Select the graph that represents the equation y= 2/3x-3

Answer:

0.102 s

Step-by-step explanation:

Given the following :

Initial speed (u) = 1 m/s

How long does it take the bean bag to reach maximum height?

At maximum height, the final velocity v = 0

Acceleration due to gravity g = - ve (upward motion) =? - 9. 8m/s²

Using the relation:

v = u + gt

0 = 1 - 9.8t

9.8t = 1

t = 1 / 9.8

t = 0.102 s

Answer:

0.10

Step-by-step explanation: Khan Academy

the function is x^2-9, so all you have to do is replace x with a number. for example, 2.

so 2^2-9 is -5. the plot would be 2, -5. basically, plug in a number to be the x coord, and whatever number you get will be your y coord.

after you graph a few plots (doing the same thing above), draw a line through all of them.

if the line goes up towards the right top corner, it's increasing. if it goes down the right bottom corner, it's decreasing.

Answer:

6 feet

Step-by-step explanation:

240 feet : 10 inches

24 feet    : 1 inch

? feet       : 1/4 inch

to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4

24 ÷ 4 = 6

Answer:

6 ft

Step-by-step explanation:

First, make this visually understandable using a ratio:

240 ft = x ft

10 in     [tex]\frac{1}{4}[/tex] in

To find the change between the inches,

1/4 ÷ 10 = 0.025

Use this same amount to find x ft:

240 (0.025) = 6

x = 6 ft

To double-check:

240/10 = 24

6/0.25 = 24

16. [tex]j = \frac{17-15q}{4}[/tex]

17. [tex]q = \frac{17 - 4j}{15}[/tex]

Step-by-step explanation:

15. -2.3(8.6)²+ 3.5(8.6)= -140.008

16.

15q + 4j = 17

4j = 17 - 15q

Answer:

It is stucked on the 9th floor

Step-by-step explanation:

We want to know the floor on which the elevator is stucked.

The main lobby is the ground floor and has a value of 0 floor

Ascends four floors with 6 people from the lobby

It is now on floor 4

Ascends another two so it is now on floor 4 + 2 = 6

Ascends another 2, then descend descends 3

That will be 6 + 2 -3 = 5th floor

Ascends 8 more , then descend 2

That will be 5 + 8 -2 = 11

Descends another 2, making 11 - 2 = 9

It is stucked on floor 9

Kindly note, when it ascends, that is a positive value, when it descends, that is a negative

Step-by-step explanation:

Given

[tex]\frac{2}{5\sqrt{3} }[/tex]

To rationalise the denominator, multiply the numerator/ denominator by [tex]\sqrt{3}[/tex]

= [tex]\frac{2\sqrt{3} }{5\sqrt{3}(\sqrt{3}) }[/tex]

= [tex]\frac{2\sqrt{3} }{15}[/tex]

-----------------------------------------------------------------------

Given

[tex]\frac{\sqrt{5}+2 }{\sqrt{5}-2 }[/tex]

Multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of [tex]\sqrt{5}[/tex] - 2 is [tex]\sqrt{5}[/tex] + 2 , then

= [tex]\frac{(\sqrt{5}+2)(\sqrt{5}+2) }{(\sqrt{5}-2)(\sqrt{5}+2) }[/tex] ← expand numerator/denominator using FOIL

= [tex]\frac{5+4\sqrt{5}+4 }{5-4}[/tex]

= [tex]\frac{9+4\sqrt{5} }{1}[/tex]

= 9 + 4[tex]\sqrt{5}[/tex]

Answer:

I believe it would be no real number

Step-by-step explanation:

If you use PEMDAS and multiply the (5-2c) by 2 you get 10-4c. You'd then have to isolate the c and move it over by adding 4c to each side, which would make the inequality 0>10 or even if you flipped it to be -10>0. Both of which are false.

Answer:

[tex]y=\frac{-1}{3}x-4[/tex]

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope m

[tex]m=\frac{-2-(-7)}{-6-9}[/tex]

[tex]m=\frac{-2+7}{-15}[/tex]

[tex]m=\frac{5}{-15}[/tex]

[tex]m=\frac{-1}{3}[/tex]

[tex]y=\frac{-1}{3}x+b[/tex]

Step 3: Find y-intercept b

[tex]-7=\frac{-1}{3}(9)+b[/tex]

[tex]-7=-3+b[/tex]

[tex]-4=b[/tex]

Step 4: Write linear equation in slope-intercept form

[tex]y=\frac{-1}{3}x-4[/tex]

Answer:

2y + 4 = 6x - 7

2y = 6x - 11

2y + 6x = -11

Answer:

2y+4=6x-7

take 4 from both sides

2y=6x-3

divide each side by 2

y=6x-3

3) 3×c+3×7

Step-by-step explanation:

Hey there!

The given points are; (4,4) and (1,2) as (x1,y1) and (x2,y2).

Note: Use double point formula for the equation.

Now;

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Put all values.

[tex](y - 4) = \frac{2 - 4}{1 - 4} (x - 4)[/tex]

Simplify it.

[tex](y - 4) = \frac{ - 2}{ - 3} (x - 4)[/tex]

[tex](y - 4) = \frac{2}{3} (x - 4)[/tex]

[tex](y - 4) = \frac{2}{3} x - \frac{2}{3} \times 4[/tex]

[tex]y = \frac{2}{3}x - \frac{8}{3} + 4 [/tex]

[tex]y = \frac{2}{3} x - \frac{8 + 12}{3} [/tex]

[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]

Therefore, the equation is; y = 2/3x+4/3.

Answer:

A) 1.3 represents the number of foodbank users in thousands in the year 2006

B) 0.81 per year

C) 124.79%

D) the doubling rate is less than a year.

Step-by-step explanation:

A) We are given N(t) = 1.3e^(0.81t) where t in thousands the number of years since 2006. N(t) is in thousands

Thus, in 2006,t = 0.

So, N(0) = 1.3e^(0.81 × 0)

N(0) = 1.3

Thus,1.3 represents the number of foodbank users in thousands in the year 2006

B) From the question, we see that the continuous growth rate is 0.81t.

This is 0.81 per year

C) The exponent of the growth rate is e^(0.81t).

Thus gives; 2.2479^(t)

This means the annual growth factor for each year is 2.2479.

Thus,annual percent growth rate is;

(2.2479 - 1) × 100% = 124.79%

D) From C above we saw that the annual percent growth rate is more than 100%. This means that it takes less than a year for the number of users to be doubled.. Thus, the doubling rate is less than a year.

Answer: 64462 visitors

Step-by-step explanation:

In September, a website had 12,514 visitors.

In October, the website had 13,460 more visitors than it did in September. This will be:

= 12514 + 13460

= 25974

The website had the same number of visitors in November as it did in October.

September = 12514 visitors

October = 25974 visitors

November = 25974 visitors

Total visitors = 12514 + 25974 + 25974

= 64462 visitor

The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.

An equilateral triangle is a triangle that has all its sides equal to each other.

Therefore,

3x - 5 = 5y - 4 (equilateral triangle)

3x - 5y = 1

Therefore,

y + 12 = 3x - 5 (Isosceles triangle)

y - 3x = - 17

Hence,

3x - 5y = 1

- 3x + y = - 17

-4y = -16

y = -16 / -4

y = 4

Therefore,

3x = 1 + 5(4)

3x = 21

x = 21 / 3

x = 7
