Find the 87th term of the arithmetic sequence –19, -13, -7,...
Answer:
87th term is 497
Step-by-step explanation:
first, you have to find the nth term:
figure out the difference between your set of numbers (in our case +6)
that means that is 6n. next, the nth term is basically the 0th term so you have to find the 0th term. all you have to do is do the inverse of 6n (-6n or -6), which gives us -25.
nth term= 6n-25
now replace n with 87.
final step:
87*6 (6n and n=87) and that gives you 522. then, you have to do 522-25, due to the equation. 522-25=497
497 is your 87th term.
Answer:
-535Step-by-step explanation:
[tex]a = -19\\d = T_{2} -T_{1} \\d = -19-(-13)\\d = -19+13\\d = -6\\T_{n}= a+(n-1)d \\\\T_{87} = -19+(87-1)-6\\T_{87} = -19+(86)*-6\\T_{87} = -19-516\\T_{87} = -535[/tex]
Find the value of the unknown in the equation 4p + 2 = 8
a) p = 0
b) p = 2.3
c) p = 1.5
d) p = 4
Answer:
Option C
Step-by-step explanation:
=> 4p + 2 = 8
Subtracting 2 to both sides
=> 4p = 8-2
=> 4p = 6
Dividing both sides by 4
=> p = 1.5
Answer:
The answer is C.
Step-by-step explanation:
First, you have to subtract 2 to both sides :
[tex]4p + 2 = 8[/tex]
[tex]4p + 2 - 2 = 8 - 2[/tex]
[tex]4p = 6[/tex]
Next, you have to divide it by 4 :
[tex]4p = 6[/tex]
[tex]p = 6 \div 4[/tex]
[tex]p = 3 \div 2[/tex]
[tex]p = 1.5[/tex]

Which equation can be used to find one multiple of 16?
16=8= 2
16 = 4= 4
16 x0=0
16 x 2 = 32
Answer:
16x2=32
Step-by-step explanation:
A multiple of 16 is any number divisible by 16. Multiplying 16 by 2 creates a number divisible by 16 and 2, meaning it is divisible by 16.
16x2=32 32/16=2
In right triangle ABC, ∠A is a right angle and sinC=15/17 What is the ratio cosC? Enter your answer as a fraction in simplest form, like this: 42/53
Answer:
8/17
Step-by-step explanation:
Here, we should know that the sine of an angle is the ratio of the opposite to the hypotenuse
So in this case, 15 is the opposite and 17 is the hypotenuse
To find the cos of same angle, it is the ratio of the adjacent to the hypotenuse
We need the adjacent side
We can use Pythagoras’ theorem here
It states that the square of the hypotenuse equals sum of the squares of the two other sides
let’s say the adjacent is f
17^2 = 15^2 + f^2
f^2 = 17^2 -15^2
f^2 = 64
f = √(64)
f = 8
So the Cos C would be adjacent/hypotenuse = 8/17

Answer: 1324.12 sq. cm.
Step-by-step explanation:
A=2πrh+2πr2
A = 2π x 8.2 x 17.5 + 2π x 8.2^2
A = 2π x 143.50 + 2π x 67.24
A= 1324.12
Answer:
SA = 1324.1 cm²
Step-by-step explanation:
Surface Area of Cylinder = [tex]2\pi rh+2\pi r^2[/tex]
Where r = 8.2 cm, h = 17.5 cm
=> SA = [tex]2(3.14)(8.2)(17.5)+2(3.14)(8.2)^2[/tex]
=> SA = [tex]901.6+2(3.14)(67.24)[/tex]
=> SA = 901.6 + 422.5
=> SA = 1324.1 cm²

.- Calcule el interés producido por un capital de 4 500 dólares al 5% de interés simple anual en 8 meses.
Answer: $150
Step-by-step explanation:
Hi, the question says:
Calculate the simple interest produced by $4500 at 5% simple annual interest in 8 months.
To answer this question we have to apply the simple interest formula:
I = p x r x t
Where:
I = interest
P = Principal Amount
r = Interest Rate (decimal form)
t = years
Since 1 year = 12 months;
For 8 months:
8/12 = 2/3 years
Replacing with the values given
I = 4500 x (5/100) x 2/3
I = $150

