Answer:
Option C
Step-by-step explanation:
x - 3 = 0
Add 3 to both sides;
x = 3
x + 2 = 0
Subtract 2 from both sides;
x = -2
x - 2 = 0
Add 2 to both sides;
x = 2

Pythagorean Theorem:
25^2=24^2+x
625=576+x^2
49=x^2
x=sqrt49
x=7
Hope this helps!
Merry Christmas!
Answer:
By using the Pythagorean theorem we can solve this
The Pythagorean theorem states that [tex]c^2=a^2+b^2[/tex] where c is the hypotenuse (longest side of the right triangle) and a and b are the other 2 sides. LEts use x to represent the missing side
Therefore,
[tex]25^2=24^2+x^2[/tex]
[tex]625=576+x^2[/tex]
[tex]625-576=576-576+x^2[/tex]
[tex]49=x^2[/tex]
[tex]x=7[/tex]

Which of the following is the function rule for the graph of the sin function from 0 to 2pi if the amplitude is 1.5 and the period is (pi/2)?
A. 1.5sin(pi /4)x
B. 1.5sin2x
C. 1.5sin4x
please help fast, will give brainliest
Answer:
1.5sin4x
Step-by-step explanation:
I just answered this question and got it right.
The function is 1.5sin(4x).
What is sin function?The ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle is the sine function in trigonometry. A right triangle's sides or unknown angles can be found using the sine function.
Given the sine function from (0, 2π), and amplitude is 1.5, the period is π/2
sine function in general form
y = a sin (b (x – h)) + d
where a = amplitude, b= period
h is the phase shift, and
d is the vertical displacement.
according to question, This function currently has no phase shift, since
h = 0, and no vertical displacement, since d = 0
equation is y = a sin b x
and b is ratio of normal period to desired period
b = 2π/(π/2)
b = 4
substitute the value of a and b in equation we get,
y = 1.5 sin (4x)
Hence the sin function from 0 to 2pi is y = 1.5 sin (4x).

identify the angles that each have a measure of 88
Answer:
∠1=∠88(Vertically Opposite angles are equal)
∠8=∠88(corresponding angles are equal)
∠3=∠88(alternate interior angles are equal
Angles ∠1, ∠3 and ∠8 are equal to 88°.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Angle 1 and 88 are the vertically opposite angle, so they are equal
∠1 = 88°
Angle 1 and angle 3 are corresponding angle, so they are equal
∠1 = ∠3 = 88°
Angle 3 and 8 angle are vertically opposite angle, so they are equal
∠3 =∠8 = 88°

There is a sale at your favorite clothing store. They have their jeans priced at $49.99 with a extra 20% off. How much will you pay for three pairs of jeans, not including tax? Exlpain how you got your answer.
Answer: You need to pay $119.98 for three pairs of jeans.
Step-by-step explanation:
Market price of 1 jeans = $49.99
Discount percent = 20% = 0.20
Market price for 3 jeans = 3 x ($49.99)
= $ 149.97
Discount price = 20% of (Market price for 3 jeans )
= .0.20 x ($149.97)
= $ 29.99
Price of 3 jeans after discount = (Market price for 3 jeans ) - ( Discount price)
= $ (149.97 - 29.99)
= $ 119.98
Hence, you need to pay $119.98 for three pairs of jeans.
Which pair of triangles MUST be similar?
A. Triangle 5 has a 25 degree angle and a 75 degree angle. Triangle 6 has a 25 degree angle and a 70 degree angle.
B. Triangles 1 and 2 each have a 40 degree angle.
C. Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.
D.Triangles 3 and 4 are both scalene. Each have a 65 degree angle.
Answer:
C
Step-by-step explanation:
The total measurement of a triangle is 180
Triangle 7 has a 40 degree angle and 35 degree angle.
40+35=75
180-75=105
Triangle 8 has the same angle that is 40 degrees and 105. And if you do the same math, you would get 35 for the missing angle of triangle 8

A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can't quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon. If he has $42.80 in his wallet, which equation represents the amount of money he may have after he sees Rita? |x – 42.80| = 12
Answer:
|x - 42.80| = 12
Step-by-step explanation:
The absolute value |x - a| = b means either x - a = b or x - a = -b
Let x represent the amount of money in the afternoon after he has either paid her back or she has paid him.
Given that he has $42.80 in his wallet and he either borrowed $12 from his friend Rita or she borrowed $12 from him. Therefore:
x = 42.80 + 12; or x = 42.80 - 12
Hence:
x - 42.80 = 12; or x - 42.80 = -12
|x - 42.80| = 12

A museum requires a minimum number of chaperones proportional to the number of students on a field trip. The museum requires a minimum of 333 chaperones for a field trip with 242424 students.
Answer: See explanation
Step-by-step explanation:
Here is the complete question:
A museum requires a minimum number of chaperones proportional to the number of students on a field trip. The museum requires a minimum of 3 chaperones for a field trip with 24 students. Which of the following could be combinations of values for the students and the minimum number of chaperones the museum requires? Choose 2 answers.
A. Students: 72
Minimum of chaperones: 9
B. Students: 16
Minimum of chaperones: 2
C. Students: 60
Minimum of chaperones: 6
D. Students: 45
Minimum of chaperones: 5
E. Students: 40
Minimum of chaperones: 8
Since the museum requires a minimum of 3 chaperones for a field trip with 24 students. This means that there will be 24/3 = 8 students per chaperone.
We then divide the number of students given in the question by the number of chaperone to know our answers. This. Will be:
Students: 72
Minimum of chaperones: 9
This will be: 72/9 = 8
Therefore, this is correct.
B. Students: 16
Minimum of chaperones: 2
This will be: 16/2 = 8
This is correct
C. Students: 60
Minimum of chaperones: 6
This will be: = 60/6 = 10.
Therefore, this is wrong
D. Students: 45
Minimum of chaperones: 5
This will be 45/5 = 9
Therefore, this is wrong.
E. Students: 40
Minimum of chaperones: 8
This will be: 40/5 = 8.
Therefore, this is wrong.
Therefore, options A and B are correct.

F. The relationship between x and y is not a straight line.
Does anyone know the answer??
Answer:
[tex]y=\frac{1}{3}x-1[/tex]
As the line equation represents a straight line, so the relationship between x and y is a straight line.
Therefore, option E is true.
Step-by-step explanation:
Taking two points from the given line
(3, 0)(-3, -2)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(3,\:0\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-2\right)[/tex]
[tex]m=\frac{-2-0}{-3-3}[/tex]
[tex]m=\frac{1}{3}[/tex]
From the graph, the y-intercept can be calculated by setting the x=0 and then check the corresponding value of y.
at x = 0, y=-1
Thus, the y-intercept = -1
We know that the slope-intercept form is
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept
substituting the values of m=1/3 and the y-intercept b = -1
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{3}x+\left(-1\right)[/tex]
[tex]y=\frac{1}{3}x-1[/tex]
As the line equation represents a straight line, so the relationship between x and y is a straight line.
Therefore, option E is true.

Rectangle FGHJ has coordinates F(-8, 6), G(8, 6), H(8,-6), and J(-8, -6). The rectangle is dilated by a scale factor of v with the origin as the center of dilation to form rectangle F'G'H'J'. Which ordered pair represents the coordinates of vertex H'?
Answer:
H'(8v,-6v)
Step-by-step explanation:
Here coordinate of H is (8,-6). We are dilating it using the rule (x,y)-->(kx,ky) where 'k' is scale factor.
For our problem , the dilation factor is "v"
So, image would be (8v,-6v)
