The integral can be written as:
∫ (8x^3 + 16)4(4x^2) dx = u^5/10 + 16u^3 + C,
where u = 4x^2 and du/dx = 8x.
We can start by making the substitution u = 4x^2. Then, taking the derivative of both sides with respect to x gives du/dx = 8x. Solve for dx, we get dx = du/(8x).
Substituting these expressions
∫ (8x^3 + 16)4(4x^2) dx
= 4∫ (2x^2 + 4)(4x^2) dx
= 4∫ (8x^4 + 16x^2) dx
= 4(8/5 x^5 + 16/3 x^3) + C
= 128/5 x^5 + 64/3 x^3 + C
Substituting back u = 4x^2, we have:
128/5 x^5 + 64/3 x^3 + C = 128/5 (u^5/256) + 64/3 (u^3/16) + C
= u^5/10 + 16u^3 + C
Therefore, the integral can be written as:
∫ (8x^3 + 16)4(4x^2) dx = u^5/10 + 16u^3 + C, where u = 4x^2 and du/dx = 8x.

The question is not correct. you have two linear functions. do you want to know their intersection point?
Step-by-step explanation:
[tex]f(x)=2x-6\\[/tex]
[tex]2x-6=0[/tex]
[tex]2x=6[/tex]
[tex]\frac{2x}{2} =\frac{6}{2\\}[/tex]

234 students in 9 different classrooms. What is the ratio of students to classrooms?
Answer:
26 students per classroom
Step-by-step explanation:
To solve this, the ratio 234 students:9 classrooms must be converted to:
s students:1 classroom
To convert the ratio, 9 was divided by 9 to get 1, and so you must also divide 234 by 9 to maintain the same ratio, which gives us the answer:
26 students: 1 classroom

4. Gabby makes banana bread at her bakery every Monday and Wednesday. Her
banana bread calls for the ratio of ingredients shown
5 cups of sugar for every 50 tablespoons of butter
80 tablespoons of butter for every 32 bananas
Answer:
Top row: 3 cups, 30 tablespoons, 12 bananas
Second row: 7 cups, 70 tbs, 28 bananas
Step-by-step explanation:
The ratio is 5 (sugar) : 50 (butter)...
You can make the unit rate: 1 cup of sugar: 10 tbs of butter
Since the other ratio is 80 tbs : 32 bananas...
1 tbs : .4 bananas
So...
3 cups : 30 tbs
30 tbs : 12 bananas
28 bananas : 70 tbs
70 tbs : 7 cups

Find the value of each trigonometric ratio. Write your answer as a fraction in simplest form. (Example: If the answer is one-half, type 1/2.)
The value of each Trigonometric ratio in a right angle triangle given are; sin X = 4/5 and cos C = 40/41
How to express Trigonometric Ratios?From the attached image, we can see the triangles to find the trigonometric ratios.
Now, the formula for sin and cos in a right angle triangle is;
sin = opposite/hypotenuse
cos = adjacent/hypotenuse.
Thus;
1) sin X = 32/40 = 4/5
2) cos C = 40/41

B. m ≥ -15
C. m ≤ -15
D. m ≤ 15
Answer:
b I think
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
To solve this equation, since m is negative you need to get rid of that negative by dividing each side by -1. this will leave m and make 15, -15. so the equation will be c, m is less than or equal to -15.
A program was created to randomly choose customers at a shoe store to receive a discount. The program claims 15% of the receipts will get a discount in the long run. The manager of the shoe store is skeptical and believes the program's calculations are incorrect. She selects a random sample and finds that 12% received the discount. The confidence interval is 0.12 ± 0.05 with all conditions for inference met.
Part A: Using the given confidence interval, is it statistically evident that the program is not working? Explain.
Part B: Is it statistically evident from the confidence interval that the program creates the discount with a 0.15 probability? Explain.
Part C: Another random sample of receipts is taken. This sample is six times the size of the original. Twelve percent of the receipts in the second sample received the discount. What is the value of margin of error based on the second sample with the same confidence level as the original interval?
Part D: Using the margin of error from the second sample in part C, is the program working as planned? Explain.
Answer:
A: There is no statistical evidence that the program is not working as intended because 0.15 is between the range of 0.12 ± 0.05 = (0.07,0.17)
B: 0.15 is between the range of (0.07,0.17) so it is statistically probable.
C: margin of error=0.05/((6)^(1/2))=0.0204
D: No the program is not working as planned because 0.15 is not within the range of 0.12±0.0204=(0.0996,0.1404)

Answer:
Step-by-step explanation:
1). (8x - 49)° = (5x + 23)°
8x - 49 = 5x + 23
3x = 72
x = 24
2). m∠VST + m∠SVU = 180°
(5(24) + 23)° + m∠SVU = 180°
m∠SVU = 180° - 143°
m∠SVU = 37°
