Answer:
[tex]Sin\theta =\frac{-5}{\sqrt{61}}[/tex]
Step-by-step explanation:
(6, -5)
According to the diagram
[tex]OA^{2}=OB^{2}+AB^{2}[/tex]
[tex]OA^{2}=6^{2}+5^{2}=36+25=61[/tex]
[tex]OA=\sqrt{61}[/tex]

Prove that the lines x+y=5, 2x–y=16 and x+2y=3 intersect at one point. What are the coordinates of this point?
Answer:
The coordinates of the intersection point are [tex](7,-2)[/tex]
Step-by-step explanation:
we have
[tex]x+y=5[/tex] -----> equation A
[tex]2x-y=16[/tex] -----> equation B
[tex]x+2y=3[/tex] -----> equation C
we know that
If the system of equations intersect at one point, then the system of equations has one solution
using a graphing tool
see the attached figure
The coordinates of the intersection point are [tex](7,-2)[/tex]
This point is a common solution for the three equations
Verify
Substitute the value of [tex]x=7, y=-2[/tex] in each equation
so
Equation A
[tex]x+y=5[/tex]
[tex]7-2=5[/tex]
[tex]5=5[/tex] ----> is true, therefore the point is a solution of the equation A
Equation B
[tex]2x-y=16[/tex]
[tex]2(7)+2=16[/tex]
[tex]16=16[/tex] ----> is true, therefore the point is a solution of the equation B
Equation C
[tex]x+2y=3[/tex]
[tex]7+2(-2)=3[/tex]
[tex]3=3[/tex] ----> is true, therefore the point is a solution of the equation C
The time required for a skilled worker to produce x shirts is given by the function T(x) = 4x + 2, where T is measured in hours. The salary the she is paid is given by the function S(T) = 15T, where S is measured in dollars.
A. If the worker produces 18 units, what will she be paid?
B. How many units would the worker need to produce to be paid $3,030?
Answer:
A. $1,110
B. 50 units.
Step-by-step explanation:
A. Substitute [tex]x=18[/tex] into the function [tex]T(x)=4x+2[/tex] for calculate the time in hours required for the worker to produce 18 units:
[tex]T(18)=4(18)+2=74[/tex]
Now you need to substitute [tex]T=74[/tex] into the function [tex]S(T)=15T[/tex] to calculate the amount in dollars she will be paid for 74 hours:
[tex]S(74)=15(74)=1,110[/tex]
She will be paid $1,110.
B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute [tex]S(T)=3,030[/tex] into the function [tex]S(T)=15T[/tex] and solve for T (to find the number of hours she requires to work to be paid $3,030)
[tex]3,030=15T\\\\T=\frac{3,030}{15}\\\\T=202[/tex]
Now, substitute [tex]T(x)=202[/tex] into [tex]T(x)=4x+2[/tex] and solve for x, to calculate the number of units she produces in 202 hours:
[tex]202=4x+2\\\\202-2=4x\\\\x=\frac{200}{4}\\\\x=50[/tex]
She would need to produce 50 units to be paid $3,030

So first you will multiply the terms with the same base by adding their exponents. Then solve the exponents. Then the only thing you will have left is 7 to the power of 0. Which equals 1
a point occupies zero dimensions true or false
Answer: True.
Step-by-step explanation:
In geometry , we have three undefined terms as :
1) point [ no dimension]
2) line [ one dimension]
3) plane [ two dimension]
A point is just a tiny mark on Cartesian plane which has no length like a line , no width and area like a plane or no volume like a three dimensional shape . We can use only its location but cannot measure it.
Hence, it has no dimension.
Hence, the given statement "a point occupies zero dimensions" is a true statement.
Answer:true

