f(x) = ax² + bx + c a= -8
f(x) = -8x² + bx + c that a controls the direction and the stretch.
So the function will be stretched by 8. The negative represents the direction because, it's negative, it will be facing down.
Not sure how your class describes it but it could be facing down, concaved down, or expands downward.

Given a rational expression, identify the excluded values by finding the zeros of the denominator. x(x+17)
the excluded values for the rational expression x(x+17) are x = 0 and x = -17.
In a rational expression, the denominator cannot be equal to zero because division by zero is undefined. To find the excluded values, we need to find the zeros of the denominator.
In this case, the denominator is x(x+17). To find the zeros, we set the denominator equal to zero and solve for x:
x(x+17) = 0
The equation will be satisfied when either x = 0 or x + 17 = 0.
For x = 0, the expression becomes 0(0+17) = 0, which means division by zero would occur.
For x = -17, the expression becomes -17(-17+17) = -17(0) = 0, which again leads to division by zero.
Therefore, the excluded values for the rational expression x(x+17) are x = 0 and x = -17.

The measures of the three angles of a triangle are in the ratio of 1:2:2. Find their measures.
Answer:
36°, 72°, and 72°
Step-by-step explanation:
The interior angles of a triangle will always add to 180°.
Let's say the smallest angle is x, then the other two angles are both 2x.
x+2x+2x=180
5x=180
x=36
If our angles are x, 2x, and 2x, and we know x is 36, then the answer is:
36°, (2*36)°, and (2*36)°, which equals
36°, 72°, and 72°
Check: 36+72+72=180
calculate the value of m if the lines 3x-my=15 makes an angle of 45° with the line 3x+5y=7please help me to solve this?
To find angle between two lines, we use the formula,
\(\tan \theta=\frac{m_1-m_2}{1+m_1m_2}\)Where
θ is the angle between two lines
m1 is the slope of the first line
m2 is the slope of the second line
First Line Equation:
\(\begin{gathered} 3x-my=15 \\ my=3x-15 \\ y=\frac{3}{m}x-\frac{15}{m} \end{gathered}\)The slope is 3/m
Second Line Equation:
\(\begin{gathered} 3x+5y=7 \\ 5y=-3x+7 \\ y=-\frac{3}{5}x+\frac{7}{5} \end{gathered}\)The slope is -3/5
The angle between the two lines is 45°.
Let's substitute the known information into the formula and figure out the value of 'm':

Suppose you scored 87,77,83, and 83 on on your four exams in a mathematics course. Calculate the range and standard deviation of your exam scores. Round the mean to the nearest tenth to calculate the standard deviation. The range of the exam scores is (Simplify your answer.)
The range of the exam scores is 10, and the standard deviation is approximately 3.4.
The range of a set of values is the difference between the largest and smallest values of the set.
The standard deviation measures the degree of dispersion or variation of a set of values from their mean or central value.
Using the four scores 87, 77, 83, and 83, the range and standard deviation can be calculated below:RangeThe largest score is 87, and the smallest is 77.
Therefore, the range of the exam scores is:Range = Largest score - Smallest score= 87 - 77= 10Standard deviationTo find the standard deviation, first find the mean of the scores:Mean = (87 + 77 + 83 + 83) / 4= 330 / 4= 82.5.
Round the mean to the nearest tenth (one decimal place) to calculate the standard deviation:Standard deviation = √ [(sum of (score - mean)^2) / number of scores)]≈ 3.4
Therefore, the range of the exam scores is 10, and the standard deviation is approximately 3.4.

Consider the following vector field.

