Answer:
y=-7
Step-by-step explanation:
if g(x) is g(-2) that means that x=-2 so we plug that in so 5*-2+3
5*-2+ -10

Which statements are true about the polynomial function?

Select each correct answer.
f(x)=0 when x=−1 .
f(−1)=0
(x−1) is a factor of f(x) .
f(x) divided by (x−1) has a remainder of 0.
Answers
Answer:
D. f(x) divided by (x−1) has a remainder of 0.
C. (x−1) is a factor of f(x) .
Step-by-step explanation:
Just took a test with this question these are the answers!
The statements that are true about the polynomial function are;
(x−1) is a factor of f(x). f(x) divided by (x−1) has a remainder of 0.Given the polynomial function [tex]f(x)=x^3-x^2-4x+4[/tex]
If x = -1, hence;
[tex]f(-1)=(-1)^3-(-1)^2-4(-1)+4\\f(-1)=-1-1+4+4\\f(-1)=-2+8\\f(-1) =6[/tex]
This shows that f(x) ≠ 0 when x = −1 .
To check if x - 1 is a factor, we will substitute x = 1 into the function and check if the result is zero as shown:
[tex]f(1)=1^3-1^2-4(1)+4\\f(1)=1-1-4+4\\f(1) =0[/tex]
This shows that (x−1) is a factor of f(x).This also shows that if f(x) divided by (x−1) has a remainder of 0.

State what additional information is required in order to know that the triangles are congruent
for the reason given.
Only for 5 and 6
Answers
Answer:
Step-by-step explanation:
5). Reason for the congruence is given as SSS.
"Property SSS for the congruence of two triangles states that all three sides of the triangles must be congruent."
In the given triangles ΔMLN and ΔULN,
ML ≅ LU [given]
NL ≅ NL [Reflexive property]
To fulfill SSS property third sides of the given triangles should be given as congruent.
Therefore, additional information required will be MN ≅ NU
6). SAS property of congruence states that "two sides and included angle between these sides of two triangles must be congruent"
From the given triangles ΔPWS and ΔVXW,
PW ≅ VW [Given]
∠PWS ≅ ∠XWV [Vertically opposite angles]
Therefore, to fulfill the property of SAS additional information required will be,
SW ≅ WV

A football coach needs to divide 48 players into two groups. He wants the ratio of the players in group 1 to players in group 2 to be 3. How many players in group 2?
Answers
Answer:
45
Step-by-step explanation:
A ratio shows us the number of times a number contains another number. The number of players in group 2 is 12.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the coach wants the ratio of the players in group 1 to players in group 2 to be 3. Therefore, the ratio can be written as,
Number of players in group1/Number of players in group2 = 3/1
Multiply the numerator and the denominator of the ratio by x,
Number of players in group1/Number of players in group2 = 3x /1x
Now, the total number of players can be written as,
3x + x = 48
4x = 48
x = 48/4
x = 12
Further, the number of players in group 2 can be written as,
Number of players in group2 = x = 12
Hence, the number of players in group 2 is 12.

On a scale drawing of the front of a square earring, each side of the earring is 3.2cm. The scale from the earring to the drawing is 4mm to 2cm. What is the area of the front of the actual earring?
Answers
40.96 mm
3.2(10) = 32; 3.2 cm → 32 mm
each side of scale drawing is 32 mm
2(10) = 20; 2 cm → 20 mm
scale is 4 mm to 20 mm
[tex]\frac{4}{20}= \frac{x}{32}[/tex]
cross-multiply:
32(4) = 128
128 / 20 = 6.4
each side of the actual drawing is 6.4 mm.
6.4 * 6.4 = 40.96
40.96 mm
40.96 mm
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that the scaling of drawing is 4mm to 2cm of actual drawing and the scaled drawing side of square earring is 3.2cm.
Now, corelating the scale given which means for 1mm of actual side of earring the drawing scale is 0.5 cm or 5mm. Therefore, for having 3.2 cm of side of earring in drawing let [tex]x[/tex] be the actual side this is calculated below :
[tex]\begin{aligned}20 \text{mm}&\rightarrow 4\text{mm}\\32\text{mm}&\rightarrow x\text{\:mm}\\\frac{4}{20}&=\frac{x}{32}\\x&=6.4 \text{mm}\end{aligned}[/tex]
Now, the actual side of earring is 6.4 mm therefore, the area of the front of earring will be : 6.4 mm x 6.4 mm =40.96 mm
