Which is the range of the relation y = 2x2 + 3x if the domain is the set {-2, -1, 0}?
A {10,1,0)
B.{-1,-5,0)
c. {2,-1,0)
D. (2. 1.0)
Given:
The function is:
[tex]y=2x^2+3x[/tex]
Domain is the set {-2, -1, 0).
To find:
The range of the given relation.
Solution:
We have,
[tex]y=2x^2+3x[/tex]
Substituting [tex]x=-2[/tex], we get
[tex]y=2(-2)^2+3(-2)[/tex]
[tex]y=2(4)+(-6)[/tex]
[tex]y=8-6[/tex]
[tex]y=2[/tex]
Substituting [tex]x=-1[/tex], we get
[tex]y=2(-1)^2+3(-1)[/tex]
[tex]y=2(1)+(-3)[/tex]
[tex]y=2-3[/tex]
[tex]y=-1[/tex]
Substituting [tex]x=0[/tex], we get
[tex]y=2(0)^2+3(0)[/tex]
[tex]y=0+0[/tex]
[tex]y=0[/tex]
The range for the given relation is {2, -1,0}. Therefore, the correct option is (c).
If f(x)=7(x-1)+8f(x)=7(x−1)+8 , what is the value of f(1)f(1) ?
Answer:
8
Step-by-step explanation:
All you have to do is plug in 1 for the x value, which leaves you with the equation 7(1-1) + 8, then you simplify it to be 7(0) + 8
7 times 0 is 0, so you are left with 8 as your answer

Find the RATIO and the EXACT VALUE of the given Sec B.
Answer:
13/5
Step-by-step explanation:
Cos is the opposite of Sec si first find the Cos of B which is 5/13, which would mean the Sec B would 13/5.
Answer:
Step-by-step explanation:
Recall that the secant function is the reciprocal of the cosine function. The cosine function is defined as
adj side
cos Ф = ------------------
hypotenuse
and so the secant function is
hypotenuse 13
sec Ф = ------------------ which here is --------- = sec B
adj side 5
which does not describe the equation
[tex] \sqrt{x = - 2} [/tex]
Answer:
which of what ?
and the equation is not right. I don't know what you mean.
do you mean x = sqrt(-2) ?
all I can tell you just based on that assumption is that you can transform that into
[tex]x = \sqrt{2} \times i[/tex]
you know,
[tex]i = \sqrt{ - 1} [/tex]
but what else you might need is completely unclear.

Given:
The figure of a rhombus QRST.
To find:
A. The value of x.
B. The measure of angle RQP.
Solution:
A. We need to find the value of x.
We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.
[tex]m\angle RPS=90^\circ[/tex] [Right angle]
[tex](5x+15)^\circ=90^\circ[/tex]
[tex](5x+15)=90[/tex]
[tex]5x=90-15[/tex]
[tex]5x=75[/tex]
Divide both sides by 5.
[tex]x=\dfrac{75}{5}[/tex]
[tex]x=15[/tex]
Therefore, the value of x is 15.
B. We need to find the measure of angle RQP.
From the given figure, it is clear that
[tex]m\angle RQP=(2x+3)^\circ[/tex]
Putting [tex]x=15[/tex], we get
[tex]m\angle RQP=(2(15)+3)^\circ[/tex]
[tex]m\angle RQP=(30+3)^\circ[/tex]
[tex]m\angle RQP=33^\circ[/tex]
Therefore, the measure of angle RQP is 33 degrees.

Find the slope-intercept equation of the line that passes through (2,-5) and has a slope of 1/3
Answer:
y = 1/3x - 17/3
Step-by-step explanation:
Given:
Passes through (2, -5)
m = 1/3
Slope-intercept:
y - y1 = m(x - x1)
y - (-5) = 1/3(x - 2)
y + 5 = 1/3x - 2/3

Since these are right triangles, we can use Pythagorean Theorem.
Pythagorean Theorem: a^2 + b^2 = c^2
50^2 + 20^2 = c^2
2500 + 400 = c^2
2900 = c^2
c = sqrt[ 100 * 29]
c = 10 sqrt[29]
In the boxes, a = 10, b = 29.

