Answer:

5.06

Step-by-step explanation:

1 2/3 = 1/3

x = 1                                         (cross multiply)

1/3 x = 1 2/3                             (divide both sides by 1/3)

x = 5.06

Answer:

B

Step-by-step explanation:

it is exponential growth because the graph isn't linear and it the rate of change increases, so the only possible answer is b.

Given graph is representing the graph of exponential growth.

" Graph is defined as the representation of relation between variables on the coordinates plane along x-axis and y-axis."

According to the question,

As per the given graph,

A. Linear decreasing : It is not a graph of linear decreasing function as it is not representing a straight line which intersect y-axis at (0, k) and x-axis at (h,0).

B. Exponential growth: For exponential growth [tex]y = ab^{x}[/tex] a>0 , b>1.

This graph representing the condition for exponential growth.

C. Exponential decay :  For exponential decay [tex]y = ab^{x}[/tex] a >0 , 0 < b < 1.

Therefore , it is not a graph of exponential decay.

D. Linear increasing : It is not a graph of linear increasing function as it is representing a straight line which starts from (0,0) and increasing towards the first quadrant.

Hence, given graph is representing the graph of exponential growth.

Answer:

3. 1/9 feet^3

Step-by-step explanation:

First, find the volume of one cube.

The volume of a cube can be found using the following formula:

V=s^3

We know that s, the side length is 1/3 feet. Therefore, we can substitute 1/3 ft in for s.

V= (1/3 ft)^3

Evaluate the exponent.

1/3 ft^3

=1/3 ft * 1/3 ft* 1/3 ft

=1/9 ft^2*1/3 ft

= 1/27 ft^3

V= 1/27 ft^3

Now find the volume of 3 cubes. We know the volume of one cube is 1/27 ft^3, therefore we can multiply 1/27 ft^3 by 3.

1/27 ft^3 * 3

Multiply 1/27 and 3.

1/27 * 3/1

=(1*3)/(27*1)

=3/27

=1/9

V= 1/9 ft^3

The volume of 3 cubes is 1/9 cubic feet, and choice 3 is correct.

Answer:

1/9; C

Step-by-step explanation:

V=s*s*s

Side Length: 1/3

V=1/3*1/3*1/3

V=1/27

1/27*3= 3/27

3/27 simplified eqauls 1/9

Answer:

a) How much water was released during the flood?

14878080000 cubic feet or 14,878,080,000ft³

b) What percentage of the dam was released during the flood?

0.78%

Step-by-step explanation:

a) How much water was released during the flood?

The first step would be to find out how many seconds are in a week

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

Hence, the number of seconds in a week =

1 week × (7 days/1 week)× (24 hours/1 day )×( 60 minutes/1 hour) ×( 60 seconds/1 minute)

= 604800 seconds

Therefore, the quantity of water released per week =

604800 seconds × 24,600 cubic feet per second

= 14,878,080,000 cubic feet or 14,878,080,000ft³

b) What percentage of the dam was released during the flood?

This is calculated as quantity released during the week ÷ Quantity of water in the dam × 100%

Quantity of water released during the flood in a week = 14,878,080,000 cubic feet

Quantity of water in the dam= 1,900,000,000,000 cubic feet of water

Percentage of the dam released during the flood =

14,878,080,000 cubic feet ÷ 1,900,000,000,000 × 100

= 0.7830568421%

Approximately = 0.78%

Answer:

The answer is explained below

Step-by-step explanation:

The question is not complete we need point P and point Q.

let us assume P is at (3,1) and Q is at (-2,4)

To find the coordinate of the point that divides a line segment PQ with point P at [tex](x_1,y_1)[/tex] and point Q at [tex](x_2,y_2)[/tex] in the proportion a:b, we use the formula:

[tex]x-coordinate:\\\frac{a}{a+b}(x_2-x_1)+x_1 \\\\While \ for\ y-coordinate:\\\frac{a}{a+b}(y_2-y_1)+y_1[/tex]

line segment PQ  is divided in the ratio 5:3 let us assume P is at (3,1) and Q is at (-2,4). Therefore:

[tex]x-coordinate:\\\frac{5}{5+3}(-2-3)+3 \\\\While \ for\ y-coordinate:\\\frac{5}{5+3}(4-1)+1[/tex]

Answer:

Option (3)

Step-by-step explanation:

By applying mean proportional theorem in the given triangle ABC,

[tex]\frac{\text{AD}}{\text{BD}}=\frac{\text{BD}}{\text{CD}}[/tex]

AD × CD = BD²

(x)(4x) = (10)²

4x² = 10²

4x² = 100

x² = [tex]\frac{100}{4}[/tex]

x = [tex]\sqrt{25}[/tex]

x = 5

Therefore, measure of segment AD Or x = 5 units

Option (3) will be the answer.

