Final answer:
Savannah drove 144 more miles on Monday than she did on Tuesday, calculated by subtracting Tuesday's mileage from Monday's.
Explanation:
The student is asking how many more miles Savannah drove on Monday than Tuesday. To calculate this, we simply subtract the number of miles driven on Tuesday from the number of miles driven on Monday.
Miles driven on Monday: 716 miles
Miles driven on Tuesday: 572 miles
To find the difference in miles, we use the following equation:
716 miles (Monday) - 572 miles (Tuesday) = 144 miles
Therefore, Savannah drove 144 more miles on Monday than on Tuesday.
The x-intercept of a function y = f(x) are the real solutions of the
equation f(x) = 0.
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.

Mr. Duncan mixed 0.00055 pounds of sulfur and 0.00104 pounds of iron powder in a test tube before heating it. What is the total weight of the mixture in the test tube?
Answer:
1.59 × 10-3 pounds
Step-by-step explanation:
Add the weights of the sulfur and iron powder to find the total weight of the mixture.
First, write both numbers in scientific notation.
Now that both numbers are written in scientific notation, compare the exponents. Since both exponents are not the same, rewrite 5.5 × 10-4 as 0.55 × 10-3. Now the numbers multiplied by the powers of 10 can be added while keeping the power of 10 the same.
So, the total weight of the mixture in the test tube is 1.59 × 10-3 pounds.
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?
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.
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.
what is 6 and 2 thirds minus 2 and 4 fifths?
Answer:

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?
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.

Step-by-step explanation:
Step 1: Factor
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
Step 2: Solve for x
(x - 7)(x + 1) = 0
x - 7 = 0 and x + 1 = 0
x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1
x = 7 and x = -1
Answer: x = 7 and x = -1
A satellite is 6,000 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.
Answer:
3211 miles
Step-by-step explanation:
A right triangle can be used to model the geometry of the problem. One leg of it is the radius of the Earth. The leg at right angles to that is the satellite-to-horizon distance of 6000 miles. The hypotenuse of the triangle is the distance from the satellite to the center of the Earth, so the question will be answered by subtracting the Earth radius from that.
The Pythagorean theorem relates the various distances. Refer to the attachment.
AB² = AD² +BD²
(BC +4000)² = 4000² +6000² . . . . . . . . . . . . use given values
BC +4000 = 1000√(4² +6²) = 2000√13 . . . . take the square root
BC = 2000(√13 -2) . . . . . subtract 4000
BC ≈ 3211.1
The satellite is about 3211 miles from the point directly below it.

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

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
