Answer 1
Answer:
a₂₅ = - 367
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 22 - (- 7) = - 37 - (- 22) = - 15
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 15 , then
a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

Find the IQR: (find the median, then find the median of the first group and then the next group. Now subtract big median minus the small median.) 20, 17, 16, 3, 7, 45
Answers
Answer:
13
Step-by-step explanation:
The IQR = Interquartile Range is the difference between the first and third quartile
Rearranged data set:
3, 7, 16, 17, 20, 45
Step 1
We find the first quartile = Q1
= 1/4(n + 1)th number
n = 6
= 1/4(6 + 1)th
= 1/4(7)th
= 1 3/4th number
This = 7
Step 2
We find the third quartile = Q3
= 3/4(n + 1)th number
n = 6
= 3/4(6 + 1)th
= 3/4(7)th
= 21/4th number
= 5 1/4 th number
This = 20
Step 3
IQR = Q3 - Q1
= 20 - 7
= 13

it appears that there are 7 cubes, so divide the overall volume by the seven cubes, making the volume of each one would 8. Volume is length times with times height so you would find the cube root of eight which is two. This means that each side length is 2 so you would find the area of each side and add them all together. This adds up to equal 120.
Hope this helped!!
the answer is C.

GEOMETRY HELP PLEASE! Thank you. A quadrilateral has two angles that measure 80° and 150°. The other two angles are in a ratio of 2:11. What are the measures of those two angles?
Answers
Answer:
23.6 and 106.4
Step-by-step explanation:
answer: 20° and 110°
explanation: quadrilaterals must add up to 360° so in order to find out the total of the other two angles, subtract both of the given angles from the total 360.
360 - 80 - 150 = 130
you then take the ratio and add the two numbers
2 + 11 = 13
next you would divide the total of the two unknown angles by this number.
130/13 = 10
lastly, to get each angle, you would multiply each side of the original ratio
2 x 10 = 20
11 x 10 = 110
to double check, you would all four angles to make sure it equals 360
150 + 80 + 20 + 110 = 360

hi! i believe the answer is a, because if b (in this case 0.2) is less than 1 and greater than 0 its exponential decay!! good luck with the rest of your hw and i hope this helps
Answer:
A
Step-by-step explanation:
Exponential growth is when numbers increase rapidly in an exponential fashion so for every x-value on a graph there is a larger y-value. Decay is when numbers decrease rapidly in an exponential fashion so for every x-value on a graph there is a smaller y-value. So here the one that fits the description is A.

I really need help with this one.
Answers
Answer:
CD = 48
Step-by-step explanation:
Find the value of x using the two equations
9x - 15 = 7x - 1
9(7) - 15 = 7(7) - 1
63 - 15 = 49 - 1
48 = 48
Answer: x = 7
Then get the result of both equations
CD = 48
The length of CD is 48 units.
What is Isosceles Triangle?
Isosceles triangles are those triangles which has the length of two sides or angles are equal to each other.
Given triangle ABC is an isosceles triangle since the length of sides AB and BC are given to be equal.
BD is the altitude of the triangle from the vertex B.
We know that, altitude of an isosceles triangle from the non equal angle bisect the opposite side, which is base.
So, AC is bisected at D.
AD = CD
9x - 15 = 7x - 1
Solving,
9x - 7x = -1 + 15
2x = 14
x = 7
Length of CD = 7x - 1 = 49 - 1 = 48
Hence 48 units is the length of CD.

Find an equation of the line perpendicular to Y equals 3X -3 and passes through the point -3 and -1
Answers
Answer:
y = - [tex]\frac{1}{3}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 3 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = 1 + c ⇒ c = - 1 - 1 = - 2
y = - [tex]\frac{1}{3}[/tex] x - 2 ← equation of perpendicular line
