Write the standard equation of the ellipse with center at the origin, and vertices at (-4,0), (4,0), (0, -3), and (0,3).
9514 1404 393
Answer:
(a) x^2/16 +y^2/9 = 1
Step-by-step explanation:
The form for the equation of an ellipse centered at the origin is ...
(x/(semi-x-axis))^2 +(y/(semi-y-axis))^2 = 1
The vertex values tell you the semi-x-axis is 4 units, and the semi-y-axis is 3 units. Then you have ...
(x/4)^2 +(y/3)^2 = 1
x^2/16 +y^2/9 = 1
__
In case you don't remember that form, you can try any of the points in the equations. The equation that works will quickly become apparent.
Answer: actually it is
x^2/16 +y^2/7 = 1
Step-by-step explanation:
the answer above is right for the X part, for the Y part it is 7, not 9!

Given:
The diagram of a figure with sides 14 ft, 30 ft, 21 ft and 18 ft.
To find:
The area of the figure.
Solution:
From the given figure it is clear that if we cut a corner of a rectangle, then we get the same figure.
The sides of a the rectangle are 30 ft and 21 ft.
The height of the triangular part is (30 ft - 18 ft) and the base is (21 ft - 14 ft).
So, the height of the triangular part is 12 ft and the base is 7 ft.
The area of the rectangle is:
[tex]A_1=length\times width[/tex]
[tex]A_1=30\times 21[/tex]
[tex]A_1=630[/tex]
The area of the triangular part is:
[tex]A_2=\dfrac{1}{2}\times base \times height[/tex]
[tex]A_2=\dfrac{1}{2}\times 12 \times 7[/tex]
[tex]A_2=6 \times 7[/tex]
[tex]A_2=42[/tex]
Now, the area of the given figure is:
[tex]A=A_1-A_2[/tex]
[tex]A=630-42[/tex]
[tex]A=588[/tex]
Therefore, the area of the given figure is 588 sq. ft.

Answer:
9.32
10.116
Step-by-step explanation:
each corner is a right corner so were going to subtract 58 from 90 because all right corners are 90 degrees
90-58=32 answer A 32
after that we know that all triangles have to equal 180 so now we subtract
180-58=122 122-58=64
we subtract 58 two times because we have 2 of the same angles
next we know that the smaller angle is 32 so now we subtract again
180-32=148 148-32=116 so y is 116
Question 10 of 10
If a sample mean is 37, which of the following is most likely the range of
possible values that best describes an estimate for the population mean?
O A. (28,36)
B. (32, 42)
C. (34, 42)
D. (30,38)
If a sample mean is 37, (32, 42) is most likely the range of possible values that best describes an estimate for the population mean. The correct option is C.
What is mean?In math, a mean is the average of a data set, which is calculated by adding all of the numbers together and then dividing the sum of the numbers by the number of numbers.
Assuming a moderate sample size (e.g., n = 30) and a typical population standard deviation (e.g., σ = 10), the SEM can be estimated to be approximately 2.
Using this estimate, the range of possible values for the population mean can be calculated as:
37 - x = 33
37 + 2 * 2 = 41
Therefore, the most likely range of possible values for the population mean is option C.

-Chetan K
Here's the solution,
the ratio of length and breadth of the house is :
=》16 : 12
=》4 : 3
so, let's take the actual breadth be ' x '
we know,
=》32 : x = 4 : 3
because it's the ratio of length and breadth of the house
so,
[tex] \dfrac{32}{x} = \dfrac{4}{3} [/tex]
=》
[tex]x = 32 \times \dfrac{3}{4} [/tex]
=》
[tex]x = 24[/tex]
hence, the actual breadth of the house is 24 feet
A manufacturer of screened sweatshirts includes a shipping charge of $5.99 on all online orders. Customers also pay 2.5% tax on their purchases. There is a linear relationship between c, the cost of the items purchased, and t, the total cost including shipping and tax. Select each statement that correctly represents the relationship between c and t. Mark all that apply. *
Answer:
t = 1.025c + 5.99
Step-by-step explanation:
Recall : general for of a linear equation is given by :
y = mx + c
Given the following :
Item cost = c
Shipping charge = $5.99
Tax on purchases = 2.5%
Total cost, t
t = c + tax + shipping cost
Tax on purchase : 2.5% * item cost ; 0.025c
Shipping = $5.99
Hence,
Total cost, t = c + 0.025c + 5.99
t = 1.025c + 5.99

which i wwill round to
16755.63
The amount in the retirement account is A = $ 16,755.63
What is Compound Interest?Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
Let the compound interest amount be represented as A
Now , the interest rate r = 6.05 %
The number of times the interest is applied = weekly
The principal amount P = $ 5,000
Now , the number of years = 20 years
And , A = P ( 1 + r/n )ⁿᵇ
On simplifying , we get
A = 5,000.00(1 + 0.0605/52)⁵²ˣ²⁰
A = 5,000.00(1 + 0.0011634615384615)¹⁰⁴⁰
A = $ 16,755.63
Hence , the amount is A = $ 16,755.63
