Equation of Line

The equation of a straight line is y=mx + c.  y = m x + c m is the gradient and c is the height at which the line crosses the y -axis, also known as the y -intercept.

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x, y to form an algebraic equation, which is referred to as an equation of a line.

In the given question, we are asked to find several values relating to the graph attached.

5) The point of origin on the graph is at (0,0) because the graph passes through the center along the straight line.

6) The constant of proportionality (k) is the value before the variable x.

The equation of the line is y = 3x.

The constant of proportionality of the equation is equal to 3.

7) The value of the ratio k is given as y/x

Step-by-step explanation:

Suppose you know students at school are, on average, 68 inches tall with a standard deviation of 4 inches. If you sample 36 students, what is the probability their average height is more than 70 inches?

Answers

Answer:

0.135% or 0.00135

Explanation:

• The population mean height = 68 inches

,

• The population standard deviation = 4 inches

,

• Sample Size, n = 36

First, find the sample standard deviation:

[tex]\sigma_x=\frac{\sigma}{\sqrt{n}}=\frac{4}{\sqrt{36}}=\frac{4}{6}=\frac{2}{3}[/tex]

Next, for X=70, find the z-score:

[tex]\begin{gathered} z-score=\frac{X-\mu}{\sigma_x} \\ z=\frac{70-68}{2\/3}=\frac{2}{2\/3}=3 \end{gathered}[/tex]

Since we are looking for the probability that their average height is more than 70 inches, we need to find:

• P(X>70)=P(z>3)

Using the z-score table:

[tex]P(z>3)=0.0013499[/tex]

The probability that their average height is more than 70 inches is 0.135%.

Answers

Explanation:

For a line to be parallel to another line, the slope will be the same

1st equation:

Since the slope of the first line = 2/5, the slope of the second line will also be 2/5

We would insert the slope and the given point into equation of line to get y-intercept of the second line:

A major record label has seen its annual profit decrease in recent years. In 2011, the label's profit was $128 million. By 2015, the label's profit had decreased by 30%.What was the record label company's profit in 2015? million dollars   Suppose the record label wants to increase its profit to $128 million by 2017. By what percent must the label's profit increase from its 2015 value to reach $128 million within the next two years? %

Answers

the company's profit in 2015 was $89,600,000 (89.6 million dollars)

43%

Explanation:

Profit in 2011 = $128 million

Profit in 2015 decreased by 30%

% decrease = (old price - new price)/old price

old price = Profit in 2011 , new price = Profit in 2015

30% = (128,000,000 - new price)/128000000

[tex]\begin{gathered} 30percent=\text{ }\frac{128,000,000 -newprice}{128000000} \\ 0.30\text{ = }\frac{128,000,000-newprice}{128000000} \\ \text{cross multiply:} \\ 0.3(128,000,000)\text{ = }128,000,000-newprice \end{gathered}[/tex][tex]\begin{gathered} 38400000\text{ = }128,000,000-newprice \\ \text{subtract }38400000\text{ from both sides:} \\ 38400000-\text{ }38400000\text{ = }128,000,000-38400000-newprice \\ \text{0 = 89600000 }-newprice \\ newprice\text{ = 89600000 } \end{gathered}[/tex]

Hence, the company's profit in 2015 was $89,600,000 (89.6 million dollars)

Percentage increase = (new price - old price)/old price

new price = 128million dollars , old price = 89.6 million dollars

% increase = [(128 - 89.6)in millions/(89.6) in millions] × 100

% increase = 38.4/89.6 × 100

% increase = 0.43 × 100

% increase = 43%

Hence, the label's profit must increase by 43% from its 2015 value to reach $128 million within the next two years

One angle measures 140°, and another angle measures (5k + 85)°. If the angles are vertical angles, determine the value of k.

Answers

The value of k when one angle measures 140°, and another angle measures (5k + 85)° and if the angles are vertical angles is 11.

What is vertical angles?

Vertical angles are angles opposite each other where two lines cross.

Note: Vertical angles are equal.

To calculate the value of k, we use the principle of vertical angle

From the question,

140 = (5k+85)°

Solve for k

5k = (140-85)5k = 55

Divide both side by the coefficient of k (5)

5k/5 = 55/5k = 11

Hence, the value of k is 11.

What is percentage?
A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything. As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics. Ram, for instance, scored 78% on his exam.