The y-intercept of the first inequality is -1.

The y-intercept of the second inequality is +1.

The fourth graph has these correct.

Answer:

1

Step-by-step explanation:

The slope of the line (when in point-slope form) will be the coefficient of the term on the right side of the equation. In this case that is 1.

Answer:

1

Step-by-step explanation:

y - 3 = (x - 2)

Solve for y. Then when the equation is in the slope-intercept form, y = mx + b, m is the slope.

y - 3 = x - 2

Add 3 to both sides.

y = x + 1

Compare to y = mx + b: y = 1x + 1

m = 1

Answer: The slope is 1.

Answer:

The value of n for which xₙ₋₂ + xₙ₋₁ + xₙ = 68 is n = 9

Step-by-step explanation:

The nth term of Fibonacci number is given by the following relation;

[tex]F_n = \dfrac{(1 + \sqrt{5} )^n - (1 - \sqrt{5} )^n }{2^n\sqrt{5} }[/tex]

Given that we have ;

[tex]\Sigma x_n = \dfrac{(1 + \sqrt{5} )^{n-2} - (1 - \sqrt{5} )^{n-2} }{2^{n-2}\sqrt{5} } + \dfrac{(1 + \sqrt{5} )^{n-1} - (1 - \sqrt{5} )^{n-1} }{2^{n-1}\sqrt{5} }+\dfrac{(1 + \sqrt{5} )^{n} - (1 - \sqrt{5} )^{n} }{2^{n}\sqrt{5} }[/tex]When n = 3, we have;

∑xₙ = 4

When n = 4 we have

∑xₙ = 4

When n = 6 we have

∑xₙ = 16

When n = 9 we have

∑xₙ = 68

Therefore, we have the value of n for which xₙ₋₂ + xₙ₋₁ + xₙ = 68 is n = 9.

Answer:

28 cm

Step-by-step explanation:

V=a³

a= ∛V= ∛21952 cm³ = 28 cm

Answer:

Step-by-step explanation:

28 is the answer because you have to find the cube root of the volume. This is because a cube has equal sides so it means that the sides have to be equal. When you find volume, you have to multiply the length, width, and height. So you have to find the cube root of 21952. The cube root is 28.

Answer:

(-3,0) (1,0)

Step-by-step explanation:

y=2x^2+ 4x - 6

Factor out the greatest common factor

y = 2( x^2 +2x -3)

Factor inside the parentheses

y = 2( x+3)(x-1)

Setting the equation equal to zero to find the x intercepts

0 =  2( x+3)(x-1)

Using the zero product property

x+3 = 0  x-1 =0

x = -3  x = 1

The x intercepts are

(-3,0) (1,0)

Answer:

50 degrees

Step-by-step explanation:

Theorem: The Exterior angle of a triangle is equal to the sum of two opposite interior angles.

By the theorem stated above:

m∠3+m∠5=m∠1

2x+20+30=3x

3x-2x=50

x=50

The value of x is 50 degrees.

Answer:

50

Step-by-step explanation:

"sqrt" stands for "square root"

=======================================================

Explanation:

Angle C is 60 degrees because adding the angles gets A+B+C = 180. Put another way, C = 180-A-B. Therefore, C = 180-30-90 = 60.

We have a 30-60-90 triangle with

Check out the diagram below.

----------

From here, we use the 30-60-90 triangle template. The short leg is x, the hypotenuse is 2x and the long leg is x*sqrt(3). The area of this template triangle is

area = 0.5*base*height

area = 0.5*(short leg)*(long leg)

area = 0.5*x*(x*sqrt(3))

area = 0.5*x^2*sqrt(3)

set this equal to 32*sqrt(3) and you should find that 0.5x^2*sqrt(3) = 32*sqrt(3) solves to x = 8

----------

Therefore we can say,

Answer:

Option 1

Step-by-step explanation:

To check that quadrilaterals ABCD and EFGH are similar, we'll take the proportion of any of their two sides and check whether they are equal or not.

=> [tex]\frac{3}{2} = \frac{5}{4}[/tex]

Cross Multiplying

=> 3 * 4 = 2 * 5

=> 12 ≠ 10

Since, the proportion is not equal, the quadrilaterals are not similar