sin(x)
(a)
Find the curl of the vector field.
curl(F) =
(b)
Find the divergence of the vector field.
div(F) =
The curl of the vector field
curl(F) = -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k
The divergence of the vector field
div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z
To find the curl of the vector field F(x, y, z) = 9ex sin(y), 2ey sin(z), 8ez sin(x), we need to compute the determinant of the curl matrix.
(a) Curl of F:
The curl of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the following formula:
curl(F) = (∂R/∂y - ∂Q/∂z)i + (∂P/∂z - ∂R/∂x)j + (∂Q/∂x - ∂P/∂y)k
In this case, we have:
P(x, y, z) = 9ex sin(y)
Q(x, y, z) = 2ey sin(z)
R(x, y, z) = 8ez sin(x)
Taking the partial derivatives, we get:
∂P/∂y = 9ex cos(y)
∂Q/∂z = 2ey cos(z)
∂R/∂x = 8ez cos(x)
∂R/∂y = 0 (no y-dependence in R)
∂Q/∂x = 0 (no x-dependence in Q)
∂P/∂z = 0 (no z-dependence in P)
Substituting these values into the curl formula, we have:
curl(F) = (0 - 2ey cos(z))i + (8ez cos(x) - 0)j + (0 - 9ex cos(y))k
= -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k
Therefore, the curl of the vector field F is given by:
curl(F) = -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k
(b) Divergence of F:
The divergence of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the following formula:
div(F) = ∂P/∂x + ∂Q/∂y + ∂R/∂z
In this case, we have:
∂P/∂x = 9e^x sin(y)
∂Q/∂y = 2e^y sin(z)
∂R/∂z = 8e^z
Substituting these values into the divergence formula, we have:
div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z
Therefore, the divergence of the vector field F is given by:
div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z

Step-by-step explanation:
An item sells for $75 and is on sale for 35% off. The sales tax is 9.8%. What is the final cost of the item?
The final cost of the item after a 35% discount and 9.8% sales tax is $53.54.
The given problem is related to percentage discounts and sales tax and can be solved using the following steps:
Step 1: Firstly, we need to determine the discount amount, which is 35% of the original price. Let's calculate it. Discount = 35% of the original price = 0.35 x $75 = $26.25
Step 2: Now, we will calculate the new price after the discount by subtracting the discount amount from the original price.New Price = Original Price - Discount AmountNew Price = $75 - $26.25 = $48.75
Step 3: Next, we need to calculate the amount of sales tax. Sales Tax = 9.8% of New Price Sales Tax = 0.098 x $48.75 = $4.79
Step 4: Finally, we will calculate the final cost of the item by adding the new price and the sales tax.
Final Cost = New Price + Sales Tax Final Cost = $48.75 + $4.79 = $53.54
Therefore, the final cost of the item after a 35% discount and 9.8% sales tax is $53.54.I hope this helps!

In a triangle, one acute angle is 33 degree. The adjacent side of angle 33 degree is 8 and opposite side is x. The largest side of the triangle is 15."/> find the value of x to the nearest tenth
The value of x, to the nearest tenth, is approximately 4.96. The steps involved using the tangent ratio and solving for the unknown side in a right triangle.
In a triangle, the angle opposite to the side x as angle A, and the side opposite to the angle 33° as side B, and the largest side as side C. So we have:
Angle A = 90° - 33° = 57° (since the sum of angles in a triangle is 180°)
Side B = 8
Side C = 15
Side x = ?
Write the formula for the tangent ratio in terms of the sides of the triangle. For angle A, we have:
tangent(A) = opposite/adjacent
Substitute the known values into the formula and solve for the unknown side. Substituting the values we have, we get
tangent(33°) = x/8
Multiplying both sides by 8, we get:
x = 8 * tangent(33°)
Use a calculator to find the value of the tangent of 33 degrees. We get:
tangent(33°) ≈ 0.6494
Substitute the value of the tangent into the formula we obtained in step 3 and solve for x. We get
x ≈ 8 * 0.6494
x ≈ 5.1952
Round the answer to the nearest tenth, since the question asks for the value of x to the nearest tenth. We get
x ≈ 4.96
Therefore, the value of x, to the nearest tenth, is approximately 4.96.

find the area under the normal curve to the left of z plus the area under the normal curve to the right of z. the combined area is
One is the sum of the areas under the normal curves to the left and right of z.
For a normal distribution, the total area under the curve is 1. Therefore, if we can find the area to the left of z, we can subtract it from 1 to find the area to the right of z.
The area to the left of z can be found using a standard normal distribution table or a calculator. For example, if z is 1.5, the area to the left of z is 0.9332.
The area under the entire normal curve is 1. Therefore, the area to the left of z plus the area to the right of z must add up to 1.
Visually, we can think of the normal curve as being symmetric about its mean, which is located at \(z = 0\). As a result, the area to z's left and right are equal. Area to the left of z plus Area to the right of z equals
\(1/2 + 1/2 = 1\) as a result.
\(1 - 0.9332 = 0.0668\)
Therefore, the combined area is:
\(0.9332 + 0.0668 = 1\).
This supports the notion that the entire area under the normal curve is 1.
As a result, the area under the normal curve to the left of z plus the area to the right of z together equal one.
