Given f(x) = 5 – 3x2, use a table to estimate the slope of the tangent line to f at the point P(0,5). 1. Find the slope of the secant line PQ for each point Q(x, f(c) with the x values given in the table. (Round each answer to 6 decimal places if necessary.) 2. Use the answers from the table to estimate the value of the slope of the tangent line at the point P. (Round your answer to the nearest integer.)
The value of the points in the graph is a (2,80).
According to the statement
We have to find that the points on the graph.
So, For this purpose, we know that the
A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
From the given information:
f(x)=[tex]x^{3}[/tex]+6[tex]x^{2}[/tex]+17x+14; slope of the tangent line=5
Then
f(x)=[tex]x^{3}[/tex]+6[tex]x^{2}[/tex]+17x+14
Now find the drivative then
f'(x)=3x^2+12x+17
Then slope of the tangent line=5
Now,
3[tex]x^{2}[/tex]+12x+17 = 5
3[tex]x^{2}[/tex]+12x+12 = 0
[tex]x^{2}[/tex]+4x+4 = 0
Now solve the equation then
[tex]1x^{2}[/tex]+2x+2x+4 = 0
x(x+2) +2(x+2) = 0
(x+2) (x+2) = 0
Here the values of the x become -2,-2.
Then
When x = 2
f(x)=[tex]2x^{3}[/tex]+[tex]6^{2}[/tex]+17(2)+14
f(x)=8+24+34+14
f(x) = 80.
So, The value of the points in the graph is a (2,80).

The function f(x) represents the number of texts sent this week, and g(x) represents the number of texts sent last week. Given f(x) = 6x + 8 and g(x) = 2x − 9, find (f − g)(x) to find how many more texts were sent this week than last week.
(f − g)(x) = 4x − 1
(f − g)(x) = 8x − 1
(f − g)(x) = 4x + 17
(f − g)(x) = 8x + 17
Answer:
(f − g)(x) = 4x + 17
Step-by-step explanation:
find (f − g)(x) = f(x) - g(x)
f(x) = 6x + 8 and g(x) = 2x − 9
6x + 8 - (2x − 9)
multiply the -1 to 2x − 9

A survey of statistics undergraduate at prosperity university completed a survey that asked for their verbal and math sat scores. They wanted to predict the verbal score based on the math score. The value of r-squared was 12. 78%. The least squares regression equation is yhat = 383. 3 + 0. 3489x. Find r.
The coefficient of determination (r-squared) provides an indication of how well the regression model fits the data and the value of r is 0.3574
In this example, the r-squared value is 12.78%, which means that 12.78% of the variation in verbal SAT scores can be explained by the variation in math SAT scores. The least squares regression equation is yhat = 383.3 + 0.3489x, where yhat is the predicted verbal score and x is the math score.
The coefficient of correlation (r) provides a measure of the strength of the linear relationship between two variables. In this example, the coefficient of correlation (r) can be calculated from the coefficient of determination (r-squared) as follows: r = √r-squared = √12.78% = 0.3574.

What is the equation of the line described below written in slope-intercept form?
the line passing through point (2, 2) and perpendicular to the line whose equation is y = x
y = x + 4
y = -x + 4
y = x - 4
The slope of the line perpendicular to y = x is -1. The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept. Substituting m = -1 and using the point (2, 2), we have:
y = -x + b
2 = -2 + b

Most kitchens have a working triangle between the sink (s), the counter (c) and the oven (o). The distance between the sink and oven is 8 feet. The distance between the sink and counter is 6 feet and the distance between the oven and counter is 7 feet. In the kitchen triangle, where is the largest angle?.
Answer:
Step-by-step explanation:
To find the largest angle in the kitchen triangle, we can use the Law of Cosines. The Law of Cosines states that in any triangle with sides a, b, and c and opposite angles A, B, and C, the following relationship holds:
c^2 = a^2 + b^2 - 2ab * cos C
In the kitchen triangle, we have the sides a = 6, b = 7, and c = 8. We can use the Law of Cosines to find the cosine of each angle and then use the inverse cosine function to find the angles themselves:
cos A = (b^2 + c^2 - a^2) / (2bc) = (7^2 + 8^2 - 6^2) / (2 * 7 * 8) = 0.41
A = cos^-1(0.41) = 61.8°
cos B = (a^2 + c^2 - b^2) / (2ac) = (6^2 + 8^2 - 7^2) / (2 * 6 * 8) = 0.95
B = cos^-1(0.95) = 18.4°
cos C = (a^2 + b^2 - c^2) / (2ab) = (6^2 + 7^2 - 8^2) / (2 * 6 * 7) = -0.15
C = cos^-1(-0.15) = 120.0°
The largest angle in the kitchen triangle is C, which measures 120.0°.

The slope of the line that runs through the points (1,5) and (6,2) is -3/5.
What is the slope of the line?Slope is simply expressed as change in y over the change in x.
Slope m = rise / run
The change in y-axis is the rise and the change in x-axis is the run.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Since the line runs through the points (1,5) and (6,2).
Point 1 (1,5)
x₁ = 1y₁ = 5Point 2 (6,2)
x₂ = 6y₂ = 2Plug the given x and y values into the slope formula and simplify.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 2 - 5 )/( 6 - 1 )
Slope m = ( -3 )/( 5 )
Slope m = -3/5
Therefore, the slope of the line is -3/5.

Jamel went on a short trip to visit a friend who lives 19 miles away. The trip there took 1 / 2 of an hour, and the trip back home took 1/5 of
of an hour. What was his
average rate for the trip?
As a fraction, his average rate was
mph.
The total distance traveled was 19 miles and the total time was 3/10 of an hour
The formula for calculating the average rate is distance divided by time, or D/T. In this problem, Jamel traveled 19 miles in a total time of 1/2 + 1/5 = 3/10 of an hour. Using the formula, the average rate can be calculated as 19/3/10 = 19/3 x 10/3 = 190/3 = 63.3 mph. Therefore, Jamel's average rate for the trip was 63.3 mph.
To explain further, when solving a problem involving average rate, it is important to remember the formula D/T. This means that the total distance traveled is divided by the total time. In this problem, the total distance traveled was 19 miles and the total time was 3/10 of an hour. To calculate the average rate, the total distance (19 miles) was divided by the total time (3/10 of an hour). This yielded a result of 190/3, which was further simplified to 63.3 mph.