Reflect triangle a in the x axis to give triangle b. Then rotate your triangle b 90 degrees clockwise around the origin to give triangle c. Describe fully the single transformation that maps triangle a onto c
Answer:
The single transformation that maps a onto c is the reflection of the triangle a about the line y = -x
Step-by-step explanation:
To answer the question, we note that the result of reflection of a point (x, y) across the x axis is given as follows;
Coordinates before reflection = (x, y), Coordinates after reflection = (x, -y)
Also, when we rotate a point, (x, y), 90° clockwise, we have;
Image point before 90° clockwise rotation = (x, y), Image point after 90° clockwise rotation = (y, -x)
Therefore, the rotation of the point (x, -y), 90° clockwise will give
Image point before 90° clockwise rotation = (x, -y), Image point after 90° clockwise rotation = (-y, -x)
Which gives the combined transformation as (x, y) → (-y, -x) which is the rule equivalent to reflection about the line y = -x.

And we have our answer.
what is the shape graphed by the function r = 1+ sin theta
Answer: Is known as a "heart" shape.
Step-by-step explanation:
r = 1 + sin(θ)
Let's do it without a graph, let's use only math and logic:
remember that θ is measured from the x-axis
when θ = 0, we have r = 1 (so we have a radius of 1 over the x-axis)
when θ = pi/2, we have r = 1 + sin(pi/2) = 2
when θ = pi, we have r = 1 + sin(pi) = 1
when θ = 3*pi/2, we have r = 1 + sin(3*pi/2) = 0
First, we have symetry around the y-axis,
now, notice that the value of x in θ = 0, θ = pi and θ = 3*pi/2 is the same. so this is not a circle, this is actually a circle where the bottom part is flatted.
But not actually flat, because between θ = pi and θ = 2pi we are in the negative y-axis, so in this region we have two small bumps that connect in the point (0, 0)
This is a kinda "heart" shape.

Answer:
[tex]m=27[/tex]
Step-by-step explanation:
When something is directly proportional, it means that: [tex]a=kb[/tex], where [tex]k[/tex] is some constant (number).
We are given that [tex]m[/tex] is directly proportional to [tex]n^2[/tex], and [tex]m=75[/tex] when [tex]n=5[/tex].
So, we have...
[tex]a=kb[/tex]
[tex]m=kn^2[/tex]
[tex]75=k(5)^2[/tex]
[tex]75=25k[/tex]
[tex]k=3[/tex]
So the full equation is:
[tex]m=3n^2[/tex]
Now, to find the answer when [tex]n=3[/tex], simply put 3 into the equation.
Which gives:
[tex]m=3(3)^2[/tex] [tex]m=9(3)[/tex] [tex]m=27[/tex]
Final answer: m=27.
Find the area of the circle use 3.14 for
Answer:
530.66 cm²
Step-by-step explanation:
Area of a circle is 3.14 × radius²
3.14 × 13²
3.14 × 169
=530.66
The area of the circle is 530.66 cm².
Answer:
The answer is (approximately) [tex]530.66 cm^2[/tex]
Step-by-step explanation:
We are given the radius ([tex]13cm[/tex]).
Use the formula for the area of a circle: [tex]\pi r^2[/tex] (using [tex]3.14[/tex] for [tex]\pi[/tex])
Thus...
[tex](3.14)(13)^2[/tex]
We equals around 530.66.
You drive an average of 750 miles per week in a car that gets 28 miles per gallon. With gasoline prices at $3.40 per gallon, what would be the difference in total weekly cost of gasoline if you start driving an SUV that gets 20 miles per gallon?
Answer:
$36.41/week
Step-by-step explanation:
Divide 750 miles/wk by 28 MPG -> = 26.79 gallons/week (I rounded.)
Divide 750 miles/wk by 20 MPG -> = 37.50 gallons/week
Car -> 26.79 gallons x $3.40 = $91.09
SUV -> 37.50 gallons x $3.40 = $127.50
$127.50 - $91.09 = Difference of $36.41/week
The difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
You drive an average of 750 miles per week in a car that gets 28 miles per gallon. With gasoline prices at $3.40 per gallon.
For the first car:
Total number of miles = 750 miles
The gasoline prices at $3.40 per gallon
The car that gets 28 miles per gallon
Number of gallons used = 750/28 = 26.785
The total price of the gallon used = 26.785x3.40 = $91.07
For the SUV car:
Total number of miles = 750 miles
The gasoline prices at $3.40 per gallon
The car that gets 20 miles per gallon
Number of gallons used = 750/20 = 37.5
The total price of the gallon used = 37.5x3.40 = $127.5
The difference in total weekly cost of gasoline = 127.5 - 91.07 = $36.43
Thus, the difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.
