Find a formula for h(x)h(x)h, left parenthesis, x, right parenthesis. Give an exact expression
The sine function h(x) is given by:
h(x) = 5sin(π/4(x - 0.5)) - 3.
What is the sine function?The cosine function is defined as follows:
g(x) = asin(bx+c)+d.
The coefficients have these following roles:
a: amplitude.b: The period is of 2π/B.c: phase shift.d: vertical shift.For this function, we have that:
The midline is of -3.The minimum value is of -8.Hence the coefficient a is of 5, as:
a = -3 - (-8) = -3 + 8 = 5.
A standard cosine function with amplitude 5 would vary between -5 and 5, with midline at 0, hence the coefficient d is of d = -3.
The minimum value and midline form one-fourth the period, hence, since the period is of 4 x (0.5 - (-1.5)) = 8, we have that:
2π/B = 8
B = π/4
The standard midline is at x = 0, but for this function function it is at x = 0.5, meaning that the function was shifted 0.5 units right, hence c = -0.5.
Thus the function is given by:
h(x) = 5sin(π/4(x - 0.5)) - 3.
The graph at the end of the answer shows that the function has the desired features.

Using supplementary angles, it is found that the measure of angle QRT is of 47º.
What is the missing information?For this problem, we have a straight line segment QS divided by an inclined segment RT. The measures of the angles are given as follows:
m<QRT = 3x + 5.m<TSR = 10x - 7.What are supplementary angles?When two angles have measures adding to 180º, they are called supplementary.
In this problem, due to the inclined segment, angles QRT and TSR are supplementary, and we can solve for x as follows:
3x + 5 + 10x - 7 = 180
13x = 182
x = 182/13
x = 14.
Hence the measure of angle QRT is found as follows:

Find the equation of a line that contains the points (−6,8) and (4,−1). Write the equation in slope-intercept form, using fractions when required.
The slope-intercept form of the equation of the line described is y = -10/9x + 4/3.
Given the following data:
Points on x-axis = (-6, 4).
Points on y-axis = (8, -1).
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Slope = (4 + 6)/-1 - 8)
Slope = -10/9
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
x and y are the points.m is the slope.c is the intercept.At point (-6, 8), we have:
8 = -10/9(-6) + c
8 = 60/9 + c
72 = 60 + 9c
9c = 72 - 60
c = 12/9
c = 4/3
Therefore, the slope-intercept form of the equation of the line described is y = -10/9x + 4/3.

Josiah says to Mia, If you give me $8.50, we will have an equal amount of money." Mia responds, "That may be true, but if you give me $8.50
instead, I will have twice as much money as you." How much money did Josiah and Mia each have in the beginning?
Josiah and Mia have $42.5 and $59.5 in the beginning respectively.
How to find the how much money did Josiah and Mia each have in the beginning?Let us assume x is the amount that Josiah have in the beginning.
y is the amount that Mia have in the beginning.
from the question
if Mia gives $8.50 to the Josiah then both have equal amount which means
y - 8.50 = x + 8.50 ........................(1)
now Mia has double If Josiah gives Mia $8.50 which means
y + 8.50 = 2(x - 8.50)
y + 8.50 = 2x - 17 ..........................(2)
now subtract equation (1) from equation (2)
(y - 8.50) - (y + 8.50) = (x + 8.50) - (2x - 17)
y - 8.50 - y - 8.50 = x + 8.50 - 2x + 17
-17 = -x + 25.5
-x = -25.5-17
x = 42.5
now put x value into equation (1) to obtain y value
y - 8.50 = x + 8.50
y - 8.50 = 42.5 + 8.50
y = 51 + 8.50
y = 59.50
Hence, the Josiah and Mia have $42.5 and $59.5 in the beginning respectively.

The length of a rectangle is three times its width. If the perimeter is 132 inches, what is the length of the rectangle?
1. 48 inches
2. 16.5 inches
3. 49.5 inches
4. 18 inches
Please give an explanation (Do not just give an answer and take points or you will get reported)
Thank you :D
Answer:
Let 2w = the length
P = 2l + 2w
132 = 2(2w) + 2w
132 = 4w + 2w
132 = 6w
22 feet = w
2w = 2(22) = 48 inches
A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all four vertices are equal to 90 degrees.
The length of the rectangle is 49.5 inches.
What is a rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all four vertices are equal to 90 degrees.
We have,
Length of a rectangle = L
Width of the rectangle = W
L = 3W _____(1)
The perimeter of the rectangle:
P = 2 ( L + W )
132 = 2 ( L + W )
132 / 2 = L + W
66 = L + W
From (1),
66 = 3W + W
66 = 4W
66/4 = W
W = 16.5 inches.
From (1),
L = 3 x 16.5
L = 49.5 inches
Thus the length of the rectangle is 49.5 inches.

What is the scatterplot?
We can see that that the data is plotted on a scatterplot. The scatter plot has a vertical and a horizontal axis. It is evident that the horizontal axis plots the time while what is plotted on the vertical axis is the amount of flour.
As we can see, the relationship between the time and the amount of flour is negative. This can be seen from the shape of the plot as it is displayed in the image attached.
Looking at the shape of the graph, we can see that; The amount of flour when the time is zero seconds is 630 grams. As time increases, the amount of flour in the machine decreases. This corresponds to a negative relationship between the two variables.
The negative relationship also implies that we have to expect to have a negative slope. The rate at which the amount of flour increasing is; 210 – 630/3 – 0 = -140 grams/minute

HELP ME 60 POINTS PLEASE HELP ME!!!! Tell me what you know about slope. be as detailed as possible and write in complete sentences in paragraph form. Some examples you can expand on would be slope of parallel and perpendicular lines, finding slope on a graph, using slope formula, etc.
Answer:
The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run. the form of a rise and run looks like a fraction. The slopes of perpendicular lines are negative reciprocals of one another. For example, a line with a slope of 23 will be perpendicular to a line with a slope of −32 . A line with a slope of -5 will be perpendicular to a line with a slope of 15 .
I hope I helped with your essay <3
Answer:
The slope is finding the rate of increase or decrease in a line. The slope of a line can be helpful in multitudes of problems. One example is the fact that if you multiply the slope of two lines that are perpendicular to each other, you get -1. This way, you can find the slope of a perpendicular line without actually having to calculate it. Another way to use slope is with parallel lines. Parallel lines have the same slope and you can find the equation of another parallel lines just by knowing its slope and one point on that line.
The second of two numbers is 5 more than twice the first. Their sum is 80. Find the numbers.
Answer:
The numbers are 25 & 55
Step-by-step explanation:
You can quantify this problem by using x to take the place of the first number. Because x is multiplied by 2 we get 2x, and add 5 since it is 5 more than twice the first. We can add x to 2x+5 which is 3x+5 and set it equal to 80. Then solve for x to get your first number, and subtract 80 from x to get your second number. Your work should look like this.
[tex]x + 2x + 5 = 80\\3x + 5 = 80\\3x = 80-5\\3x = 75\\3x/3 = 75/3\\x = 25\\80 -25 = 55[/tex]

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Area of circle is calculated using formula :
A = πr²
It is given that Area of circle is 2122.64 sq cm. then the radius will be :
A = πr²
2122.64 = π(r)²
r = √2122.64 / π
r = 26 cm
Now, calculating the circumference of the circle using formulae :
C = 2πr
C = 2π x 26
C = 163.36 cm
Therefore, the circumference of circle of area 2122.64 sq cm is 163.36 cm.
