07 minutes
O11 minutes
4x-5, where x is the
F

Answers

Answer 1

The time taken for the person to get to school based on the equation will be 7 minutes.

How to calculate the time?

From the information given, the equation is given as:

g(x) = x⁴ - 3x² + 4x - 5

Then, we'll put 2 as x. This will be:

= 2⁴ + 3(2)² + 4(2) - 5

= 16 - 12 + 8 - 5

= 7

Therefore, the time taken for the person to get to school based on the equation will be 7 minutes.

Complete Question:

A rectangular prism has a length of 7 m, a height of 5 m, and a volume of 140 m³. What is the width? A prism has a length of 7 meters, width of w, and height of 5 meters.

Which steps are correct? Check all that apply.

a) Substitute the known values into the formula: 140 = 7(w)(5).

b) Substitute the known values into the formula: 7 = 140(w)(5).

c) Substitute the known values into the formula: 5 = 7(w)(140).

d) Solve for the unknown: w = 4 m.

e) Solve for the unknown: w = 7 m.

f) Solve for the unknown: w = 2 m.

Answer:

a) Substitute the known values into the formula: 140 = 7(w)(5).

d) Solve for the unknown: w = 4 m.

Step-by-step explanation:

The steps that are correct are Options a) and d). This is because:

Step 1

The volume of a rectangular prism is calculated as:

Volume of a rectangular prism = Length (l) × Width(w) × Height(h)

The unit of the volume or a rectangular prism is in cubic metres (m³)

In the question, we are asked to find the unknown value which is the width and we were given the following known values:

Length = 7 m,

Height = 5 m

Volume = 140 m³

Step 2

Solve for the unknown value( Width)

Volume of a rectangular prism = Length (L) × Width(W) × Height(H)

140m³ = 7m × Width(m) × 5m

140m³ = 35m² × Width(m)

Width(w) = 140m³ ÷ 35m²

Width(w) = 4m

Hence, the unknown Width(w) = 4m

From the above explanation we can see that the correct steps is Option a) and Option d)

Answer:

Step-by-step explanation:

Volume of rectangular prism= Length x width x height

V=L x W x H

140=7 x W x 5

140= 35 x w

W= 140/35

W= 4

In a survey, 60% of those questioned chose winter as their favorite season.
If 48 people chose winter, then how many people were surveyed?

A.29

B.32

C.80

D.128

Answers

Answer:

C. 80

Step-by-step explanation:

Let the number of people were surveyed is x.

We have 60% of x is 48 people.

Set this as equation and solve:

60% of x = 48x*60/100 = 480.6x = 48x = 48/0.6x = 80

Correct choice is C.

Answer:

C.  80

Step-by-step explanation:

Given:

60% = 48 people

Let x be the total number of people surveyed.

Set up a ratio of people to percentage and solve for x:

[tex]\implies \sf 48 : 60 = x : 100[/tex]

[tex]\implies \sf \dfrac{48}{60}=\dfrac{x}{100}[/tex]

[tex]\implies \sf x=100 \cdot \dfrac{48}{60}[/tex]

[tex]\implies \sf x=\dfrac{4800}{60}[/tex]

[tex]\implies \sf x=\dfrac{480}{6}[/tex]

[tex]\implies \sf x=80[/tex]

Therefore, the total number of people who were surveyed was 80.

calculates the sum of the first 8 terms of an arithmetic progression starting with 3/5 and ending with 1/4

Answers

We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

How to get the sum of the first 8 terms?

In an arithmetic sequence, the difference between any two consecutive terms is a constant.

Here we know that:

[tex]a_1 = 3/5\\a_8 = 1/4[/tex]

There are 7 times the common difference between these two values, so if d is the common difference:

[tex]a_1 + 7*d = a_8\\\\3/5 + 7*d = 1/4\\\\7*d = 1/4 - 3/5 = (5 - 12)/20 = -7/20\\\\d = -1/20[/tex]

Then the sum of the first 8 terms is given by:

[tex]3/5 + (3/5 - 1/20) + (3/5 - 2/20) + ... + (3/5 - 7/20)\\\\8*(3/5) - (1/20)*(1 + 2 + 3+ 4 + 5 + 6 + 7) = 3.4 = 34/10 = 17/5[/tex]

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

What is the equation of the function described?

Answers

The equation for the sinusoidal function described is given as follows:

[tex]y = 4\cos{\left(\frac{1}{2}x\right)} + 2[/tex]

What is a sinusoidal function?

We want a function with a y-intercept at it's maximum value, hence we use the cosine equation, given by:

[tex]y = A\cos{\left(\frac{2\pi}{B}x\right)} + C[/tex]

In which:

2A is the amplitude, which is the difference between the largest and smallest value.B is the period.C is the vertical shift, considering that the standard cosine function has range between -A and A.

The amplitude is of 8, hence 2A = 8 -> A = 4. This would represent a function between -4 and 4, but we want between -2 and 6, hence the vertical shift is of C = 2.

As for the period, we have that:

[tex]B = 4\pi[/tex]

Step-by-step explanation:

Hello there!

We have two methods to solve this problem.

Substitution methodElimination method.

We will limit ourself to Substitution method.

3x – 2y = -4.................... 1.

4x + 2y = 25................... 2.

First lets manipulate eq.2 in terms of y.

4x + 2y = 25

2y = 25 - 4x

y = 25/2 - 2x .............. eq.3

Substitute eq.3 into eq.1

3x – 2(25/2 -2x) = -4

Solve for x.

Opening the brackets

3x - 25 - 4x = -4

-x = 21

x = -21

Substitute x into equation 3

y = 25/2 - 2x

=> y = 25/2 - 2(-21)

= 54.5

In terms of x and y; (x,y)

= (-21, 54.5)

A motorboat travels 464 kilometers in 8 hours going upstream and 644 kilometers in 7 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?

Rate of boat in still water ______km/h

Rate of current: _______ km/h

Answers

Let's say you are paddling at 5mph and the current is 3 mph. Going upstream, you are going 2 mph and downstream, 8 mph.

8(b - c) = 464

7(b + c) = 644

b - c = 58

b + c = 92

Adding the two together

2b = 150

b = 75

75 - c = 58

c = 17

The boat's speed is 75 mph and the current's speed is 17 mph.