To find the percentage We divide 1550 by 3100 and then multiply by 100

We get

Find the vertex of the following equation: y = -5x² - 270x - 520

Answers

In order to find the vertex of this quadratic equation, first let's find the coefficients a, b and c from the standard form of the quadratic equation:

[tex]y=ax^2+bx+c[/tex]

Comparing with the given equation, we have a = -5, b = -270 and c = -520.

Now, let's calculate the x-coordinate of the vertex using the formula below:

[tex]\begin{gathered} x_v=\frac{-b}{2a} \\ x_v=\frac{-(-270)}{2\cdot(-5)} \\ x_v=\frac{270}{-10} \\ x_v=-27 \end{gathered}[/tex]

Using this value of x in the equation, we can find the y-coordinate of the vertex:

[tex]\begin{gathered} y_v=-5x^2_v-270x_v-520 \\ y_v=-5\cdot(-27)^2-270\cdot(-27)-520 \\ y_v=-5\cdot729+7290-520 \\ y_v=-3645+7290-520 \\ y_v=3125 \end{gathered}[/tex]

The Quad-II sub is at 3,645 feet below sea level (or -3,645 feet) and is ascending 76.9 feet per minute. If the ocean surface is at 0 feet, how many minutes (m) must elapse for the two submarines to reach the same depth? m = 290 minutes m = 145 minutes m = 53.8 minutes 4,863 - 76.9m = 3,645 - 81.1m O -4,863 + 81.1m = - 3,645 + 76.9m 0 - 4, 863 + 76.9m = -3, 645 + 81.1m – 4, 863 – 81.2m 2 – 3, 645 + 76.9m Om < 53.8 minutes

Answers

Unknown, the correct equation is:

- 4,863 + 81.1m = - 3,645 + 76.9m

And to solve for m, you use the standard form:

Like terms:

81.1m - 76.9m = -3,645 + 4,863

4.2m = 1,218

Answers

Answer

[tex]f^{\prime}(x)=6(x+1)(x^{2}+2x+7)^{2}[/tex][tex]f^{\prime}(1)=1200[/tex]

Explanation

Given

[tex]f\mleft(x\mright)=(x^2+2x+7)^3[/tex]

To find the derivative, we have to apply the chain rule:

[tex][u(x)^n]^{\prime}=n\cdot u(x)^{n-1}\cdot u^{\prime}(x)[/tex]

Considering that in our case,

[tex]u(x)=x^2+2x+7[/tex][tex]u^{\prime}(x)=2x+2+0[/tex]

and n = 3, then:

[tex]=3\cdot(x^2+2x+7)^{3-1}\cdot(2x+2)[/tex]

Simplifying:

[tex]f^{\prime}(x)=3\cdot2(x+1)(x^2+2x+7)^2[/tex][tex]f^{\prime}(x)=6(x+1)(x^2+2x+7)^2[/tex]

Finally, we have to replace 1 in each x in f'(x) to find f'(1):

[tex]f^{\prime}(1)=6((1)+1)((1)^2+2(1)+7)^2[/tex][tex]f^{\prime}(1)=6(1+1)(1+2+7)^2[/tex][tex]f^{\prime}(1)=6(2)(10)^2[/tex][tex]f^{\prime}(1)=6(2)(100)[/tex][tex]f^{\prime}(1)=12(100)[/tex][tex]f^{\prime}(1)=1200[/tex]

which expressions are equivalent to 9 divided by 0.3

Answers

Answer:

Step-by-step explanation:

So the answer would be 90 divided by 3 because all you have to do is multiply 0.3 times 10 and 9 times 10 simple hope this was understandable

30 will be the expressions that are equivalent to 9 divided by 0.3.

What is an equivalent expression?

In general, something is considered equal if two of them are the same. Similar to this, analogous expressions in maths are those that hold true even when they appear to be distinct. However, both forms provide the same outcome when the values are entered into the formula.

An expression is equivalent even when both sides are multiplied or divided with the same non-zero value.

The expression 9 divided by 0.3 can be written as 9/0.3

The expression that will be equivalent will be determined as:

= 9/0.3

= 90/3

= 30

where r is the radius of the cylinder and h is the height.

From the question, we have the following parameters:

[tex]\begin{gathered} diameter=4.8 \\ \therefore \\ r=\frac{4.8}{2}=2.4 \\ and \\ h=6.66 \end{gathered}[/tex]
