Answer:
Range: {1, 3, 11}
Step-by-step explanation:
To find the range, just substitute the inputs into the function to find the outputs.
f(-2) = 2(-2) + 5
f(-2) = -4 + 5
f(-2) = 1
f(-1) = 2(-1) + 5
f(-1) = -2 + 5
f(-1) = 3
f(3) = 2(3) + 5
f(3) = 6 + 5
f(3) = 11
So the range is: {1, 3, 11}.
The number of cars sold per month can be modeled by f(x) = 0.04x^3 + 0.2x^2 + 0.5x + 60, where x represents the number of months since March. Let g(x) = f(x) + 30. Which of the following gives the rule for g and the correct explanation of the meaning if the transformation in terms of monthly car sales?
Answer:
0.04x^3+0.2x^2+0.5x+90 vertical shift 30 units up, increase of 30 units per month

Answer: 69.12
Step-by-step explanation: circumference=2*pi*radius
Answer:
The circumference of the circle is 69.12 m
Step-by-step explanation:
Circumference of a Circle
Given a circle of radius r, the circumference or perimeter of the circle is calculated by the formula:
[tex]C=2\pi\ r[/tex]
The circle shown in the image has a radius of r=11 m, thus the circumference is:
[tex]C=2\pi\ *11[/tex]
[tex]C=22\pi[/tex]
Calculating:
C = 69.12 m

Sissy wants to enlarge a picture of a constellation so that she can put it on the wall in her daughter’s room. What will be the area of the enlarged picture on the wall?
24 in.2
108 in.2
224 in.2
486 in.2
Answer: 486 in
Just did this on edge
The enlargement transformation applied to the rectangular figure gives
a rectangle that is enlarged and similar to the figure.
Correct response:
The area of the enlarged picture is 486 in.²The given dimensions of the picture are;
Height, [tex]\overline{MN}[/tex] = 6 in.
Width, [tex]\overline{LP}[/tex] = 4 in.
The length of QL' = 12 + 42 = 54
By similar triangles, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]
Which gives;
[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]
[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]
Given that an enlargement gives similar figures, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]
Therefore;
[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]
Which gives;
[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]
The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]
Which gives;
A = 27 × 18 = 486
The area of the enlarged picture on the wall is A = 486 in.²

x+3y=0 and 12y=-4 equation plz help.
Answer:
[tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]
Step-by-step explanation:
So we can equate the second equation in terms of y by dividing both sides by 12:
[tex]y = -\frac{1}{3}[/tex]
Let us substitute this into the first equation:
[tex]x + 3y = 0[/tex]
then becomes
[tex]x + 3(-\frac{1}{3} ) = 0[/tex]
which simplifies to
[tex]x - 1 = 0[/tex]
Finally solving for x gives us:
[tex]x = 1[/tex]
Therefore, [tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]

24. Sam, Sonny and Sal are camping in their tents. If the distance between Sam and
Sonny is 153ft, the distance Sam and Sal is 201ft, and the distance between Sonny
and Sal is 175ft, what is the angle of Sonny's line of sight to both Sam and Sal to the
nearest whole degree?
a. 25°
b. 75°
c. 57°
d. 123°
Answer:
Step-by-step explanation:
Answer:
b. 75°
Step-by-step explanation:
Draw a triangle. Write a person name and a point name (a letter) at each vertex: Sam A, Sonny B, and Sal C at the vertices.
Write the distances as AB = c = 153 ft; AC = b = 201 ft; BC = a = 175 ft.
We are looking for angle B.
Since we have a triangle with three side lengths and no angle measures, we use the Law of Cosines.
[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]
[tex] 201^2 = 175^2 + 153^2 - 2(175)(153) \cos B [/tex]
[tex] 40401 = 30635 + 23409 - 53550 \cos B [/tex]
[tex] -53550 \cos B = -13643 [/tex]
[tex] \cos B = \dfrac{-13643}{-53550} [/tex]
[tex] \cos B = 0.254771242 [/tex]
[tex] B = \cos^{-1} 0.254771242 [/tex]
[tex] B = 75^\circ [/tex]

What is the value of y?
Find the values of x, y, and z.
Answer:
y=25.5°
Step-by-step explanation:
because there's an isosceles triangle, 180-51 = 129
so 129/2 = 64.5, which is X
there is also a right angle so 90-64.5 = 25.5, which is y
