Answer:
e. It will take 11 seconds to reach the maximum height of 1,936 feet.
f. It will take 22 seconds to return to the earth.
Step-by-step explanation:
Given:
Initial velocity [tex]v_0[/tex] = 352 ft/sec
Solving for question e.
To find the time required to reach the maximum height we will use the formula,
[tex]h(t) = -16t^2+v_0t+h_0[/tex],
where [tex]v_0[/tex] is the starting velocity
[tex]h_0[/tex] is the initial height.
Using the velocity and starting height from our problem we have,
[tex]h(t) = -16t^2+352t+0[/tex],
The path of this rocket will be a downward facing parabola, so there will be a maximum.
This maximum will be at the vertex of the graph.
To find the vertex we start out with [tex]x= \frac{-b}{2a}[/tex] which in our case is,
[tex]x=\frac{-352}{2(-16)}=\frac{-352}{-32}= 11[/tex]
So, It will take 11 seconds for the rocket to reach its maximum height.
We will find maximum height using the formula by substituting value of t we get,
[tex]h(11)=-16(11^2)+352(11)+0\\h(11) = -16 \times121+ 352 \times 11 = -1936+3872= 1936 \ ft[/tex]
Hence the maximum height will be [tex] 1936 \ ft[/tex]
Now Solving for question f.
To find the time required for rocket to reach earth.
We will set our formula to 0 to find the time.
[tex]0= -16t^2+352t+0\\-16t(t-22)=0[/tex]
Using the zero product property, we know that either -16t = 0 or t - 22 = 0. When -16t = 0 is at t = 0, when the rocket is launched. t - 22 = 0 gives us an answer of t = 22.
So the rocket reaches the Earth again at 22 seconds.
13 lb7 oz + 10 lb2 oz
Final answer:
The sum of the two weights, 13 lb 7 oz and 10 lb 2 oz, is 23 lb 9 oz. You add the ounces first, which don't need conversion, and then add the pounds.
Explanation:
Adding Pounds and Ounces
The question involves adding two weights together that are given in pounds and ounces. To do this, we need to add the ounces together first and then the pounds. The sum of 7 ounces and 2 ounces is 9 ounces. Since there are 16 ounces in one pound, we have no need to convert these ounces to pounds. The sum of 13 pounds and 10 pounds is 23 pounds. Therefore, when we combine these two sums, we arrive at the total weight of 23 pounds and 9 ounces.
A stove that cost $500 will be on sale next week for 25% off it’s regular price what is the amount of savings
Final answer:
To calculate the savings of 25% off a $500 stove, you multiply 500 by 0.25 to get a savings of $125.
Explanation:
The question asks us to calculate how much money will be saved on a stove that is on sale for 25% off its regular $500 price. To find the amount of savings, we need to calculate 25% of $500. This is done by multiplying the original price by the percentage discount in decimal form.
The percentage in decimal form is 0.25 (since 25% is 25 per hundred, or 25/100), hence, we multiply 500 by 0.25 to find the savings:
500 × 0.25 = $125.
Therefore, the amount of savings from the original price during the sale is $125.

In the spinner below the large wedges are twice the size of the smaller ones. What is true about the probability of landing on 6 and the probability of landing on 5?
Answer:
A
Step-by-step explanation:
If we take each small section to be "1" unit, we can say the large sections (for "2" and "5") are "2" units each. So in total there will be 8 sections.
Since 5 is "2" sections, we can say:
P(5) = 2/8 = 1/4
And 6 is "1" section, so we can say:
P(6) = 1/8
Definitely, Probability of landing a 6 is HALF that of probability of landing a 5. Also we can see this is the picture.
So, from the answer choices, A is right.

Name two points that are reflections of each other across the x-axis.
Answer:
Original point (1,2) and the image is (1,-2).
Step-by-step explanation:
If a point on the coordinate plane reflects across the x-axis then the x-coordinates of the original point and that of the image point will remain the same and the y-coordinates of the original point and that of the image point will only change their signs.
So, a point having coordinates (a,b) when reflected across the x-axis then the point generated after reflection will have coordinates (a,-b).
This is true for any real values of a and b.
So, for example, if (1,2) is a point reflected across the x-axis will generate an image point with coordinates (1,-2). (Answer)

Answer:
693 sq. m.
Step-by-step explanation:
The figure consists of a triangular prism (Bottom Part) and a Triangular Pyramid (Top Part). We will find the volume of each and add it up to get volume of total figure.
1. Volume of Triangular Prism = Area of Triangular Base * Height
Area of Triangular Base = (1/2)*base*height
Given that the triangle is a right triangle, we find the unknown side by using Pythagorean Theorem, which tells us:
Leg^2 + Another Leg^2 = Hypotenuse^2
8.8^2 + Another Leg^2 = 13.7^2
77.44+ Another Leg^2 = 187.69
Another Leg (unknown side, or the base of the triangle) = Sqrt(187.69-77.44) = 10.5 (this is base of triangle)
So, we have:
Area of Triangular Base = [tex]\frac{1}{2}*10.5*8.8=46.2[/tex]
Thus,
Volume of Triangular Prism = 46.2 * 10(given) = 462 sq.m.
2. Volume of Triangular Pyramid = (1/3) * area of triangular base * height
Here, area of triangular pyramid is 46.2 (already found)
the height of the pyramid is 25 - 10 = 15
SO, we have:
Volume of Triangular Pyramid = [tex]\frac{1}{3}*46.2*15=231[/tex] sq. m.
Now we sum them up and get total volume of the figure:
Total Volume of Figure = 462+ 231 = 693 sq. m.

