Given the sequence {-1, 3, 7, 11, ...}, find a25
here,
a1=-1
a2=-1+4 =3
a3= 3+4=7
a4=7+4=11
using the general formula for nth term of an ap
[tex]an = - 1 + (n - 1)d \\ here \: a = - 1 \: and \: d = 4 \\ \\ an = - 1(n - 1)(4) = - 1 + 4 - 4 \\ 4n - 5 \\ \\ hence \: a25 = \\ 4(25) - 5 = 100 - 5 = 95[/tex]
Answer= a25 = 95
A circle is centered at the point (-7, -1) and passes through the point (8, 7).
The radius of the circle is____ units. The point (-15,___ ) lies on this circle..
I will give Brainliest
Answer:
Step-by-step explanation:
radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit
Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2
= (-15+7)^2 + (y+1)^2 = 17^2
=14
(-15, 14) lies on this circle

Find the missing length of the triangle.
Answer:
12 =c
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
7.2 ^2 + 9.6 ^2 = c^2
51.84+92.16= c^2
144 = c^2
Taking the square root of each side
sqrt(144) = sqrt(c^2)
12 =c
Answer:
Let's find the hypotenuse.
7.2^2 + 9.6^2
51.84 + 92.16 = 144
√144(square root of 144) = 12, c = 12

Solve for R.
3/4r-3 1/4=49/16
Answer:
101/12
Step-by-step explanation:
3/4r-3 1/4=49/16
3 1/4=13/4
3/4r-13/4=49/16
3/4r=49/16+13/4
3/4r=49/16+52/16
3/4r=101/16
r=(101/16)/(3/4)
r=(101/16)(4/3)
r=101/12

Using the quadratic formula to solve 2x^2 = 4x - 7, what are the values of x?
Answer:
Is C.
Step-by-step explanation:
Consider,
2x² = 4x - 7
2x² - 4x + 7 = 0
using Quadratic Formula
Therefore, Option C is correct.

Solve for x. Thank you
Given:
A figure of a right angle triangle.
To find:
The value of x.
Solution:
First, label the vertices figure as shown below.
In triangle ABC and DBA,
[tex]\angle BAC\cong \angle BDA[/tex] (Right triangles)
[tex]\angle ABC\cong \angle DBA[/tex] (Common angle)
[tex]\triangle ABC\sim \triangle DBA[/tex] (AA property of similarity)
We know that the corresponding sides of similar triangles are proportional.
[tex]\dfrac{BC}{BA}=\dfrac{AB}{DB}[/tex]
Substituting the given values from the below figure, we get
[tex]\dfrac{x}{8\sqrt{3}}=\dfrac{8\sqrt{3}}{12}[/tex]
[tex]x=\dfrac{8\sqrt{3}}{12}\times 8\sqrt{3}[/tex]
[tex]x=\dfrac{192}{12}[/tex]
[tex]x=16[/tex]
Therefore, the value of x is 16 and correct option is B.
Consider the function.
f(x) = x2 + 3
Which answer pairs a possible domain restriction that if placed upon f(x) would impact f–1(x) as shown?
Answer:
b
Step-by-step explanation:
edge 2021
The solution is:
B. f(x) domain: x ≥ 1
f–1(x) range: y ≥ 1
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
Here, we have,
Because the two functions are inverse to each other, so we all know that the domain of f(x) will be the range of f^-1(x) and the range of f(x) will be the domain of f^-1(x)
As can be seen from the attached photo,
f(x) extends to the right of x=1, so its domain is x ≥ 1.
<=> f^-1(x) range is y≥ 1.
Therefore, we choose answer B

△ABC is reflected across the y-axis on a coordinate plane, resulting in △A′B′C′. If the measure of ∠A is 50 degrees, what is the measure of ∠A′?
Answer:
Reflections across the line y = x
A reflection across the line y = x switches the x and y-coordinates of all the points in a figure such that (x, y) becomes (y, x). Triangle ABC is reflected across the line y = x to form triangle DEF. Triangle ABC has vertices A (-2, 2), B (-6, 5) and C (-3, 6).
Janine is running at 10 kilometers per hour. How long will it take Janine to travel 15 kilometers?
Step-by-step explanation:
janine is running 10 kilometer per 60 minutes
means janine runs 1 km in
=60/10
=6
since,Janine runs 1 km per 6 minutes
how much time does janine takes to run 15 km
=15 ×6
=90
Therefore Janine takes 90 minutes to run 15 km ie1 hour 30 minutes

Answer: the slope of green line = [tex]-\frac37[/tex]
Step-by-step explanation:
We know that,
If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.
Given: The red line and the green line are parallel.
The slope of red line = [tex]-\frac37[/tex]
Then, the slope of green line = [tex]-\frac37[/tex] [Slopes of two parallel lines are equal]
Hence, the slope of green line = [tex]-\frac37[/tex]
