Answers

Answer 1

Answer:

[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] - 7

Step-by-step explanation:

Note the common difference d between consecutive terms in the sequence, that is

d = - 35 - (- 28) = - 42 - (- 35) = - 49 - (- 42) = - 7

Thus to obtain a term in the sequence subtract 7 from the previous term

[tex]a_{n+1[/tex] = [tex]a_{n}[/tex] - 7 with a₁ = - 28

The zeros of f(x) = x2 + 2x - 80 are -10, 8

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.

zero's are nothing but the roots of the equation which by putting in the equation gives zero value.

Given equation is f(x) = x^2 + 2x - 80 solving it to find the zero's by factorization :

f(x) = x^2 + 2x - 80

f(x) = x^2 + 10x-8x - 80

f(x) = x(x+10)-8 (x + 10)

f(x) = (x+10)(x-8)

Now equating it to zero we get

x= -10, 8

Therefore, the zeros of f(x) = x2 + 2x - 80 are -10, 8

The x-intercept of a function y = f(x) are the real solutions of the
equation f(x) = 0.

Answers

the answer is 7 because x=y +f(x) = 0 should equal 179

The given statement "The x-intercept of a function y = f(x) are the real solutions of the equation f(x) = 0." is True because the x-intercepts of a function y = f(x) are points on graph where function crosses x-axis.

At these points, the value of y (f(x)) is equal to 0. In other words, the x-intercepts are the real solutions of the equation f(x) = 0.

To find the x-intercepts of a function, we set f(x) equal to 0 and solve for x. The solutions to this equation will be the x-coordinates of the x-intercepts.

For example, given the function y = 2x - 6, to find the x-intercept, we set y (f(x)) equal to 0:

0 = 2x - 6

Now, solve for x:

2x = 6

x = 6 / 2

x = 3

The x-intercept is (3, 0) since at x = 3, the value of y (f(x)) is 0.

In conclusion, the statement is true. The x-intercepts of a function y = f(x) are the real solutions of the equation f(x) = 0.

What is the slope of the line represented by y = 1 - 8x?

Answers

Answer:

It’s -8

Step-by-step explanation:

Just the number multiplied by x if we have the form y=ax+b or y=b+ax

The slope of a line is represented by the coefficient of the x term in the equation. In the equation y=1−8x, the coefficient of the x term is −8. Therefore, the slope of the line is −8.

Another way to think about the slope of a line is to imagine that the line is a hill. The slope of the hill tells you how steep it is. A positive slope means that the hill is going up, while a negative slope means that the hill is going down. A steeper slope means that the hill is rising or falling more quickly.

In the case of the line y=1−8x, the slope is −8, which means that the line is going down very steeply. For every 1 unit that you move to the right on the x -axis, you move 8 units down on the y -axis.

A soccer goal is 24 feet wide. Point A is 40 feet in front of the center of the goal. Point B is 40

feet in front of the right goal post.

a) find the measure of ∠A and ∠B

b) which angle is larger, ∠A or ∠B?

c) from which point would you have a better chance of kicking the ball into the goal? Why?

Answers

Answer:

a) Angles A and B are 90 degree.

b) The 2 angles are equal

c) From point A having a better chance to kicking the ball in to goal

Step-by-step explanation:

a, b) 2 points are in front of the center and right post of goal. Because there is no detail, we can assume that point A, point B, center of goal, right goal post make up a rectangle. Therefore, the 2 angles are measured equally as 90 degree.

c) Because it's a rectangle, the distance between point A and center of goal is shorter than that between point B and center of goal.

Final answer:

To determine the measures of ∠A and ∠B and identify which is larger, trigonometry is used based on the geometry of the soccer goal and the distances given. ∠A is associated with a larger shooting angle and a better chance of scoring compared to ∠B.

Explanation:

The situation presents a geometry problem involving a soccer goal and positions A and B. To find the measure of ∠A and ∠B, we can visualize the scenario as two triangles with a common side, the 24-foot width of the goal. The distance from the center of the goal to both points A and B is 40 feet. We can use trigonometry to solve for the angles.

For ∠A, we have a right triangle where the width of the goal forms one leg (half is 12 feet, as it is from the center), and 40 feet is the hypotenuse. Applying the cosine function:
cos(∠A) = adjacent / hypotenusecos(∠A) = 12 / 40
Calculating this gives ∠A.

For ∠B, the full width of the goal (24 feet) is the adjacent side of the right triangle, and 40 feet again is the hypotenuse. Therefore:
cos(∠B) = adjacent / hypotenusecos(∠B) = 24 / 40
Calculating this gives ∠B.

Comparing the cosine values will indicate which angle is larger, since a smaller cosine correlates with a larger angle.

From which point would you have a better chance of scoring a goal? Since ∠A is larger, it represents a wider view of the goal, suggesting that kicking the ball from Point A provides a better chance of scoring because you see more of the goal, giving you a larger target area to aim at. This is an application of the concept of shooting angles in soccer.

Answers

The solution to f(x) = g(x) is x = -1.

To find the value of x that satisfies the equation f(x) = g(x), we set the two

functions equal to each other and solve for x.

This gives us the equation -2x + 2 = 4x + 8.

Combining like terms, we get 6x = -6.

Dividing both sides by 6, we find that x = -1.

Therefore, the solution to f(x) = g(x) is x = -1.

Russel wants to buy three ties and a belt and must spend no more that $80. The belt costs $28.50. If three ties are the same price, then how much can he pay for each tie?

Answers

Answer:

About $17.16

Step-by-step explanation:

$80-$28.50= 51.5

Then you divide that by 3 (for the 3 ties)

Russel can spend a maximum of $17.17 on each tie after accounting for the cost of the belt.

To determine how much Russel can spend on each tie, we first need to account for the cost of the belt. The belt costs $28.50 and Russel's total budget is $80. Therefore, the remaining amount for the ties is $80 - $28.50 = $51.50.

Since Russel wants to buy three ties, we need to find the maximum price he can pay for each tie. We can do this by dividing the remaining budget by the number of ties:

$51.50 / 3 = $17.17

Therefore, Russel can spend a maximum of $17.17 on each tie.

In a pair of complementary angles, the measurement of the larger angle is three times that of the smaller angle. Find the measurements of the two angles.

Answers

Final answer:

In a pair of complementary angles, the larger angle is three times the smaller angle. The measurements of the two angles are 22.5 degrees and 67.5 degrees.

Explanation:

In a pair of complementary angles, the larger angle and the smaller angle add up to 90 degrees because complementary angles are two angles that add up to a right angle.

Let's assume the smaller angle is x. According to the given information, the larger angle is three times the smaller angle, so it would be 3x.

Now, we can set up an equation to solve for x. Since the sum of the angles is 90 degrees, we have:

x + 3x = 90

Combining like terms, we find 4x = 90. Dividing both sides by 4, we get x = 22.5.

Therefore, the smaller angle measures 22.5 degrees and the larger angle measures 3 times that, which is 67.5 degrees.
