Find the equation of a parabola whose vertex is at (−1, 7), whose axis of symmetry is
x = −1, and whose y-intercept is (0, 10). Write your answer in vertex form.
Answer:
Step-by-step explanation:
The axis of symmetry is vertical, so the parabola is vertical.
Vertex-form equation for a vertical parabola with vertex (h,k):
y = a(x-h)² + k
axis of symmetry: x = h
Apply your data and solve for h, k, and a.
vertex (-1,7)
h = -1
k = 7
y = a(x+1)² + 7
(0,10) is a point on the parabola
10 = a(0+1)² + 7
a = 3
The equation becomes
y = 3(x+1)² + 7

Step-by-step explanation:
Given
The attached figure
Required
Find x
To solve for x, we make use of the following equivalent ratio
[tex]x :3.5 = 5 : 7[/tex]
Express as fractions
[tex]\frac{x}{3.5} = \frac{5}{7}[/tex]
Make x the subject
[tex]x= \frac{5}{7}*3.5[/tex]

Find the following for the function f(x)= 3x2 + 4x - 3.
(a) f(0)
(e) -f(x)
(b) f(3)
(f) f(x + 2)
(c) f(-3)
(g) f(3x)
(d) f(-x)
(h) f(x + h)
Step-by-step explanation:
a. -3
e. -3x^2 -4x +3
b 27+12-3= 36
f. 3(x+2)^2 + 4(x+2) -3
c. 27-12-3= 12
g. 3(3x)^2 + 4(3x) -3
d. 3x^2 -4x -3
h. 3(x+h)^2 + 4(x+h) -3
The all values of the function f(x)= 3x² + 4x - 3 are f(0) = -3 ,-f(x) = -3x² -4x +3, f(3) = 27+12-3= 36 ,f(x + 2)= 3(x+2)² + 4(x+2) -3 ,f(-3)= 27-12-3= 12,f(3x) = 3(3x)² + 4(3x) -3,f(-x) = 3x² -4x -3,f(x + h) = 3(x+h)² + 4(x+h) -3.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
a) f(0) = -3
(e) -f(x) = -3x² -4x +3
(b) f(3) = 27+12-3= 36
(f) f(x + 2)= 3(x+2)² + 4(x+2) -3
(c) f(-3)= 27-12-3= 12
(g) f(3x) = 3(3x)² + 4(3x) -3
(d) f(-x) = 3x² -4x -3
(h) f(x + h) = 3(x+h)² + 4(x+h) -3

The Bluejay Apartments is a new development and is in the process of structuring its lease agreements. The company would like to set the damage deposits high enough that tenants will keep the apartments in good condition. The company is actually more concerned about damage than about tenants not paying their rent.
a) Discuss the tax effects of the following alternatives:
i. $1,000 damage deposit with no rent prepayment�
ii. $500 damage deposit and $500 rent for the final month of the lease
iii. $1,000 rent for the final two months of the lease and no damage deposit
b) Which option do you recommend
Answer:
The Bluejay Apartments
1. Tax Effects of the following Alternatives:
i. $1,000 damage deposit with no rent prepayment
No tax will be paid by The Bluejay Apartments until the deposit will no longer be refunded.
ii. $500 damage deposit and $500 rent for the final month of the lease
Tax will be paid on the rental income of $500 and on the $500 if it will no longer be refunded. If it is taken as part of the rent income for a month, then tax will be paid on a total income of $1,000.
iii. $1,000 rent for the final two months of the lease and no damage deposit
Tax will be paid on the rent income of $1,000.
b) From a tax point of view, option i is recommended.
Step-by-step explanation:
According to the IRS, a security or damage deposit is not taxable when it is received by the landlord. It becomes taxable income when the landlord is no longer obligated to return it to the tenant. The reason a damage deposit is not taxed is that it is recorded as an asset and not an expense or income.

3) What is an equation for the line that passes through the coordinates (-1.2) and (7,6) ?
Answer:
[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]
Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.
[tex]\frac{6-2}{7- (-1)}=\frac{4}{8}=\frac{1}{2}[/tex]
So now we have the equation [tex]y=\frac{1}{2} x+b[/tex], and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation
[tex]2=\frac{1}{2}(-1)+b[/tex]
Rearrange the equation so it equals b
[tex]\frac{5}{2}=b[/tex]
Put it together and that's the final equation!
[tex]y=\frac{1}{2} x+\frac{5}{2}[/tex]

Three even numbers sum up to 108. The smaller is half the larger and the middle number is 3/4 the larger. What
are the three numbers
Answer:
Step-by-step explanation:
Represent the three even numbers as 2x, 2y, 2z, where x,y,z are integers.
2x+2y+2z = 108
x+y+z = 54
Let x≤y≤z
x = z/2
y = ¾z
z/2 + 3z/4 + z = 54
2z/4 + 3z/4 + 4z/4 = 54
2z + 3z + 4z = 216
9z = 216
z = 24
x = z/2 = 12
y = ¾z = 18
The numbers are 24, 36, 48

VERY QUICK HELP!!!! A toy pyramid has the dimensions shown below. The base of the pyramid is an equilateral triangle. What is the surface area of this pyramid?
Answer: 102cm²
Step-by-step explanation:
Area of base = 6 × 7 ÷ 2 = 21
Area of lateral face = 6 × 9 ÷ 2 = 27
Since all of the sides of the base are equal, we can multiply the area of 1 lateral face by 3 to get the area of all the lateral faces.
27 × 3 = 81.
Now we add up the area of the base and the lateral faces.
21 + 81 = 102cm²

Triangle DEF with vertices D(2, 6), E(5, 6)and F(5, 1). Write the coordinates of triangle D’E’F’ after a
reflection over the y-axis.
Answer:
The coordinates of triangle after reflection over y-axis
D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)
Step-by-step explanation:
Explanation:-
Given that DEF with vertices D(2,6), E(5,6), and F(5,1)
Given that the triangle DEF reflection over the 'y' - axis then transformed into
( x,y) → (-x,y)
Now,
D(2,6) → D¹( -2 ,6)
E(5,6)→ E¹( -5 ,6)
F(5,1)→ F¹ (-5,1)
Final answer:-
The coordinates of triangle after reflection over y-axis
D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)

Sum triangle is 180 degree
Let f(x) = tan(x) - 2/x. Let g(x) = x^2 + 8. What is f(x)*g(y)?
Answer:
[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=tan(x)-\frac{2}{x}[/tex]
[tex]g(x)=x^2+8[/tex]
We have to find [tex]f(x)\times g(y)[/tex]
To find the value of [tex]f(x)\times g(y)[/tex] we will multiply f(x) by g(y)
[tex]g(y)=y^2+8[/tex]
Now,
[tex]f(x)\times g(y)=(tanx-\frac{2}{x})(y^2+8)[/tex]
[tex]f(x)\times g(y)=tan(x)(y^2+8)-\frac{2}{x}(y^2+8)[/tex]
[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]
Hence,
[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]
