On some other planet, Thor stands on a bridge and throws his hammer at his brother Loki, who is at ground level. The hammer’s height h (in meters above the ground), t seconds after Thor threw it, is modeled by:
Answer:
h(0) = 3600
t=60 when it hits the ground
max height at 4050
at 15 seconds
Step-by-step explanation:
h(t) = -2t^2 + 60t +3600
When it is thrown is t=0
h(0) = -2(0) +60(0) +3600 = 3600
When it hits the ground is h(t) =0
0 = -2t^2 + 60t +3600
Factor out -2
0 = -2 (t^2 -30t -1800)
Divide by -2
0 = (t^2 -30t -1800)
Factor. What 2 numbers multiply to -1800 and add to -30
0 = (t+30) (t-60)
Using the zero product property
t+30 = 0 t-60 =0
t = -30 t = 60
Since we do not have negative time
t=60
The maximum occurs halfway between the zeros
(-30+60)/2 = 30/2 = 15
Put this into the function to find the maximum value
h(15) = -2(15)^2 + 60(15) +3600
= -2 (225) +900+3600
=4050
Answer:
Thrown at: 3600
Ground after: 60
Max height: 4050
After: 15
Step-by-step explanation:
h(t) = -2t² + 60t + 3600
h(0) = 3600
-2t² + 60t + 3600 = 0
t² - 30t - 1800 = 0
t² - 60t + 30t - 1800 = 0
t(t - 60) + 30(t - 60) = 0
(t - 60)(t + 30) = 0
t = 60, -30(not possible)
h(t) = -2t² + 60t + 3600
-2(t² - 30t) + 3600
-2(t² - 2(t)(15) + 15² - 15²) + 3600
-2[(t - 15)² - 225] + 3600
-2(t - 15)² + 450 + 3600
-2(t - 15)² + 4050

Here is the equation of a circle in standard form.
(x + 10)2 + (y + 9)2 = 100
What are the coordinates of the center?
A. (-10, -9)
B. (9, 10)
C. (-9, -10)
Answer:
A
Step-by-step explanation:
The equation is in the standard form of a circle:
(x – h)^2 + (y – k)^2 = r^2
where (h,k) is the center, and r is the radius.
If we compare the 2 equations:
(x – h)^2 + (y – k)^2 = r^2
(x + 10)^2 + (y + 9)^2 = 100
We can see that the center is (-10, -9).
This is because (x- -10) will become (x+10), and (y- -9) will become (x+9).
So, choice A is correct
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is: [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h, k) is the center and r is the radius.
Here, our equation is: [tex](x+10)^2+(y+9)^2=100[/tex] , which means that h = -10 and k = -9. Then, the center is (-10, -9).

Leia cuts congruent triangular patches with an area of 15 square centimeters from a rectangular piece of fabric that is 10 centimeters long and 6 centimeters wide. How many of the patches can Leia cut from 33 pieces of the fabric?
Answer:
132 patches
Step-by-step explanation:
First we need to find the area of the rectangular piece, multiplying the length and the width:
Area of fabric: 10 * 6 = 60 cm2
If each triangular patch has 15 cm2 of area, a fabric of 60cm2 can make 60 / 15 = 4 triangular patches.
Then, if Leia uses 33 pieces of fabric, she can make a total of 33 * 4 = 132 patches.
Answer:
132
Step-by-step explanation:
Total area'A' of rectangular piece of fabric is given by
A= length 'l' x width'w'
A= 10 x 6=> 60cm²
As there are 33 such pieces, 33 x 60=1980cm²
In order to evaluate the umber of triangles that can be made, divide total area by the area of one triangular piece
n= 1980/15
n=132
Therefore, 132 triangles can be made

AOC and BOD are diameters of a circle, centre O. prove that triangle ABD and triangle DCA are congruent by RHS.
Triangle ABD and triangle DCA can be proven congruent using the RHS congruence criterion.
Explanation:To prove that triangle ABD and triangle DCA are congruent using the RHS (Right Angle, Hypotenuse, Side) congruence criterion, we need to show that they have a right angle, an equal hypotenuse, and an equal side adjacent to the right angle.
Since AOC and BOD are diameters of the circle, we know that they are perpendicular to their respective radii.Therefore, angle AOB is a right angle, and triangle AOB is a right triangle.Since AO and BO are radii of the same circle, they have the same length, making the hypotenuse AB of triangle ABD equal to the hypotenuse BD of triangle DCA.Furthermore, angle ABD and angle CDA are both subtended by the same arc AD, so they are equal in measure.Finally, the adjacent sides to the right angles, AB and DC, are also equal as they are radii of the circle.Therefore, by the RHS criterion, triangle ABD and triangle DCA are congruent.

