Answer:

11t - 5u

Step-by-step explanation:

Given expression,

→ 3t - 4u + 8t - u

Let's solve the given expression,

→ 3t - 4u + 8t - u

Marco is wrong cuz its not repeating

Answer:

  -61/16

Step-by-step explanation:

The version of successive approximation you are using here is one that starts with an interval containing the solution, then cuts that interval in half with each iteration. The end result of each round of iteration is a new approximation to the solution: the midpoint of the smaller interval.

The graph shows the curves cross at a point between x = -4 and x = -3, so the initial interval is [-4, -3]. We have defined the function h(x) = g(x) -f(x) so that h(-4) < 0 and h(-3) > 0. The sign of h(x) will tell which interval limit gets replaced:

  h(x) > 0   ⇒   x replaces the upper limit

  h(x) < 0   ⇒   x replaces the lower limit

The initial estimate of the solution is (-4 +(-3))/2 = -7/2. (iteration 0)

  h(-7/2) > 0, so the interval becomes (-4, -7/2), and the approximate solution after iteration 1 is x ≈ -15/4.

  h(-15/4) > 0, so the interval becomes (-4, -15/4), and the approximate solution after iteration 2 is x ≈ -31/8.

  h(-31/8) < 0, so the interval becomes (-31/8, -15/4) and the approximate solution after iteration 3 is x ≈ -61/16

Additional comment

Note that we don't really care about the function value when we do iteration this way. We only care about the sign of the function value. Other iteration methods use the function values to try to approximate the root. The secant method uses a linear approximation between the function values at the end points of the interval to choose a new value for x.

The distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Given that:

AB = 370 miles

angle A = 24 degrees

BC = 240 miles

angle B = 37 degrees 

To determine the distance from point A to C, we can use the cosine law since we are given two angles and two sides of a regular triangle. 

The angle opposite side AC is angle B which is equal to 37 degrees. 

(AC)^2 =(AB)^2 + (BC)^2 - 2(AB)(BC)cos(B)

Now we have to solve for AC:

(AC)^2 =(370)^2 + (240)^2 - 2(370)(240)cos(37) 

AC = 229.48 miles.

Hence the answer is, the distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Answer: D. quadratic

Step-by-step explanation:

To find an equation for a line that is perpendicular to the line 5x + y = 13 and passes through the point (15, -31), the given line and then find negative reciprocal of that slope to obtain the slope of the perpendicular line.

The given equation is 5x + y = 13. To determine its slope, we can rewrite it in slope-intercept form (y = mx + b), where m represents the slope. Rearranging the equation, we have y = -5x + 13, indicating that the slope of the given line is -5.

The slope of a line perpendicular to another line is the negative reciprocal of its slope. Therefore, the slope of the perpendicular line is 1/5.

Using the point-slope form of a line, which states that y - y1 = m(x - x1), we can substitute the values of the given point (15, -31) and the perpendicular slope (1/5) into the equation. Thus, the equation of the line perpendicular to 5x + y = 13 and passing through (15, -31) is y + 31 = (1/5)(x - 15).

The number of each type of coins are as follows:

q = 15 quarters.

d = 30 dimes.

n = 25 nickels.

In order to solve this word problem, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let d represent the number of dimes.

Let q represent number of quarters.

Let n represent number of nickels.

Let T represent total number of coins.

Note: 1 quarter is equal to 0.25 dollar, 1 nickel is equal to 0.5 dollar, and 1 dime is equal to 0.1 dollar.

Translating the word problem into an algebraic equation, we have;

Dimes; d = 2q     .....equation 1.

Nickels; (70 - (q + 2q)) = (70 - 3q)     .....equation 2.

Total coins; T = n + d + q

0.5(70 - 3q) + 2q(0.1) + q(0.25) = 8.00

Multiplying all through by 100, we have:

5(70 - 3q) + 2q(10) + q(25) = 800

350 - 15q + 20q + 25q = 800

350 + 30q = 800

30q = 800 - 350

30q = 450

q = 450/30

q = 15 quarters.

For the number of dimes, we have:

Dimes, d = 2q

Dimes, d = 2(15)

Dimes, d = 30 dimes.

For the number of nickels, we have:

Nickels, n = (70 - 3q)

Nickels, n = (70 - 3(15))

Nickels, n = (70 - 45)

Nickels, n = 25 nickels.

True: because A significant F test implies that each regression coefficient in a multiple regression model is different from zero.

What does a statistically significant F test indicate in a multiple regression model?

If the F test for overall significance of multiple regression model is statistically significant, it indicates that each regression coefficient (β coefficient) is different from zero.

The F test assesses the joint significance of all the coefficients, determining if the model effectively explains the variability of the dependent variable.

A significant F test suggests that at least one independent variable is related to the dependent variable, implying differences in each regression coefficient.

By comparing the variability explained by the regression model to unexplained variability, the F test evaluates the overall fit of the model.

If the test statistic surpasses the critical value at a chosen significance level, such as 0.05 or 0.01, the null hypothesis is rejected, signifying a substantial overall effect of the model.

Therefore, a statistically significant F test confirms the importance of each regression coefficient and supports the model's ability to explain the dependent variable.

The statement is true.

When the block is in equilibrium, each spring is stretched an additional ∆x. This implies that the forces from the two springs are balanced, and the block is not experiencing any net force in the equilibrium position.

When the block is set into oscillation with amplitude a, it will pass through its equilibrium point during the oscillation. At the equilibrium point, the displacement of the block is zero, and it changes direction. At this point, the block has its maximum speed v, as it is accelerating towards the equilibrium position.

The speed of the block decreases as it moves away from the equilibrium position, reaches zero at the maximum displacement (amplitude), and then starts accelerating towards the equilibrium point again. Therefore, when the block passes through its equilibrium point, it has its maximum speed v.

Answer: $13.00

Step-by-step explanation: If the teacher spent $88 and bought 8 pizzas we first have to find how much they spent on each pizza. We do this by dividing the money by the number of pizzas so 88/8 which leaves us with $11 spent for each pizza. Since each pizza was on sale for $2 off its regular price it means that each pizza was originally $2 more than what the teacher payed for which means the regular price is 11+2 which means each pizza cost $13.

Answer:

2.6 kilometers

Step-by-step explanation:

To find the circumference of a circle, we can use the formula:

Circumference = π * diameter

Given that the diameter of the volcanic crater is 840 meters, we can substitute this value into the formula:

Circumference = π * 840

Using the approximate value of π as 3.14159, we can calculate the circumference:

Circumference = 3.14159 * 840

Circumference ≈ 2643.1796 meters

To convert the circumference to kilometers, we divide the value by 1000:

Circumference in kilometers = 2643.1796 / 1000

Circumference ≈ 2.6432 kilometers

Therefore, the circumference of the rim of the volcanic crater is approximately 2.6 kilometers (rounded to 1 decimal place).
