Answer:

The tree's height is 142.24 cm.

Step-by-step explanation:

There are 12 inches in a foot. This means that 4 feet equal 4 * 12 = 48 inches. Since there are 8 more inches, you add 8 to 48. The sum is 56. There are 56 inches in 4 feet and 8 inches.

Now, to convert:

56 * 2.54 = 142.24 (inches to centimeters)

The tree's height is 142.24 cm.

Two numbers that meet the condition are a = -10 and b = 2, and the quotient between these is larger than the product.

We have two numbers a and b with different sign.

Let's say that a is negative and b positive.

We know that the absolute value of a is divisible by the absolute value of b.

|a|/|b|

Then we have that |a| ≥ |b|

An example of two numbers that meet these conditions are:

a = -10

b = 2

Where:

|-10|/|2|  = 10/2 = 5

Now, the product between the integers will give a large negative number, in this case:

-10*2 = 20

and the quotient will give a smaller, in absolute value, negative number:

-10/2 = -5

Then we can see that the quotient is larger (as both are negative numbers, and the quotient is closer to zero).

Answer:

vertex

Step-by-step explanation:

Given:

Two points that are close to the line of best fit are (2,70) and (4.5, 90).

To find:

Th equation of best fit line using the given two points.

Solution:

We know that, if a line passes through the two points, then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Two points (2,70) and (4.5, 90) are close to the best fit line.

Consider the two points (2,70) and (4.5, 90). So, the equation of line is

[tex]y-70=\dfrac{90-70}{4.5-2}(x-2)[/tex]

[tex]y-70=\dfrac{20}{2.5}(x-2)[/tex]

[tex]y-70=8(x-2)[/tex]

[tex]y-70=8x-16[/tex]

Adding 70 on both sides, we get

[tex]y=8x-16+70[/tex]

[tex]y=8x+54[/tex]

Therefore, the equation of best fit line is [tex]y=8x+54[/tex].

Answer:

Gloria would text 360 words if Erica texted 500 words.

Step-by-step explanation:

Let 'y' be the number of words Gloria texts

Let 'x' be the number of words Erica texts

Given that the relationship is  proportional

y ∝ x

y = kx

where 'k' is called the constant of proportionality

Given

substituting the values to determine the constant of proportionality 'k'

k = y / x

   = 18 / 25

Thus, the constant of proportionality = k = 18/25

When Erica texted 500 words, we need to determine the number of words Gloria will text.

so

k = 500

y = ?

k = y / x

y = kx

  = 18 / 25 × 500

  = 360 words

Thus, Gloria would text 360 words if Erica texted 500 words.

These are the characteristics of the exponential growth and exponential decay functions

Properties of Exponential Growth Functions

The function is an increasing function; y will increase as x will increase. Range: If a>0, the range is {positive real numbers} The graph is continually above the x axis. Horizontal Asymptote: when b>1, the horizontal asymptote is the negative x axis, as x will become huge negative.

Properties of Exponential Decay Functions

The feature y=f(x) function represents decay if k < 0. The function is a reducing function; y decreases as x will increase. Range: If a>0, the range is {positive real numbers } The graph is always above the x axis.

Answer:

David gets £34, Egil gets £119 and Frances gets £153.

Step-by-step explanation:

Let the amount of money David gets be 2x, Egil be 7x and Frances be 9x.

7x = 2x + 85

7x - 2x = 85

5x = 85

x = 85 ÷ 5

x = 17

David (2x) = 2 × £17

                 = £34

Egil (7x) = 7 × £17

             = £119

Frances (9x) = 9 × £17

                     = £153

Answer:

34.8 N at 2.5 degrees from the positive x-axis

Step-by-step explanation:

From the given information:

The force F makes an angle A with the positive x axis can be expressed in terms horizontal and vertical components.

[tex]F_x = F cos A\\\\ F_y = Fsin A[/tex]

Given that

[tex]F_1 = 50 \ N[/tex]

[tex]\theta_1 = 30 ^0 \ \ \ (x-axis)[/tex]

[tex]F_{1x} = F_1 \times Cos A_1[/tex]

=  50 × cos 30

= 43.3 N

[tex]F_{1y} = F_1 \times Sin \ A_1[/tex]

= 50 × sin 30

= 25 N

Similarly;

[tex]F_2 = 25 \ N[/tex]

[tex]\theta_2 = 250 ^0 \ \ \ ( x-axis)[/tex]

[tex]F_{2x} = F_2 \times cos \ A_2[/tex]

= 25 × cos 250

= - 8.55 N

[tex]F_{2y} = F_2 \times A_2[/tex]

= 25 × sin 250

= -23.5 N

The total net force;

[tex]F_{net} = F_{(net)}_x + F_{(net)}_y[/tex]

[tex]F_{net} = (F_{1x} + F_{2x} ) i + (F_{1y} + F_{2y} )j[/tex]

[tex]F_{net} = (43.3 - 8.55) i + (25-23.5 ) j[/tex]

[tex]F_{net} =34.75 i + 1.5 j[/tex]

[tex]|F_{net} | = \sqrt{F_{net}_x^2 + F_{net}_y^2}[/tex]

[tex]|F_{net} | = \sqrt{34.75^2 + 1.5^2}[/tex]

[tex]|F_{net} | = 34.8 \ N[/tex]

Finally, the direction of the angle for the net force is:

[tex]tan \theta = \dfrac{F_{net_y}}{F_{net_x}}[/tex]

[tex]\theta = tan^{-1} \Big (\dfrac{F_{net_y}}{F_{net_x}} \Big)[/tex]

[tex]\theta = tan^{-1} \Big (\dfrac{1.5}{34.75}} \Big)[/tex]

[tex]\theta = tan^{-1}( 0.043165)[/tex]

[tex]\theta \simeq 2.5^0\ with \ positive \ x-axis[/tex]

The probability that perhaps the stock returns will be less than 18.5% is 0.542.

In most cases where the possible study population is large, a normal distribution is chosen. Apart from its easier application than that of other distribution methods, this is the primary reason for its efficiency.

Let X be the annual return on common stocks throughout 1926 to 1992.

The average of X is 16.5%.

X has a standard deviation of 19%.

Assume X is regularly distributed.

X∼N(μ,σ)

∼N(16.5,19)

The likelihood that stock returns seem to be less than 18.5% is calculated using the Z-table, as shown below.

P(X < 18.5) = [tex]P\left(\frac{X-\mu}{\sigma} < \frac{18.5-16.5}{19}\right)[/tex]

                  = P(Z < 0.1053)

                   = 0.542

The probability that perhaps the stock returns will be less than 18.5% is 0.542.

What is the area of a square?

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

[tex]Sales\ Price = \$57.12[/tex]

Step-by-step explanation:

Given

[tex]Price = \$84.00[/tex]

[tex]Markdown = 32\%[/tex]

Required

Determine the sales price

First, we calculate the markdown price.

This is calculated by multiplying the original price the markdown percentage

[tex]Markdown\ Price = \$84.00 * 32\%[/tex]

Convert % to decimal

[tex]Markdown\ Price = \$84.00 * 0.32[/tex]

[tex]Markdown Price = \$26.88[/tex]

The sales price is then calculated as:

[tex]Sales\ Price = \$84.00 - \$26.88[/tex]

[tex]Sales\ Price = \$57.12[/tex]

Hence, the sales price after markdown is $57.12
