Answer 1

Answer:

x=4

Step-by-step explanation:

both angles add up to 90* because it is a right angle

10x + 12x + 2 = 90

22x + 2 = 90

subtract 2 from both sides of the equation

22x = 88

divide both sides by 22

x = 4

Examine the data below for a stalk of corn. Logarithmic regression Use logarithmic regression to find an equation of the form y = a b ln(x) to model the data. A = b =.

Answers

The value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

What is logarithmic regression?

Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.

The data of the table for the day and height of the stalk of corn is listed below.

Day (x)                9    12    22    40    

Height (y) in        5    17    45    60  

Mean of x values,

[tex]m_x=\dfrac{9+12+22+40}{4}\\m_x=17.5581[/tex]

Mean of y values,

[tex]m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75[/tex]

For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,

[tex]y = -76.2038+37.6735\ln(x)[/tex]

Compare it with the following logarithmic regression equation, we get

[tex]y = a+b\ln(x)[/tex]

[tex]a=-76.2038\\b=37.6735[/tex]

Hence, the value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

eduardo has 4 1/2 yard of rope light. Exactly how many more yard does he need to finish the car's ceiling

Answers

Answer:

2 1/6

Step-by-step explanation:

Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.

4 1/2 -> 9/2

6 2/3 -> 20/3

Next, make the denominators the same by multiplying each fraction by the denominator of the other.

9/2 * 3 = 27/6

20/3 * 2 = 40/6

Then you can subtract the numerators because the denominators are the same:

40/6-27/6= 13/6

Then you can convert to a mixed fraction if need be.

Timothy invested a total of $7,500 in two accounts. One account pays 3% interest annually; the other pays 2% interest annually. At the end of the year, Timothy earned a total of $175 in interest. Write and solve a system of equations' to find how much money Timothy invested in each account.
Timothy invested ___in 3% account and ______in the 2% account

Answers

Answer:

Timothy invested $2500 in 3% account and $5000 in the 2% account

Step-by-step explanation:

Let the investments be x and y.

Required equations are:

x + y = 75000.03x + 0.02y = 175

Solve the system by elimination, multiply the second equation by 50 and subtract the first one:

50(0.03x) + 50(0.02y) - x - y = 50(175) - 75001.5x - x = 12500.5x = 1250x = 2500

Find the value of y:

2500 + y = 7500y = 5000

Write an equation for the translation of y = 4/x that has the given asymptotes x = 2, y = 2

Answers

According to the given asymptotes, the equation for the translation of the function is:

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

What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

In this problem, the function is:

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

The vertical and horizontal asymptotes are, respectively, given by: x = 0, y = 0.

To have the desired asymptotes, the function has to be shifted 2 units to the right and 2 units up, hence it is given by:

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

please answer the following and give a good explanation

Answers

Answer:

x = 8

z = 15

y = 118°

Step-by-step explanation:

First, we know that these are similar. That means that if we know which angles correspond to each other, those are equal, and the sides that correspond to each other have a common ratio. I went ahead and rotated PQRS so that it visually aligns with WXYZ -- that image is attached. We can do this because similar shapes must have the same angles, so aligning the angles works here. Using that, we can see that, based on the angles, QR matches up with XY, WZ matches up with PS, and so on.

We can then say that there is a common ratio between the corresponding sides.

WZ/PS = XW/PQ = ZY/RS = 9/6 = 12/x = z/10

9/6 simplifies to 3/2, so we have

3/2 = 12/x

multiply both sides by x to no longer have it as a denominator

3 * x / 2 = 12

multiply both sides by 2 and divide both sides by 3 to isolate x

x = 8

3/2 = z / 10

multiply both sides by 10 to isolate z

z = 15

In the corresponding figures, we can see that y matches up with ∠WXY. Thus, the two angles are equal and y = 118°

What speed will a fan turn if the drive motor is turning at 1250 RPM, the motor pulley is 4 inches in diameter, and the fan pulley is 8 inches in diameter

Answers

The speed the fan will turn is 625 rpm

Linear speed

Since they fan and the pulley ahve the same linear speed v = rω where

r = radius of pulley and ω = angular speed.

Then

r₁ω₁ = r₂ω₂ where

r₁ = radius of fan pulley = 8 in/2 = 4 in, ω₁ = angular speed of fan pulley, r₂ = radius of motor pulley = 4 in/2 = 2 in, ω₂ = angular speed of motor pulley = 1250 rpm

Angular speed of fan pulley

Making ω₁ subject of the formula, we have

ω₁ = r₂ω₂/r₁

Substituting the values of the variables into the equation, we have

ω₁ = r₂ω₂/r₁

ω₁ = 2 in × 1250 rpm/4 in

ω₁ = 1250 rpm/2

ω₁ = 625 rpm

So, the speed the fan will turn is 625 rpm

Find the two numbers.

Answers

Answer: The numbers are 96 and 56

Step-by-step explanation:

So, 2y=112, making y=56

If you plug y=56 into x+y=152, you will get x=96

An equilateral triangle (all 3 sides are the same length) sits on top of a square. They both share the side AB

Answers

Answer:

6x +15

Step-by-step explanation:

To solve for the perimeter of the triangle, we need to find the length of each side.

(a +b)² = a² +2ab +b²

Let's factorise the expression for the area of the square:

Area of square

= 4x² +20x +25

= (2x +5)²

Since area of square= side ×side, length of a side of the square is the square root of its area. We are also given that the side of the square is AB.

(AB)²= (2x +5)²

Taking the square root of both sides:

AB= 2x +5

The perimeter is the sum of the lengths of all of its sides.

Perimeter of the triangle

= 3(AB)

= 3(2x +5)

= 6x +15
