Answers

Answer 1

A rational number is part of a whole expressed as a fraction, decimal or a percentage. ... It is a numberthat cannot be written as a ratio of two integers (or cannot be expressed as a fraction). For example, the square root of 2 is an irrational number because it cannot be written as a ratio of two integers.

Enter a recursive rule for the geometric sequence. 10, −80, 640, −5120, ...

a(1)=
a(n)=

Answers

The recursive formula would be:
[tex]a_1=10 \\a_{n}=a_{n-1} \times (-8)[/tex]

This is because the first term, a₁, is 10. A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio. The common ratio, or the number that each term is multiplied by, is -8.

Answer:

The value is:

a(1)=10 and a(n)=(-8)×a(n-1)

Step-by-step explanation:

We are given a sequence as:

10, -80 , 640 , -5120 ,.........

since by looking at the sequence we could see that it is a geometric progression (G.P.) with common ratio -8.

Also a(1) denotes the first term of the sequence and a(n) denotes the nth term of the sequence.

a(1)=10

Also a(n)=(-8)×a(n-1)

since a(1)=10

a(2)=(-8)×10=-80

a(3)=(-8)×(-80)=640

a(4)=(-8)×640=-5120

and so on.

Hence the answer is:

a(1)=10 and a(n)=(-8)×a(n-1)

there was a warning of volcano eruption in Kilauea in Hawaii. from September 7th to September 8th 2014, the flow advanced about 3/8 kilometers towards the edge of highway 130. the distance (in kilimeters) between the edge of the lava flow and the highway 130 can be given by the function f(t)=6-3/8t where t is the number of days since September 9, 2014. what is the input variables? What are the units of the input variable?

Answers

Answer: The input variable is the number of days since September 9th.. The unit for the input variable is single days.

When you are given an equation, there is an input and an output. In this case, you put in the number of days and the output is the distance between the lava and the road.

If you make a chart of the inputs and outputs, you will see that the lava is getting closer to the road.

Sarah is blowing up spherical balloons for her brother's birthday party. One of the balloons has a radius of 3 inches. Round to the nearest tenth.

Suppose Sarah can inflate the balloon at a rate of 200 cubic inches per minute. How long will it take her to inflate the balloon?

Answers

we know that
[volume of a sphere]=(4/3)*pi*r³
for r= 3 in
calculate the volume of one balloon
balloons=(4/3)*pi*r³-------> (4/3)*pi*3³----------> 113.04 in³

if the rate is 200 in³ --------------------> 1 minute
113.04 in³------------------------> X
X=113.04/200------------> 0.5652

the answer is 0.6 minutes

Final answer:

Sarah will take approximately 0.6 minutes or 34 seconds to inflate a spherical balloon with a radius of 3 inches at a rate of 200 cubic inches per minute, after calculating the volume of the balloon and dividing by the rate.

Explanation:

How long will it take Sarah to inflate a spherical balloon with a radius of 3 inches at a rate of 200 cubic inches per minute?

To solve this problem, we first need to calculate the volume of the spherical balloon using the formula for the volume of a sphere, which is [tex]V = $\frac{4}{3}$\pi r^3[/tex], where r is the radius of the sphere. In this case, the radius is 3 inches. Plugging the values into the formula, we get:

[tex]V = $\frac{4}{3}$\pi (3)^3 = $\frac{4}{3}$\pi (27) = 36\pi cubic inches[/tex]

Now, given that Sarah can inflate the balloon at a rate of 200 cubic inches per minute, we can calculate the time it takes to inflate the balloon by dividing the total volume by the rate:

[tex]Time = $\frac{Volume}{Rate}$ = $\frac{36\pi}{200}$ minutes[/tex]

Using the approximation $\pi = 3.14$, this results in:

[tex]Time = $\frac{36 \times 3.14}{200}$ = $\frac{113.04}{200}$ ≈ 0.565 minutes[/tex] or about 33.9 seconds, rounded to the nearest tenth.

