Step-by-step explanation:
f(x)=4(x-2)^2 + 3 parentaties first
f(x) = 4 (x^2 - 4)+ 3 multiply by what's infront parentaties
f(x) = 4x^2 - 16 + 3 combine light terms

Answer:
44 minutes
Step-by-step explanation:
Given that :
Start time = 1:37 pm
End time = 2:21 pm
The time difference is obtained by subtracting the start time from the end time :
. End time - start time
2:21 pm - 1:37 pm
From 1:37 pm to 2 pm = 23 minutes
From 2 pm to 2:21 pm = 21 minutes
Total minutes = (23 + 21) minutes = 44 minutes

A. (0, 5)
B. (6, 10)
C. (10, −10)
D. (3, −3)
Answers
Answer: C. (10, -10)
Step-by-step explanation:
Given
1) 2x-3y=50
2) 7x+8y=-10
Multiply both sides of 1) equation by 3.5
1) 3.5(2x-3y)=3.5×50
7x-10.5y=175
2) 7x+8y=-10
Subtract 2) equation from the 1)
(7x-10.5y)-(7x+8y)=175-(-10)
-18.5y=185
y=-10
x=10
(10, -10)

Hollis put a layer of boxes in the bottom of a container. Each box has a volume of 1 cubic foot. The base layer of boxes in the container in shown. Hollis will need 8 of these layers to completely fill the container. What is the volume of the container in cubic feet?
Answers
Answer:
288 ft³
Step-by-step explanation:
Given that
The volume of each box is 1 cubic foot
And, Hollies required 8 of these layers
Now based on the above information
We assume that the dimension of the base layer is 6 by 6
So, the volume of the container is
= Length × Width × Height
where,
Length = 6 ft
Width = 6 ft
And, Height = 8 ft
So,
= 6 ft × 6 ft × 8 ft
= 288 ft³

ABC is a straight line. Work out the size of the angle marked x
Answers
Answer:
x = 57°
Step-by-step explanation:
angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.
110-53= 57. therefore, x = 57°.
The measure of angle x in the straight line ABC is 57 degrees
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
x + 53 + 70 = 180° (sum of angles in a straight line).
Hence:
x = 57°
The measure of angle x in the straight line ABC is 57 degrees

Now, suppose assuming the true fraction of voters is .65, the estimated standard deviation of X is given as 6.65. Suppose you find that 115 people actually voted yes in the random sample of 200. Conduct hypothesis testing using p value approach at 5% significance level to determine the validity of Candidate A’s claim that he was at least supported by 65% of the voters. (Make sure you show the steps of hypothesis testing)
Answers
Answer:
reject H0 ; conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters
Step-by-step explanation:
x = 115
n = 200
Phat = x / n = 115 / 200 = 0.575
H0 : P0 ≥ 0.65
H1 : P0 < 0.65
TEST STATISTIC :
Phat - P0 ÷ sqrt[(P0(1-P0))/n]
0.575 - 0.65 ÷ sqrt[(0.65(0.35))/200]
-0.075 ÷ 0.0337268
Test statistic -2.237
Pvalue :
P(Z < - 2.237) = 0.012643
α = 0.05
Pvalue < α
0.012643 < 0.05 ; We reject H0
We can conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

7) ARC DE = 189
ARC EF = 13

8) ARC MN= 65
ARC NP= 115
ARC NQP= 245
Explanation:
7) 2 *vertical angles so double* (x-3) + 2 * vertical angles so double* 12x-25) = 360 *Total Degree of a circle*
2x-6 +24x-50 =360
26x -56 = 360
26x=416
x=16
Plug it back into the Formula.
Arc EF = x-3
16-3 = 13
Arc 12x -25 *Vertical Angels so same formula as Arc GF*
12(16)-3= 189
ARC DFG = 360 - ARC DG
360 - 13 = 347
8) 10x -45 = 6x-1 *vertical angles equal each other*
4x-45 =-1
4x =44
x=11
ARC MN = 10x -45
10(11)-45=65
ARC NP = 0.5(360 - 2(ARC MN))
0.5(360-130) = 115
ARC NQP = 360 -NP

A candy company can sell fruit gums in rectangular boxes or in cylindrical tubes. Each box is 8 cm by 3 cm by 7 cm. Each cylinder has radius 3 cm and height 6 cm. The company wants the packaging that uses less material. Which packaging should the company choose? Justify your choice.
Answers
Answer:
i. The company should use the cylindrical tubes.
ii. This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
Step-by-step explanation:
i, Which packaging should the company choose?
The packaging that uses less material is the one with the least surface area. So, we find the surface area of each material.
For the rectangular box, the surface area, A = 2(lb + lh + bh) where l = length, b = breadth and h = height. Since each box is 8 cm by 3 cm by 7 cm,l = 8 cm, b = 3cm and h = 7cm.
So, ,A = 2(lb + lh + bh)
,A = 2( 8 cm × 3 cm + 8 cm × 7 cm + 3 cm × 7cm)
A = 2(24cm + 56 cm + 21cm)
A = 2(101 cm²)
A = 202 cm²
For the cylindrical tube, the surface area, A' = 2πr(r + h) where r = radius of cylinder and h = height of cylinder.
Since each cylinder has radius 3 cm and height 6 cm, r = 3cm and h = 6 cm.
So, A' = 2πr(r + h)
A' = 2π(3 cm)(3 cm + 6cm)
A' = (6π cm)(9 cm)
A' = 54π cm²
A' = 169.65 cm²
Since the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
The company should use the cylindrical tubes.
ii. Justify your choice.
This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
