The graph of which function has an amplitude of 3 and a right phase shift of ?
y = 3+ sin 2(x - 5)
y = 3sin 2(2
y = 3+ sin 2 (2+)
y = 3sin 2(x + 5)
Answer:
Option 4
Step-by-step explanation:
Equation representing the sine function is,
y = Asin[B(x- C)] + D
Here, A = Amplitude
B = [tex]\frac{2\pi }{\text{Period}}[/tex]
C = Phase shift
D = Vertical shift
If the amplitude of the the given function = 3 and right phase shift = [tex]\frac{\pi }{4}[/tex]
Therefore, equation of the sine function will be,
[tex]y=3\text{sin}B(x-\frac{\pi }{4})+D[/tex]
By comparing this equation with the given options,
Equation representing right phase shift = [tex]\frac{\pi }{4}[/tex] and amplitude = 3,
[tex]y=3\text{sin}2(x-\frac{\pi}{4})[/tex]
This equation represents right phase shift = [tex]\frac{\pi }{4}[/tex] and amplitude = 3.
Therefore, Option 4 is the correct option.

Passes through
(-8, 3) and (8, -1).
Answer:
Slope = Y2 -Y1 / X2 - X1
Slope = -1 -3 / 8 --8
Slope = -4 / 16
Slope = -1 / 4
To calculate the equation we fill in this equation:
(y - y1) = slope • (x -x1)
We only need to choose 1 point so we'll choose (-8, 3)
(y - 3) = -1 / 4 * (x --8)
So the Equation equals
y = -1 / 4 x -2 + 3
y = -1 / 4x +1

Given L || M find the value of unknown angles in each of the following figures
Answer:
x = 120°
y = 60°
Step-by-step explanation:
✔️since, lines l and m, area parallel, therefore,
x = 120° (they are corresponding angles having matching corners. Thus, corresponding angles are congruent to each other)
✔️x + y = 180° (linear pair angles)
Plug in the value of x
120 + y = 180
Subtract 120 from each side of the equation
y = 180 - 120
y = 60°

Which expression can be simplified as 1/18n? (n2)9. (n^-9)-2. (n^-6)-3. (n^-6)-3. (n-3)^6
Answer:
[tex]\frac{1}{n^{18}} = (n^{-3})^6[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{n^{18}}[/tex]
Required
Determine its equivalent
[tex]\frac{1}{n^{18}}[/tex]
Express 18 as 3 * 6
[tex]\frac{1}{n^{18}} = \frac{1}{(n^{3})^6}[/tex]
This can be rewritten as:
[tex]\frac{1}{n^{18}} = (\frac{1}{n^{3}})^6[/tex]
Apply the following law of indices:'
[tex]\frac{1}{a^b} = a^{-b}[/tex]
[tex]\frac{1}{n^{18}} = (n^{-3})^6[/tex]
Hence;

Solve for x. 3X - 4 3X - 8
Answer:
x = 2
As x = 12/6 = 2
Step-by-step explanation:
3x-4+3x-8
3x+3x-4-8
= 6x-12
FACTORISING for check and set to zero
6(x-2)
6x -12 = 0
Cancel out left by adding 12 to both sides then applying /6 to both sides to cancel 6 left side.
6x--12 + 12 = 0 + 12
6x / 6 = 12 / 6
x = 12/6
x = 2
or balance as grouping by separation = multiply at end by -1
3x+3x = --4 - 8
6x = - 12
x = - 12/6
x = - 2
x = - 2 ( -1 )
x = 2

Two cards are drawn from a standard deck of cards without replacement. Find the probability of drawing a heart and a club in that order
Answer:
4/663
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Since we are to draw from a pack of card, the total outcome will be 52
Since there are 4 hearts;
Pr(selecting heart) = 4/52 = 1/13
If a club is then selected without replacement, the total number of card remaining will be 51;
Pr(selecting a heart) = 4/51
probability of drawing a heart and a club in that order = 4/52 * 4/51
probability of drawing a heart and a club in that order = 16/2652
probability of drawing a heart and a club in that order = 4/663
a family buys a new home for $212,500 and pays a 20% down payment ($42,500). if the mortgage is for 15 years at 5.75% interest which is their monthly house payment
Answer:
Their monthly house payment is of $2,184.65.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
A family buys a new home for $212,500 and pays a 20% down payment ($42,500).
This means that the loan is of 212,500 - 42,500 = $170,000, that is, [tex]P = 170,000[/tex]
Value of the loan in 15 years:
15 years means that [tex]t = 15[/tex]
5.75% interest means that [tex]r = 0.0575[/tex]
Compounded yearly, so [tex]n = 1[/tex]
Then
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(15) = 170000(1 + \frac{0.0575}{1})^{15}[/tex]
[tex]A(15) = 393237[/tex]
Monthly payment:
Total of $393,237 in 15*12 months. So
[tex]M = \frac{393237}{15*12} = 2184.65[/tex]
Their monthly house payment is of $2,184.65.
If 10^x = 5, what is x?
Answer:
x=0.69897009
Step-by-step explanation:
expand by logarithms
10^x=5
=log(10^x)=log(5)
=x log(10)=log (5)
log base 10 of 10 is 1
x.l =log(5)
multiple bothside by 1
x=log(5)
x=0.6989709
What is the slope of a line that is perpendicular to the graph of the function below.
Y=1/4x-3
Answer:
The slope of a line that is perpendicular to y=1/4x-3 is -4/1x
Step-by-step explanation:
To get a perpendicular line you need to have a slope that is opposite of the other line and the opposite of 1/4 is -4/1x
If cos(2/3x+20)°=sin(2x−10)°, find the acute angles of the corresponding right triangle.
A =
B =
Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50

Answer:
about 75.36
Step-by-step explanation:
we know the radius of the base (circle) is 2 since 4/2 is 2.
Area of cylinder is height times area of base
6*4π=24π
You round π as 3.14
so 3.14*24= 75.36
Answer:
[tex] 75.4 \: {cm}^{3} [/tex]
Step-by-step explanation:
Height of the cylinder h = 6 cm
Diameter d = 4 cm
Radius r = 4/2 = 2 cm
[tex]V_{cylinder} = \pi {r}^{2} h \\ \\ = 3.14 \times {(2)}^{2} \times 6 \\ \\ = 3.14 \times 4 \times 6 \\ \\ = 3.14 \times 24 \\ \\ = 75.36 \\ \\ = 75.4 \: {cm}^{3} [/tex]
This line plot shows how many miles Monique rode her bike this week.
Answer:
151
Step-by-step explanation:
Answer:
152 miles
Step-by-step explanation:
There are 2 Xs above 20 1/2, so she rode that distance twice. There are 3 Xs above 22 1/2, so she rode that distance three times. The other distances with Xs she only did once. We add up the distances for each X to get the total:
20.5 + 20.5 + 21.5 + 22 + 22.5 + 22.5 + 22.5 = 152 miles
What are the two roots of the quadratic equation? y=x squared-3x-4
Answer:
{x | x ∈ R, 4,-1}
Step-by-step explanation:
[tex]y=x^2-3x-4[/tex]
[tex]y=x^2+x-4x-4[/tex]
[tex]y=(x^2+x)+(-4x-4)[/tex]
[tex]y=x(x+1)+(-4)(x+1)[/tex] Distributive property
[tex]y=(x+(-4))(x+1)[/tex] Distributive Property
[tex]y=(x-4)(x+1)[/tex]
set y to 0
[tex]0=(x-4)(x+1)[/tex]
set the factors to 0
[tex]0=x-4; 0=x+1[/tex]
[tex]4=x; -1=x[/tex]
