Answer:
x minus 3
is the formula to this question
Answer:
Step-by-step explanation:
Nth term of the given A.P is
here a=25 and d=-3
so Tn=a+(n-1) d
=25+(n-1)-3
=25-3n+3
=28-3n
THIS IS THE Nth TERM
Fill in the missing term on each line. Simplify any fractions.
2d + 10 = 10
2d =
Subtract 10 from both sides
d =
Divide both sides by 2
the answer is,......
d = 0

#6 Find x to show that Quadrilateral ABCD is a parallelogram.
Answer:
x = 5
Step-by-step explanation:
Diagonals of a parallelogram bisect each other. Based on this knowledge, to show that the quadrilateral is a parallelogram, therefore:
3x - 4 = x + 6
Solve for x
Collect like terms
3x - x = 4 + 6
2x = 10
Divide both sides by 2
x = 5

Find g(x), where g(x) is the translation 7 units right of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers.
Answer:
[tex]g(x) =1(x + 7)^2 + 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
Required
Determine g(x) where g(x) is a translation of f(x), 7 units to the right
When a point is translated to the right, the resulting point is:
[tex]x -> x + b[/tex]
Where b is the number of units to the right.
In this case:
[tex]b = 7[/tex]
So, we have:
[tex]g(x) = f(x +7)[/tex]
Solving f(x+7)
Substitute x + 7 for x in [tex]f(x) = x^2[/tex]
[tex]f(x + 7) = (x+7)^2[/tex]
So, we have:
[tex]g(x) = (x+7)^2[/tex]
To write in the form of [tex]a(x - h)^2 + k[/tex], we have:
[tex]g(x) =1(x + 7)^2 + 0[/tex]
In the right triangle shown m angle A =45° and AB=12 how long is BC?
Answer: there u go this the correct answer if your on khan academy.
From the given right angle triangle, the length of side BC will be equal to 6√2.
What is a right angle triangle?Any triangle that has one 90º angle has a right angle. Right triangles are those with an angle of 90 degrees, or "right angles," and are therefore those with this angle. The Pythagorean rule can be used to clarify the relationship between both the triangle's different sides.
As per the data provided in the question,
If one of the angles in a right triangle is 45 degrees, therefore the complimentary angle must also be 45 degrees.
Then,
m∠B = 45°
From the triangle ABC.
Cos B = BC/AB
As we know, the value of cos at 45° = √2/2
AB = 12
BC = cos (B) (AB)
BC = (√2/2) × 12 = 6√2 units.

A stadium had a total of 19,000 seats. Of these seats 5,500 are field seats, and the rest are grandstand seats. Complete an equation that could be used to find s, the number of grandstand seats
Answer: The equation to find Number of grand seats, s are either of the following
x+ s= Total seats
x+s= 19,000
5000+s= 19,000
Number of grand seats, s= 14,000
Step-by-step explanation:
Step 1
A stadium had a total of 19,000 seats.
Given that field seats=5,500
And the rest which are grandstand seats=?
Let field seats be represented as x and grand seats be represented as s
such that the total number of seats can be expressed as
x+ s = Total seats
x+ s= 19,000-------- Equation.
5000+s= 19,000
Step 2
Such that given field seats, x= 5000, Number of grand seats will now be
x + s= 19,000
5000 + s= 19,000
s= 19,000-5000
=14,000 seats

The 10th, 4th and 1st term of an A.P are three consecutive find the common ratio of the G.P and the sum of the 6th term, taking the 1st term to be 4
Answer:
Common ratio=1/2
Sum of first 6 terms of an A.P=31.5
Step-by-step explanation:
Let a be the first term and d be the common difference of an A.P
a=4
nth term of an A.P
[tex]a_n=a+(n-1)d[/tex]
Using the formula
[tex]a_4=a+3d=4+3d[/tex]
[tex]a_{10}=a+9d=4+9d[/tex]
According to question
We know that
For G.P
[tex]\frac{a_n}{a_{n-1}}=r[/tex]=Common ratio
[tex]r=\frac{4+3d}{4+9d}=\frac{4}{4+3d}[/tex]
[tex]\frac{4+3d}{4+9d}=\frac{4}{4+3d}[/tex]
[tex](4+3d)^2=\frac{4}{4+3d}[/tex]
[tex]16+9d^2+24d=16+36d[/tex]
[tex]9d^2+24d-36d-16+16=0[/tex]
[tex]9d^2-12d=0[/tex]
[tex]3d(3d-4)=0[/tex]
[tex]d=0, d=4/3[/tex]
Substitute the value of d
When d=0
[tex]r=\frac{4}{4+3d}=\frac{4}{4+0}=1[/tex]
When d=4/3
[tex]r=\frac{4}{4+3\times \frac{4}{3}}=\frac{1}{2}[/tex]
But we reject d=0 because if we take d=0 then the terms are not consecutive terms of G.P
Sum of n terms of an A.P
[tex]S_n=\frac{n}{2}(2a+(n-1)d)[/tex]
Using the formula
Substitute n=6 and d=1/2
[tex]S_6=\frac{6}{2}(2(4)+5\times \frac{1}{2})[/tex]
[tex]S_6=31.5[/tex]

Let us take a look, at these fractions in decimal forms.
1/7 = 0.14
2/7 = 0.28
3/7 = 0.42
4/7 = 0.57
5/7 = 0.71
From, these we can see that the value of the numbers keep increasing. So, the sequence above is increasing.

The height of Moyo and that of
Adamu differs by 9. The difference of the squares of their height is 120.
Find their heights.
Answer:
The height of Moyo is
[tex]\frac{67}{6}[/tex]
The height of Adamu is
[tex]\frac{13}{6}[/tex]
Step-by-step explanation:
Equations
To solve the problem, we assign the variable:
x = height of Moyo
Since Moyo is 9 units taller than Adamu:
x - 9 = height of Adamu
The difference of the squares of their heights is 120, thus:
[tex]x^2-(x - 9)^2=120[/tex]
Operating:
[tex]x^2-(x^2-18x+81)=120[/tex]
[tex]x^2-x^2+18x-81=120[/tex]
Simplifying:
[tex]18x-81=120[/tex]
Adding 81:
[tex]18x=120+81=201[/tex]
Dividing by 18:
[tex]x=\frac{201}{18}=\frac{67}{6}[/tex]
The height of Moyo is
[tex]\frac{67}{6}[/tex]
The height of Adamu is
[tex]\frac{67}{6}-9=\frac{13}{6}[/tex]
Lashonda rented a truck for one day. There was a base fee of $9.75 , and there was an additional charge of 9 cents for each mile driven. The total cost, C (in dollars), for driving X miles is given by the following function.
C (X) =0.09x +9.75
What is the total rental cost if Lashonda drove 30 miles?
need major help pleaseee this is functions
Answer:
$12.45
Step-by-step explanation:
To find the rental cost, plug in 30 as x
c(x) = 0.09x + 9.75
c(30) = 0.09(30) + 9.75
c(30) = 12.45
