write a sine function that has a midline of 3, an amplitude of 2 and a period of 3pi/4
Answer:2sin(8/3x)+3
Step-by-step explanation:
The required sine function is [tex]\bold{y=2~sin(\frac{3\pi}{4} x)+3}[/tex]
What is midline?"It is the horizontal center line about which the function oscillates above and below. "
What is amplitude?"It is the distance between the highest point and midline."
What is time period?"It is the length of one complete cycle of the curve."
What is vertical shift?"It is the distance between midline and x-axis."
What is equation of sine graph?"The generalized equation for a sine graph is as follows:
[tex]y = A~sin(B(x + C)) + D[/tex]
where, amplitude = A
period = 2π/B
phase shift = C
vertical shift = D"
For given function,
A sine function that has a midline of 3, an amplitude of 2 and a period of 3pi/4
A = 2
T = [tex]\frac{3\pi}{4}[/tex]
In this case, the midline is 3
⇒ D = 3
Using the generalized equation of sine function,
[tex]\Rightarrow y = A~sin(B(x + C)) + D\\\\\Rightarrow y = 2~sin(\frac{3\pi}{4} (x + 0)) + 3\\\\\Rightarrow y=2~sin(\frac{3\pi}{4} x)+3[/tex]
Therefore, the required sine function is [tex]\bold{y=2~sin(\frac{3\pi}{4} x)+3}[/tex]

Calculate the area of triangle ACD.
You must show all your working.
Answer:
216 cm²
Step-by-step explanation:
Area of ∆ACD = ½*CD*CA
CD = 24 cm
CA = ?
Use pythagorean theorem to find CA.
Thus:
CA² = AB² + BC²
Substitute
CA² = 10.8² + 14.4² = 324
CA = √324
CA = 18 cm
Area of ∆ACD = ½*CD*CA
Substitute
Area = ½*24*18

Answer:
O.75
Step-by-step explanation:
The value of x in the equation 1.5(4)^2x is equal to 12 is 3/4 after equation the power of same base.
What is integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have an equation:
[tex]\rm 1.5(4)^2^x=12[/tex]
[tex]\rm (4)^2^x=8[/tex]
[tex]\rm (2^2)^{2x}= 2^3[/tex]
[tex]\rm 2^{4x}=2^3[/tex]
4x = 3 (equating powers of same base)
x = 3/4
Thus, the value of x in the equation 1.5(4)^2x is equal to 12 is 3/4 after equation the power of same base.

Triangle ABC has coordinates A(-3, 2), B(-2, 4), and C(-2, 1). If the triangle is reflected over the y-axis, what are the coordinates of A'?
Answer:
A=3, 2
B= 2,4
C= 2, 1
If i'm not wrong
Point A(-3,2)) reflected over the y-axis becomes: A'(3,2).
Point B(-2,4) reflected over the y-axis becomes: B'(2,4).
Point C(-2,1) reflected over the y-axis becomes: C'(2,1).

Jose' traveled from his home in Ocala to Gainesville. Gainesville is 37 miles
due north of Ocala. North is considered a positive direction and south is
considered a negative direction. What integer value would represent the
direction and the distance as Jose's traveled back home from Gainesville to
Ocala?
Pls help!!!!!!
Answer:
The integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.
Step-by-step explanation:
The direction is represented by the sign that accompanies the distance, since Jose is returning from Gainesville, then the direction must represented by a minus sign (-), since he is travelling southwards. The distance is the magnitude of the length covered by Jose during his return. Hence, distance is represented by the natural number 37.
Finally, the integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.
Sheldon spins the two spinners below one time what are the chance he will spin 3 or c ?
Answer:
[tex]P(3\ or\ c) = 0.45[/tex]
Step-by-step explanation:
Given
See attachment for spinner
Required
[tex]P(3\ or\ c)[/tex]
From the first spinner, we have:
[tex]S = \{1,2,3,4,5\}[/tex] --- Sample Space
[tex]n(S)=5[/tex]
So, P(3) is:
[tex]P(3) = \frac{n(3)}{n(S)}[/tex]
[tex]P(3) = \frac{1}{5}[/tex]
[tex]P(3) = 0.20[/tex]
From the second spinner, we have:
[tex]S = \{a,b,c,d\}[/tex]
[tex]n(S) = 4[/tex]
So, P(c) is:
[tex]P(c) = \frac{n(c)}{n(S)}[/tex]
[tex]P(c) = \frac{1}{4}[/tex]
[tex]P(c) = 0.25[/tex]
The required probability is then calculated as:
[tex]P(3\ or\ c) = P(3) + P(c)[/tex]
[tex]P(3\ or\ c) = 0.20 + 0.25[/tex]
[tex]P(3\ or\ c) = 0.45[/tex]

The answer to the above question
Answer:
Step-by-step explanation:
Since our interval is given as it is, we are in QIII. That interval is equivalent to 270 degrees to 360 degrees, which is QIII. If we draw this right triangle in QIII and label it accordingly, the side adjacent to the reference angle is sqrt2 and the hypotenuse is 2. We know this because the cosine ratio is defined as the side adjacent to the reference angle over the hypotenuse of the right triangle. That means that we have to find the missing side in order to determine the other 2 main trig ratios. Using Pythagorean's Theorem, we have
[tex]2^2=\sqrt{2}^2+b^2[/tex] and
[tex]4=2+b^2[/tex] so
[tex]b=\sqrt{2}[/tex]. But since it is for a value that, in QIII is negative, it is [tex]-\sqrt{2}[/tex]
Now we can find the sin and tan of that reference angle. Sin is defined as the side opposite the reference angle over the hypotenuse, so
[tex]sin\theta=\frac{-\sqrt{2} }{2}[/tex] and tan, which is defined as side opposite the reference angle over the side adjacent to the reference angle, then
[tex]tan\theta=\frac{-\sqrt{2} }{\sqrt{2} }=-1[/tex]

if n is an integer,what is the sum of the next three consecutive even integers greater than 2n?
Answer:
6n + 12
Step-by-step explanation:
Given an integer n, the 3 consecutive even integers greater than 2n are 2n+2, 2n+4 and 2n+6
Taking their sum;
Sum = (2n+2)+(2n+4)+(2n+6)
Sum = 2n+2n+2n+2+4+6
Sum = 6n + 12
Hence the sum of the 3 consecutive even integers greater than 2n is 6n+12
