Answer:
Option C
Step-by-step explanation:
Domain is the set of x-values of the function.
Similarly, Range of a function is defined by the set of y-values of the function.
For the given set of domain → {0, 3, 7}
Range of function → f(x) = 2ˣ + 4
x 0 3 7
f(x) 2⁰+ 4 = 5 2³+ 4 = 12 2⁷ + 4 = 132
Therefore, range of the given function will be → {5, 12, 132}
Option C will be the answer.
What is 9 x 2/3 as a fraction.
The expression 9x2/3 can be written in fraction form as, 18/3
What is a fraction?Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.
Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.
9 times 2/3 can be calculated by first converting 9 to a fraction and then multiplying that fraction by 2/3. To convert 9 to a fraction, we write it over 9/1 x 2/3
Next, we multiply the two fractions by multiplying the numerators (the top numbers) together and the denominators (the bottom numbers) together:
⇒ (9/1) x (2/3)
⇒ (9 x 2) / (1 x 3)
⇒ 18/3
So, 9 times 2/3 as a fraction is 18/3.

May someone help me with this. I have to use the Pythagorean theorem for this problem. May you show steps too?
Answer:
the missing side value is 6.7.
Step-by-step explanation:
so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.

*also pls look at both images :)*
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63

The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
cm
Submit Answer
attempt 1 out of 2
Answer:
18.9 cm
Step-by-step explanation:
Pythagorean Theorem --> A² + B² = C²
2² + B² = 19²
4 + B² = 361
B² = 357
√357 --> 18.89 --> 18.9
The measure of the other leg to the nearest tenth will be 18.9 centimeters.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Let the other leg be 'x'. Then the measure of the other leg will be given as,
19² = x² + 2²
361 = x² + 4
x² = 361 - 4
x² = 357
Take square root on both sides, then we have
x = √357
x = 18.8944
x ≈ 18.9 cm
The measure of the other leg to the nearest tenth will be 18.9 centimeters.

This is the third time that I am asking the same question!
Answer:
Step-by-step explanation:
10)
P10 = (2,7)
and parallel to y -4x = 5
y = 4x + 5
so any thing with a slope of 4 but going thur P1
y-7 = 4(x-2)
y-7 = 4x -8
10) y = 4x -1
11)
P11 = (5,-1)
and parallel to
y = -1/2x + 2
anything with a slope of -1/2 but going thur P2
y- (-1) = -1/2(x-5)
y + 1 = -1/2x +5
11) y = -1/2x + 4
12)
P12 = ( 3, 0 )
-2y + 3x = 0
perpendicular to, so the slope is reciprocal and opposite sign
3x = 2y
3/2x = y
y = 3/2x
-2/3 is the perpendicular slope
y-0 = -2/3(x-3)
12) y = -2/3x + 2
13)
P13= ( 6, 3)
3x- y = 6
perpendicular to, so the slope is reciprocal and opposite sign
3x-6 = y
y = 3x -6
-1/3
y-3 = -1/3(x-6)
y-3 = -1/3x + 2
13) y = -1/3x + 5

Answer:
14 on the bottom and 6 going up and down and then you complete the triangle make the other up and down side 6 so it makes a triangle not a sideway one
There are 11 possible values of side x, which are 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
The side lengths of the triangle,
a = 6 inches and b = 14 inches.
A triangle is formed when the length of third side is greater than difference of two sides and less than sum of two sides.
Let the third side is x,
So, the possible values of x could be,
14 - 6 < x < 14 + 6
8 < x < 20

Piere is an electrician
He uses this formula to work out the amount ,$c , to charge for a job that takes ×hours
C=20+30×
He starts a job at 9 30 and finishes at 1 pm
Work out his charge for this job
Pls show me formula
Answer:
c=$125
Step-by-step explanation:
9:30--12:30 is three hours, then another half hour till 1pm total hours is 3.5
c = 20+30*3.5
c=20 + 105
c = 125
The charge for Piere's work is $125 by using the formula C = 20+30x.
What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
Let the amount in dollar,$ be C.
Let the hours be x.
The equation is C = 20+30x.
He starts a job at 9:30 and finishes at 1 pm. So, the time x is 3.5 hours.
⇒ [tex]1pm-9:30 am=3.5 hours[/tex]
Thus charge for the electrician is
⇒ [tex]C=20+30(3.5)[/tex]
⇒ [tex]C=125[/tex]
Hence we can conclude that the charge for Piere's work is $125 by using the formula C = 20+30x.