Therefore, it will take Sarah approximately 0.6 minutes or 34 seconds to inflate the balloon.

jamal purchased a boat for 7/10 of the asking price of $18,950. He had to pay 6.5% sales tax. What was the amount of Jamal's bill?

Answers

Hello,

Since Jamal is only paying for 7/10 of the asking price, we can multiply it by 0.7.

0.7 x 18950 = 13265

Now, we have to add on the tax, so we should multiply the new amount by 1.065.

13265 x 1.065 = 14127.23

Jamal's bill will be $14,127.23

Jasmine has a piece of ceramic tile that is shaped as a parallelogram. What is the area of this parallelogram?
96 in²
288 in²
352 in²
384 in²

Answers

⓵ To calculate the area of a parallelogram, the formula is base times height, just like the formula for the area of a rectangle! Why? Because if you look closely, every parallelogram can be made into a rectangle just by moving one of the triangle parts of it.

⓶ Now that we know that the formula to calculate the area of a parallelogram is :
A = b × h

You need to find the numbers to replace the base and the height in the formula!

We already know that the height is : 12 in.

So we are left with a formula looking like this :

A = b × 12 in.

⓷ Now we need to find the base! To do so, you need to add the height of the rectangle (which is 8 in.) to the height of one of the triangle (which is 16 in.) :

8 in. + 16 in. = b

↓

8 in. + 16 in. = 24 in.

↓

24 in. = b

So we are left with a formula looking like this:

A = 24 in. × 12 in.

⓸ All there’s left to do now, is calculate the area of the parallelogram using the formula :

A = 24 in. × 12 in.

↓

24 in. × 12 in. = 288 in.²

↓

A = 288 in.²

So your final answer is : the area of this parallelogram is ↠ 288 in.²

I really hope this helped, if there’s anything just let me know! ☻

For the total length of the five rods in terms of a is L = 15a.

The formula for the Total Length of Five Rods

Certainly! To find a formula for the total length (L) of the five rods in terms of a, let's denote the lengths of the rods as a, 2a, 3a, 4a, and 5a (since there are five rods, each consecutive rod has a length that is one unit greater than the previous rod). So, the lengths of the rods are:

First rod: a

Second rod: 2a

Third rod: 3a

Fourth rod: 4a

Fifth rod: 5a

Now, to find the total length (L), add up the lengths of all the rods:

L = a + 2a + 3a + 4a + 5a

Combine like terms:

L = (1 + 2 + 3 + 4 + 5) · a

The sum of the first n natural numbers is given by the formula n(n + 1)/2, so in this case:

L = 5 · 6/2 · a

Simplify the expression:

L = 15a

So, the formula for the total length L in terms of a is L = 15a.

The complete question is:

Here are five straight rods.

All measurements are in centimeters.

The total length of the five rods is L" " cm.

This system has one solution. y=x2−3x+7y=3x−2 What is the y-coordinate of the solution? Enter your answer in the box.

Answers

Answer:
y = 7

Explanation:
The first given equation is:
y = x² - 3x + 7 ...........> equation I
The second given equation is:
y = 3x - 2 ..............> equation II

Substitute with equation I in equation II and solve for x as follows:
y = 3x - 2
x² - 3x + 7 = 3x - 2
x² - 3x + 7 - 3x + 2 = 0
x² - 6x + 9 = 0
(x-3)² = 0
This means that:
x = 3

Now, substitute with the value of x in equation II to get the y as follows:
y = 3x - 2
y = 3(3) - 2
y = 7

Explanation:

The student is asked to find an expression equivalent to –25(15 – 20d + 5c). To do this, we will apply the distributive property to multiply –25 by each term inside the brackets. This gives us:

–25 × 15 = –375–25 × (–20d) = 500d–25 × 5c = –125c

Combining these we get the expression –375 + 500d – 125c. When we look at the options provided, none are equivalent to the expression we derived. Therefore, the correct answer is:
