Answer:
2x^2 +11
Step-by-step explanation:
2x^2 +11
Step-by-step explanation:
(x) = 3 x^2 + 2
g(x) = x^2 - 9
(f - g)(x) =3 x^2 + 2 - (x^2 - 9)
Distribute the minus sign
= 3x^2 +2 - x^2 +9
Combine like terms

A pizza is cut into pieces. Kevin takes 1/4 of the total pieces. Keith takes one piece less than twice the number of pieces Kevin took. How many of pizza are left ?
a. 1/4x
b. 1/4x+1
c. 1/2x+1
d. 3/4x-1
Answer: I believe the answer is d or b
Step-by-step explanation:
The number of pizza pieces left is (x + 4) / 4. Option c
How to determine the number of pizza pieces leftLet's assume the total number of pizza pieces is represented by 'x'.
Kevin takes 1/4 of the total pieces, which is (1/4) * x = x/4.
Keith takes one piece less than twice the number of pieces Kevin took, which is 2 * (x/4) - 1 = (2x/4) - 1 = x/2 - 1.
To calculate the number of pizza pieces left, we need to subtract the sum of Kevin's and Keith's pieces from the total number of pieces (x):
Leftover pieces = Total pieces - (Kevin's pieces + Keith's pieces)
= x - (x/4 + x/2 - 1)
= x - (3x/4 - 1)
= x - 3x/4 + 1
= (4x - 3x + 4) / 4
= (x + 4) / 4
Therefore, the number of pizza pieces left is (x + 4) / 4.
The correct option among the given choices would be (c) 1/2x + 1.

Find the value of k if the remainder is 13 when
25 + 4x4 + kx3 + x – 11 is divided by x + 3
Answer:
[tex]k = \frac{322}{27} [/tex]
Step-by-step explanation:
x + 3 = 0 → x = - 3
25 + 4(-3)⁴ + k(-3)³ + (-3) - 11 = 13
25 + 324 - 27k - 3 - 11 = 13
349 - 27k - 14 = 13
349 - 14 - 13 = 27k
349 - 27 = 27k
322 = 27k
k = 322/27

* 4. A circle is divided into ten equal sectors.
a. Find the measure of each central angle.
b. If the diameter is 50 in., find the length of an arc of one of the
sectors.
HELP PLEASE
Answer:
a. Find the measure of each central angle.
The central angle of a circle = 360 °
Now Pie is cut into 10 equal sectors
Angle of each sector is given by
Angle of sector = Total central angle/number of sectors
[tex] = {360}^{0} \div 10[/tex]
[tex] = {36}^{0} [/tex]
Hence , the central angle of one slice of pie is 36°
b. If the diameter is 50 in., find the length of an arc of one of the sectors.
length of an arc of one of the sectors =
[tex] = \frac{1}{n} \times 2\pi \times r[/tex]
[tex]= \frac{1}{10} \times 2\ \frac{22}{7} \times 50[/tex]
[tex] = 31.42 \: in[/tex]
Answer: 36 degrees
Step-by-step explanation:
A circle is 360 degrees.
If you divide 360 degrees by 10, (10 sectors) you get 36.
The answer is therefore 36 degrees. (don't forget your labels!!!)

Find the ‘exact’ perimeter of each triangle
Answer:
[tex]\huge\boxed{\sf 8 + 4\sqrt{2} \ cm }[/tex]
Step-by-step explanation:
[tex]\theta = 45 \textdegree[/tex]
opposite = 4 cm
Using tan first to find the adjacent side:
[tex]\displaystyle tan \theta = \frac{opposite}{adjacent} \\\\tan \ 45 = \frac{4}{adjacent}\\\\1 = \frac{4}{adjacent} \\\\Multiply \ 'adjacent' \ to \ both \ sides\\\\adjacent = 4 \ cm[/tex]
Finding Hypotenuse now by using Pythagorean theorem:
[tex](Hyp)^2 = (base)^2 + (perp)^2[/tex]
where base = 4, hyp = 4
(Hyp)² = (4)² + (4)²
(Hyp)² = 16 + 16
(Hyp)² = 32
Take sqrt on both sides
[tex]Hyp = 4\sqrt{2}[/tex] cm
Exact perimeter of triangle:

Choose the kinds of symmetry the following figure has: point, line, plane, or none.
none
plane
point
line
Explanation:
Can we rotate the figure some angle smaller than 360 degrees and have it match up with its original image? The answer to that is "no". Any such rotation will change the image to something else. Therefore, this figure does not have any point symmetry (aka rotational symmetry).
Can we reflect one half of the figure over some line to get the other half? The answer here is also "no". The diagram has no reflectional symmetry either.
Plane symmetry is ruled out because that only applies to 3D settings.

The value of x when y is 8 is 9.75.
It is given that
y ∝ 1/x
y = k/x......(1)
Where k is a constant of proportionality
What is the constant of proportionality?The constant of proportionality is the ratio that relates two given values.
When y =13, x=6
Means, 13 = k/6
k = 78
Putting the value of k in equation (1)
y = 78/ x
8 = 78/ x
x =9.75
Therefore, The value of x when y is 8 is 9.75.