What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
To find the product of (y+3)(y^2 - 3y + 9), we can use the distributive property of multiplication:
(y+3)(y² - 3y + 9) = y(y² - 3y + 9) + 3(y² - 3y + 9)
Now we can simplify each term:
y(y² - 3y + 9) = y³ - 3y² + 9y
3(y² - 3y + 9) = 3y² - 9y + 27
Adding these two simplified polynomial terms, we get:
(y+3)(y² - 3y + 9) = y³ - 3y² + 9y + 3y² - 9y + 27
Simplifying further, we get:
(y+3)(y² - 3y + 9) = y³ + 27
Hence , the product is A = y³ + 27

At the end of the summer, a store marks down all the outdoor furniture 20%. A family bought 4 chairs that originally cost $102. How much was the cost of the 4 chairs?
Answer:
$81.60
Step-by-step explanation:
A 20% markdown means that the chairs were sold at 80% of the original cost.
Original cost = $102
markdown = 20%
Cost after markdown = original cost* (1-markdown)
Cost after markdown = 102 *(1 - 0.20)
= 102*0.80
= 81.6
Therefore, the 4 chairs were sold at a total cost of $81.60

Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope of fraction 1 over 2 .
Answer:
y + 3 = (1/2)(x -6)
Step-by-step explanation:
When we have the slope m of the line and a point (a,b) which the line passes through, the point-slope form is
y - b = m (x -a)
Since the slope is 1/2 and the line passes through (6, -3), the point-slope equation is
y -(-3) = (1/2)(x -6)
or
y + 3 = (1/2)(x -6)

Estimate. Round to the greatest place value. Circle whether the estimate is greater then or less then the actual product.
Rounding to the greatest place value requires focusing on the digit to the right of the place value you're rounding to. If it's 5 or above, round up, if less, round down. This makes calculations easier by providing an estimated value close to the actual one.
Explanation:In this question, you are asked to estimate a value by rounding to the greatest place value. To do this, you will focus on the digit in the place value you are rounding to and the digit to its right. If the digit is 5 or more, you will round up. If it's less than 5, you will round down. It's called the estimation because it's not an exact value but a value close to the actual one best suited for calculations.
For example, if you have the number 4387 and you want to round it to the greatest place value, which is thousands place, you will look at the hundreds place value which is 8 (greater than 5), so you round up to 5000. Your estimated number, 5000, is greater than the actual product.
The purpose of rounding and estimation is to simplify calculations and analyze systems or data without being bogged down by specificities.

For each sequence,find the first 4 terms and the 10th term
a) n+5
b)2n-1
Answer:
a)6,7,8,9 and 10th term is 15.
b)1,3,5,7 and 10th term is 19.
Step-by-step explanation:
Given a) n+5
b)2n-1
Solution for a) n+5
Taking the value of n is 1 we get the first term of the sequence;
[tex]n+5=1+5=6[/tex]
Similarly taking the value of n 2,3,4 we get;
[tex]2+5=7\\3+5=8\\4+5=9[/tex]
And for 10th term we take the value of n is 10 and get;
[tex]n+5=10+5=15[/tex]
So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.
Solution for b)2n-1
Taking the value of n is 1 we get the first term of the sequence;
[tex]2n-1=2\times1-1=2-1=1[/tex]
Similarly taking the value of n 2,3,4 we get;
[tex]2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7[/tex]
And for 10th term we take the value of n is 10 and get;
[tex]2n-1=2\times10-1=20-1=19[/tex]
So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.
Final answer:
The first 4 terms and the 10th term of sequence (a) n + 5 are 6, 7, 8, 9, and 15, respectively. For sequence (b) 2n - 1, they are 1, 3, 5, 7, and 19, respectively.
Explanation:
For each sequence, we need to find the first 4 terms and the 10th term. The sequences are given by (a) n + 5 and (b) 2n - 1.
Let's start with sequence (a) n + 5. The first 4 terms, where n starts at 1, will be:
1 + 5 = 62 + 5 = 73 + 5 = 84 + 5 = 9The 10th term can be found by substituting n = 10 into the expression, so the 10th term is:
10 + 5 = 15
Moving on to sequence (b) 2n - 1. The first 4 terms are:
2(1) - 1 = 12(2) - 1 = 32(3) - 1 = 52(4) - 1 = 7The 10th term is calculated as:
2(10) - 1 = 19