Find the height of the cylinder given the surface area and one
other dimension:r = 5 in SA
659,4 in?
Answer:
C 16 inches
Step-by-step explanation:
a cylinder is 2 circles (1 on top, 1 at the bottom) and a round "mantle" connecting the two circles.
so, the surface area is the sum of the areas of both circles and the "mantle".
this "mantle" can be cut open and cut off the circles, and then be placed flat on the table. then it is simply a rectangle with the side lengths cylinder height (h) and circle circumference.
circle area : pi × r²
circle circumference : 2 × pi × r
rectangle area :
length × width = circle circumference × h
SA = 659.4 inches² = 2×(pi × r²) + (2×pi×r)×h =
= 2×pi×25 + 2×pi×5×h = 50×pi + 10×pi×h
=> 659.4 - 50×pi = 10×pi×h
=> (659.4 - 50×pi) / (10×pi) = h = 16 inches

Write each quadratic expression in standard form. Draw a diagram if needed.
(x+4)(x-1)
Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0
The graph of the equation created with MS Excel is attached

A survey of teens suggested that 33% can name at least one professional baseball player, and 90% of those teens can also name at least one professional football player. In the entire population, 64% can name at least one professional football player. What percentage of teens can name at least one player from these sports? (0.33)(0.64) = 0.2112 0.33 + 0.64 = 0.97 0.33 + 0.64 – (0.33)(0.64) = 0.7588 0.33 + 0.64 – (0.90)(0.33) = 0.673
Answer:
[tex]d.\ 0.33 + 0.64 – (0.90)(0.33) = 0.673[/tex]
Step-by-step explanation:
Given

Aubrey came across an ad for a brand new gym that does not charge a sign-up fee but charges a membership fee of $52.00 per month. She is trying to decide which gym would be the best option if she's only planning on joining for 6 months. A. What would be the total cost for 6 months of membership at her local gym? (Charges $18.00 per month plus a sign-up fee of $95.00 ; Use the expression 18m+95 to find your answer.) B. What would be the total cost for 6 months of membership at the brand new gym? (Charges $52.00 per month and no sign-up fee. Use the expression 52m to find your answer.) C. Which gym would be the better deal for a 6 month membership? (Write either: Local Gym OR New Gym )
Answer:
LOCAL GYM
Step-by-step explanation:
Local gym :
Signup fee = $95 ; monthly cost = $18
6 months cost :
18m + 95
18(6) + 95 = $203
6 months cost at new gym :
$52 per month
Cost = $52 * 6 = $312
The best gym for a 6 month deal is the local gym
Local gym Cost < new gym cost

Answer:
14.55'
Step-by-step explanation:
Cosine rule
c^2 = a^2 + b^2 - 2ab cos(C)
here
a=11
b=23
C = 150°
Substitute in cosine rule,
c^2 = 11^2 + 23^2 - 2(11)(23) cos (150°)
= 121 + 529 -2 (11) (23) sqrt(3)/2
=211.791
c = sqrt(211.791)
= 14.55
Write an equation of the line that passes through (0,9) and is parallel to the line y = 8x+7.
Answer:
[tex]y=8x+9[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slopes and different y-intercepts1) Determine the slope
[tex]y = 8x+7[/tex]
From the given equation, we can identify 8 to be in the place of m, making 8 the slope. Because parallel lines always have the same slopes, the line we're currently solving for will also have a slope of 8. Plug this into [tex]y=mx+b[/tex]:
[tex]y=8x+b[/tex]
2) Determine the y-intercept
[tex]y=8x+b[/tex]
The y-intercept occurs when x=0. The given point is (0,9), telling us the the y-intercept is 9. Plug this into [tex]y=8x+b[/tex]:
[tex]y=8x+9[/tex]
I hope this helps!
