = 36
x = √36
x = 6
Which statement accurately describes the graph 2y=4x+8?
IM IN A TEST HURRY PLEASE!!
The statement which describes the given line the best is required.
The correct statement is an increasing line that passes through [tex](0,4)[/tex]
Equation of linesThe given equation is [tex]2y=4x+8[/tex]
Two points of the line are
[tex]x=0[/tex]
[tex]2y=0+8\\\Rightarrow y=4[/tex]
[tex](0,4)[/tex]
[tex]y=0[/tex]
[tex]0=4x+8\\\Rightarrow x=-2[/tex]
[tex](-2,0)[/tex]
The line passes through points [tex](0,4),(-2,0)[/tex]
The slope intercept form of the line is
[tex]y=\dfrac{4x+8}{2}\\\Rightarrow y=2x+4[/tex]
The slope is [tex]2[/tex]
Since, the slope is positive the line is increasing.

Answer:
1st one is correct ....................
Answer:
x = 8, y = 12
Step-by-step explanation:
Since the triangles are congruent, we know that the parallel sides are equal to each other.
So,
4x - 7 = 3x + 1
4x - 3x = 1 + 7
x = 8
x + y = 20
8 + y =20
y = 20 - 8
y = 12
`what is the sooulition to x + 8 = 25
Answer:
17
Step-by-step explanation:
Well you have to get x by itself so....
subtract 8 from both sides
25 -8 = 17 there is your answer
Hey there!
x + 8 = 25
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 25 - 8
SIMPLIFY IT!
x = 25 - 8
x = 17
Therefore, the answer should be: x = 17
Good luck on your assignment & enjoy your day!

Vanessa throws a tennis ball in the air. The function h(t) = -15t2 + 45t + 10 represents the distance in feet, that the ball is from the ground at any time in seconds, t. What is the maximum height of the ball?
Answer:
43.75feet
Step-by-step explanation:
Given the height of the tennis ball expressed as;
h(t) = -15t^2 + 45t + 10
At maximum height, the velocity of the ball is zero
v = dh/dt
dh/dt = -30t + 45
Since dh/dt = 0, hence;
0 = -30t + 45
30t = 45
t = 45/30
t = 3/2
t = 1.5secs
Substitute t = 1.5 into the expression given
h(1.5) = -15(1.5)^2 + 45(1.5) + 10
h(1.5) = -15(2.25)+67.5+10
h(1.5) = -33.75+77.5
h(1.5) = 43.75feet
Hence the maximum height of the ball is 43.75feet

Work out m and c for the line: y+2x=3
Answer:
m = - 2, c = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y + 2x = 3 ( subtract 2x from both sides )
y = - 2x + 3 ← in slope- intercept form
with m = - 2 and c = 3

There are 12 boys and 13 girls in a class. If the teacher randomly chooses a student's name out of a hat, what is the probability it will be a girl?
◯ 48%
◯ 50%
◯ 52%
◯ 92%
The probability of selecting a girl is 52%
How to determine the probability?The given parameters are:
Boy = 12
Girl =13
The probability of selecting a girl is:
P(Girl) = Girl/Total
This gives
P(Girl) = 13/(12 + 13)
Evaluate
P(Girl) = 52%
Hence, the probability it will be a girl is 52%

A store purchased jeans for $15 a pair. The store increased the price of the jeans by 65%. One month later, the jeans were on sale for 15 - off the store price. How much would a customer pay for the jeans on sale? Please help
Answer:
$21.04
Step-by-step explanation:
Steps to take to derive the answer
Determine the price after the price increase of 65%Determine the price after the 15% offPrice after increase increase (100% + increase in price) x purchase price of the jeans
(100% + 65%) x 15
165% x 15
1.65 x $15 = $24.75
Price after the decrease in price = (100% - percentage decrease in price) x price after the 65% increase in price
(100% - 15%) x $24.75
85% x $24.75
0.85 x $24.75 = $21.04