Finito.
Answer:
(m+6)(m+10).
Step-by-step explanation:
To find this answer, we will need to determine factors of 60 that when added, they are equivalent to 16.
We can begin by listing some factors:
30 and 2
4 and 15
12 and 5
6 and 10
...
Then, we can determine which of these factors can be added together to become 16. From this, we can determine that only factors "6 and 10" become 16 when added together.
When we do this, we can see that only answer 1, (m+6)(m+10), is equivalent to the equation given.
Riley and Jace work at a dry cleaners ironing shirts. Riley can iron 25 shirts per hour, and Jace can iron 30 shirts per hour. Riley worked 3 more hours than Jace and they ironed 460 shirts between them. Write a system of equations that could be used to determine the number of hours Riley worked and the number of hours Jace worked. Define the variables that you use to write the system.
Answer:
25r +30j = 460r - j = 3Step-by-step explanation:
Let r and j represent Riley's hours and Jace's hours, respectively. The equations could be ...
25r +30j = 460
r - j = 3
__
The solution is (r, j) = (10, 7).
The system of equations that could be used to determine the number of hours Riley and Jace worked is: R = J + 3 and 25R + 30J = 460, where R represents the number of hours Riley worked, and J is the number of hours Jace worked.
Explanation:Let's define our variables first. Let's let J represent the number of hours Jace worked and R represent the number of hours Riley worked.
From the information given, we know that Riley worked 3 more hours than Jace. So we can write this as an equation: R = J + 3.
We also know that between them, they ironed 460 shirts. We can express this as another equation by multiplying their per-hour output by the number of hours they worked, then adding the two together: 25R + 30J = 460.
So our system of equations is: R = J + 3 and 25R + 30J = 460.

Synthetic division is a process used to divide a polynomial by a linear expression. Using a step-by-step process, the polynomial 3x^3 - 2x^2 - 7x + 6 is divided by x + 1. The result is a new polynomial, which represents the quotient and a remainder.
Explanation:Synthetic division is used to divide a polynomial by a linear expression. In this case, we have the polynomial (3x^3 - 2x^2 - 7x + 6) and we want to divide it by (x + 1). Synthetic division follows a specific set of steps:
Write the coefficients of the polynomial in a row: 3, -2, -7, 6. Write the root of the divisor, which is the solution to x + 1 = 0. This root is -1. Drop down the leading coefficient, which is 3 in this case. Multiply the root by the number just brought down, and write the result under the next coefficient. So, (-1)*3 = -3. Add the numbers in that column to get the next number to bring down. (-2) + (-3) = -5. Repeat steps 4 and 5 until all coefficients have been processed.
The numbers at the bottom are the coefficients of the quotient polynomial, and the remainder if any.

Mr. Hayes has Ill straw bundles to use for bedding in his horse stalls. What is the
greatest number of stalls he can fill if each stall holds exactly 4 bundles of
straw?
We have been given that Mr. Hayes has 111 straw bundles to use for bedding in his horse stalls. We are asked to find the greatest number of bundles that he can fill if each stall holds exactly 4 bundles of straw.
To solve our given problem, we will divide 111 by 4.
[tex]\text{Greatest number of stalls that can be filled}=\frac{111}{4}[/tex]
[tex]\text{Greatest number of stalls that can be filled}=27.75[/tex]
Since 0.75 is not an integer, so Mr. Hayes cannot fill 0.75 of a stall. Therefore, the greatest possible number of stalls will be 27.
A greengrocers sells mangoes for 77p each.
a)
Find the greatest number of mangoes you can buy for £5.
b) How much change should you receive?
Answer:
6 mangoes
0.38 or 38p
Step-by-step explanation:
Apparently the value of the mango is £ 0.77, which means that to get the number of mangoes you can buy, you must divide this value to the amount of money you have, that is, £ 5
5 / 0.77 = 6.49
which means that it is enough for 6 mangoes.
To know the change, multiply the value of one by 6 and subtract it with £ 5, it would be the change.
6 * 0.77 = 4.62
5 - 4.62 = 0.38
That is, the change is £ 0.38 or 38p
Answer:
(a) 6 mangoes
(b) £0.38
Step-by-step explanation:
(a) The greengocers sell the mangoes for 77 p.
The greatest number of mangoes you can buy for £5 can be gotten by dividing £5 by the price of each mango (77 p). We will only pick the whole number part because number of mangoes can only be whole number.
First, we convert £5 to pence:
£1 = 100 pence
=> £5 = 5 * 100 = 500 pence
Hence, the greatest number of mangoes that can be bought is:
500 / 77 = 6.49
Since we are only picking the whole number part, the answer is 6 mangoes.
(b) The price of 6 mangoes is:
6 * 77 = 462 pence
Hence, if you take £5 (500 pence) to the store, your change should be:
500 - 462 = 38 pence
38 pence is the same as £0.38

