Hi can someone please help me with this question I've been stuck on it for soooo long!!
Answers
Answer:
Let x=sinθ
2sin²θ = 5sinθ - 3
2x²=5x-3
2x²-5x+3=0
(2x-3)(x-1)=0
2x-3=0 or x-1=0
x=3/2 or x=1
sinθ=2/3 or sinθ=1
θ=arcsin(2/3) or θ=arcsin(1)
θ=0.729727656 or θ=1.57079633=π/2

13. Jessica has taken 8 quizzes. The mean of her scores is 92. Her first 6 scores are shown.
96, 90, 88, 92, 94, 90
If Jessica got the highest score possible on her seventh quiz, what score did she get on her
eighth quiz? What would be her median score Show your work and explain your reasoning.
Answers
Answer: Median= 91; 8th quiz score=86
Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!

Option #2: 32 ÷2
Step-by-step explanation:
Take Note: There are 2 cups in a pint.
Since we are converting cups TO pints.... the number should (logically) be smaller. That eliminates the last two options.
Referring back to our note, it is only sensible to eliminate the first option since there are only 2 cups per pint, NOT 4.
In the end, you should have gotten option 2 which is 32÷2.
PLEASE HELP!!! Area of trapezoids and triangles
Answers
Answer: 54 square inches and 18 square inches
Explanation:
The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.
In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:
[tex]\frac{6+12}{2} *6[/tex]
=[tex]\frac{18}{2} *6[/tex]
=[tex]9*6[/tex]
=54
54 [tex]in.^{2}[/tex] is the answer to the first problem.
Following the same method, we can do the next problem the same way:
[tex]\frac{4+8}{2} *3[/tex]
=[tex]\frac{12}{2} *3[/tex]
=[tex]6*3[/tex]
=18
18 [tex]in.^{2}[/tex] is the answer to the second problem.
Craig wants to put molding around the edge of a rectangular frame that is 8 inches wide and 14 inches long. The molding costs $0.75 per inch. He buys 3 additional inches of molding. What is the total cost?
11.25
25.75
35.25
84.75
please explain your work
Answers
Answer:
$35.25
Step-by-step explanation:
Find the total number of inches needed.
The rectangle has 2 sides of 8 inches and 2 sides of 14 inches.
8 + 8 + 14 + 14 = 44 inches
he also was an additional 3 inches
44 + 3 = 47
Now we can find the total price
47 inches × $0.75 = $35.25

write the inequality shown -4x+y=-3
Answers
The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.
To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.
Starting with -4x + y = -3, we isolate y by adding 4x to both sides:
y = 4x - 3
Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.
If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:
y > 4x - 3
If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:
y < 4x - 3
The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.
For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.