1/2- 1/4 write in simplest form
Answer:
The answer is 1/4 Also if your having a hard time with fractions use calculator soup its easy thats what i use
Step-by-step explanation:
The simplest form of the expression 1/2 - 1/4 is 1/4.
To simplify the expression 1/2 - 1/4, we first need to find a common denominator, which is the same denominator that both fractions share. In this case, the common denominator is 4.
To make 1/2 have a denominator of 4, we need to multiply both the numerator and denominator by 2. This gives us (1 * 2) / (2 * 2), which simplifies to 2/4.
So, the expression becomes 2/4 - 1/4. Now that both fractions have the same denominator, we can subtract their numerators while keeping the denominator the same:
(2 - 1) / 4 = 1/4
Therefore, the simplified form of 1/2 - 1/4 is 1/4. This means that if you have half (1/2) of something and you subtract a quarter (1/4) from it, you are left with one-quarter (1/4) of that something.
Simplifying fractions is essential in mathematics because it helps express quantities in their most reduced and straightforward forms, making them easier to work with and understand. In this case, 1/2 - 1/4 simplifies to 1/4, representing a clear and concise result.

Apply the distributive property to simplify the expression. -7(4x-3)
Answer:
Step-by-step explanation:
(-7*4x)(-7*-3)
-28x+21
Thats the answer
To simplify the expression -7(4x-3), distribute -7 to each term inside the parentheses and multiply. The simplified expression is -28x + 21.
Explanation:To simplify the expression -7(4x-3) using the distributive property, you need to distribute the -7 to each term inside the parentheses. This means multiplying -7 by both 4x and -3.
The product of -7 and 4x is -28x, and the product of -7 and -3 is 21.
Therefore, the simplified expression is -28x + 21.

find the surface area of this triangular prism
To find the surface area, find the area of each side and then add them together.
The bottom is 8 x 2 = 16
The left side is 6 x 2 = 12
The slanted side is 10 x 2 = 20
The front triangle is 1/2 x 8 x 6 = 24
The back triangle is the same as the front = 24
Total surface area = 16 + 12 + 20 + 24+24 = 96 square inches.

Solve x2 + 10x = 24 by completing the square. Which is the solution set of the equation? {–12, 2} {–2, 12}
Answer: I could be wrong so don't get your hopes up but I believe the solution set would be {-2,12}
Step-by-step explanation:
Answer:
The solution set is {-12,2}.
Step-by-step explanation:
We have given a quadratic equation.
x² + 10x = 24
We have to find the solution of above equation by completing square.
Adding (5)² to both sides of above equation, we have
x²+10+(5)² = 24+ (5)²
(x+5)² = 24+25
(x+5)² = 49
Taking square root to both sides of above equation, we have
x+5 = ±7
x+5 = 7 or x+5 = -7
x = 7-5 or x = -7-5
x = 2 or x = -12
Hence, the solution set is {-12,2}.
A standard deck of 52 cards has four 13-card suits: diamonds, hearts, clubs, and spades. The diamonds and hearts are red, and the clubs and spades are black. Each 13-card suit contains cards numbered from 2 to 10, a jack, a queen, a king, and an ace. The jack, queen, and king are called face cards.
Roger drew one card from a standard deck of 52 cards. What is the probability that the card Roger drew is not red?
Answer:129
Step-by-step explanation:you just have to add them together
Final answer:
The probability that the card drawn by Roger from a standard deck is not red is 50%, as exactly half of the cards in a standard deck are black (non-red).
Explanation:
The student has asked what the probability is that a card drawn from a standard deck of 52 cards is not red. Given that half the cards are red (diamonds and hearts) and the other half are black (clubs and spades), we can easily calculate this probability.
Since there are 26 black cards (13 clubs and 13 spades) out of a total of 52 cards, the probability of drawing a black card is 26 out of 52, which can be simplified to 1/2 or 0.5. Therefore, the probability that Roger draws a card that is not red is 50%.

hi
The number of more people who felt a stabbing pain than a stomach ache when they are hungry is obtained by subtracting the number of people who felt a stomach ache from the number of people who felt a stabbing pain. The difference, which is 19, indicates that 19 more people felt a stabbing pain.
Explanation:The subject of the question is simple subtraction in mathematics. In this scenario, find the difference between the number of people who felt a stabbing pain when they were hungry and the number who felt a stomach ache. The number of people who felt a stabbing pain is 49, and the number of people who felt a stomach ache is 30. So, to obtain the number of more people feeling stabbing pain than stomach ache: 49 (stabbing pain) - 30 (stomach ache) = 19. Thus, 19 more people felt a stabbing pain than a stomach ache when they were hungry.
