1.) Factor the expression by grouping:
- First, the expression needs to be rewritten as [tex]x^2+ax+bx-48[/tex]. To find a and b, set up a system to be solved:
[tex]a+b=13[/tex][tex]ab=1(-48)=-48[/tex]2.) List all such integer pairs that give product −48:[tex]-1,48[/tex][tex]-2,24[/tex][tex]-3,16[/tex][tex]-4,12[/tex][tex]-6,8[/tex]3.) Calculate the sum for each pair:[tex]-1+48=47[/tex][tex]-2+24=22[/tex][tex]-3+16=13[/tex][tex]-4+12=8[/tex][tex]-6+8=2[/tex]4.) The solution is the pair that gives sum 13:[tex]a=-3[/tex][tex]b=16[/tex]5.) Rewrite [tex]\bold{x^2+13x-48}[/tex]:[tex]x^2+13x-48=(x^2-3x)+(16x-48)[/tex]6.) Factor out [tex]\bold{(x)}[/tex] in the first and 16 in the second group:[tex]x(x-3)+16(x-3)[/tex]7.) Factor out common term [tex]\bold{x-3}[/tex] by using distributive property:[tex](x-3)(x+16)[/tex]
So your answer is [tex]\bold{(x-3)(x+16)}[/tex] or [tex]\bold{(x+16)(x-3)}[/tex].

What is the measure of _Y, in degrees?
y
A. 116°
B. 32°
C. 640
D. Cannot be determined
Answers
Answer:
C. 116º
Step-by-step explanation:
Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.
32 + 32 = 64
180 - 64 = 116
which of the following statements is false about the area of a circle
Answers
Answer:
Step-by-step explanation:
All are true except for the second. Only the second is false.
(pi)(d) is the circumference (not the area) of a circle.
The incorrect statement is [tex]A = \pi d[/tex].
The correct option is 2.
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well. The region that includes the base(s) and the curved portion is referred to as the total surface area. It is the overall area that the object's surface occupies. The total area of a form with a curved base and surface is equal to the sum of the two areas.
As per the given data:
We have to find out the incorrect statements out of the given options about the area of a circle.
[tex]A = \pi r^2[/tex]
This statement is correct, as the area of a circle is pi times square of the radius.
[tex]A = \pi d[/tex]
This statement is incorrect, as the area of a circle is given by:
[tex]A = \pi r^2 =\frac{ \pi d^2}{4}[/tex]
The area of a circle determines how much space is covered by the circle.
This statement is correct.
The area of a circle describes the number of square units that fit inside the circle.
This statement is correct.
Hence, the incorrect statement is [tex]A = \pi d[/tex].

Answer:

Step-by-step explanation:
54-7=47
I'm assuming we are trying to find Rita's score. We know that the total is 54. "The sum" refers to addition, so we must reverse the problem to find her score
54- 7= 47

Drag the symbol to complete the solution to this inequalities
Answers
Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.
The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is ≤.
To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]
Rearrange the inequality as follows:
[tex]\frac{x}{2.2} \le 6[/tex]
The solution to the inequality is:
[tex]x \leq 13.2[/tex]
Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.
Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

What is the measure of angle N?
Answers
=========================================================
Work Shown:
Apply the law of sines
sin(N)/MO = sin(O)/MN
sin(N)/18 = sin(17)/6
sin(N) = 18*sin(17)/6
sin(N) = 0.87711511416821 ................. which is approximate
N = arcsin(0.87711511416821)
N = 61.296295678111
N = 61 degrees approximately
----------------------
Notes:
Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.Let f be the function defined by f(x)=x^3+x^2+x. Let g(x)=f^-1(x), where g(3)=1. What is the value of g'(3)?
Answers
Answer:
1/6
Step-by-step explanation:
Given the function
f(x)=x^3+x^2+x
Get the inverse. Let y = f(x)
y = x^3+x^2+x
Replace y with x
x = y³+y²+y
Differentiate with respect to x
1 =3y²dy/dx + 2ydy/dx + dy/dx
1 = (3y²+2y+1)dy/dx
dy/dx = 1/3y²+2y+1
g'(x) = 1/3(g(x))²+2g(x)+1
If x = 3
g'(3) = 1/3(g(3))²+2g(3)+1
g'(3) =1/3(1)²+2(1)+1
g'(3) = 1/3+2+1
g'(3) = 1/6
Hence g'(3) = 1/6