A sociologists was investigating the ages of grandparents of high school students. From a random sample of 10high school students, the sociologist collected data on the current ages, in years, of the students' maternal grandparents. A. One of the sociologist's research questions was about the mean difference in age without regard to which grandparent is older. The interval constructed in part (a) does not address such a question. Based on the sample of high school students, give the value of the point estimate for the mean difference in age that could be used to address the sociologist's question.
Answer:
The answer for (a)(-5.96, 2.36) (b) -1.8, since the difference is negative, it can be said or determined that the age of the grandfather is older
Step-by-step explanation:
Solution
(a) From the information given,
n = 10, d =-1.8, sd = 5.81
The 95% confidence interval for the population mean difference age is computed as follows:
CI =d ±tα/2,n-1 (sd/√n)
= -1.8±t₀.₀₅/₂,₁₀₋₁ (5.81/√10)
=-1.8± 2.26 (1.84)
= -1.8 ± 4.16
= (-5.96, 2.36)
Now,
There is a 95% confidence that the mean difference in age of maternal grand parents of high school students lies between - 5.96 and 2.36
(b) The age difference is calculated as the age of grand mother minus age of grand father. the point of estimate for the mean difference is as follows:
Xd = XGM - XGF
= 69.8 -71.6
=-1.8
Therefore, since the difference is negative, it can be said or determined that the age of the grandfather is older
Note: kindly find an attached copy of the complete question and table to this example below.
The mean difference in age between grandparents is calculated by taking the absolute differences between the ages of each pair of grandparents from the sample of students and then averaging those differences.
Explanation:The sociologist's research question about the mean difference in age of grandparents without regard to which one is older requires calculating the absolute difference between the ages of each pair of maternal grandparents for the sample of high school students and then taking the average of those differences. To provide a point estimate for the mean difference in age to address the sociologist's question, let us assume we have the ages of each pair of grandparents for the 10 students. If we denote these age pairs as (G11, G21), (G12, G22), ..., (G110, G210), where G1 and G2 are the ages of the two grandparents for each student, the mean difference in age would be the sum of the absolute differences of these pairs divided by the number of pairs (10 in this case).
Mean Difference = (|G11 - G21| + |G12 - G22| + ... + |G110 - G210|) / 10
Without the actual data, we cannot provide a numerical point estimate, but this is the method that would be used to calculate it.

An A-frame house is 45 feet high and 32 feet wide. Find the measure of the angle that the roof makes with the floor. Round to the nearest degree.
Answer:
Angle, [tex]\theta=70.4^{\circ}[/tex]
Step-by-step explanation:
We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.
The attached figure shows the A frame. Let [tex]\theta[/tex] is the angle that the roof makes with the floor. So,
[tex]\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}[/tex]
So, the angle of 70.4 degrees is the angle that the roof makes with the floor.
Final answer:
To find the angle an A-frame house roof makes with the floor, one needs to use trigonometry. By dividing the width of the house by 2 to work with a right triangle and using the tangent function, the angle is calculated to be approximately 70 degrees.
Explanation:
The question involves finding the angle that an A-frame house roof makes with the floor, given the height of the house is 45 feet and the width is 32 feet. To solve this, we can use trigonometry, specifically the tangent function, as we are dealing with a right-angled triangle where the house's height forms one leg (opposite) and half of the width forms the other leg (adjacent). The formula to find the angle (θ) is θ = arctan(opposite/adjacent).
First, halve the width to work with one side of the A-frame: 32 feet / 2 = 16 feet. Then, use the arctan function: θ = arctan(45 feet / 16 feet). Use a calculator to find θ, which gives us an angle of approximately 70.346 degrees. When rounded to the nearest degree, the angle is 70 degrees.
Therefore, the angle that the roof makes with the floor is 70 degrees.

3(2n + 10) = 54
Divide both sides by 3
2n + 10 = 18
Subtract 10 form both sides
2n = 8
Divide both sides by 2
n = 4
