What is the period of y=-3cos(1/4x)

Answers

Answer 1

Answer:

Step-by-step explanation:

The standard form is y = a cos(bx + c) + d

the amplitude = |a| = 3

The period = [tex]\frac{2\pi }{b}[/tex] = [tex]\frac{2\pi }{\frac{1}{4} }[/tex] = [tex]8\pi[/tex]

on selling a fan for rupees 4700 A shopkeeper loses 6% at what price must he sell it to gain 6 percentage ​

Answers

Given:

Selling price of a fan = Rs.4700

Loss percent = 6%

To find:

The price at which he must sell it to gain 6 percentage.

Solution:

Let x be the cost price of the fan.

Loss percent = 6%

Selling price = Cost price - 6% of cost price

[tex]S.P.=x-\dfrac{6}{100}x[/tex]

[tex]S.P.=x-0.06x[/tex]

[tex]S.P.=0.94x[/tex]

Selling price of a fan = Rs.4700

[tex]4700=0.94x[/tex]

[tex]\dfrac{4700}{0.94}=x[/tex]

[tex]5000=x[/tex]

So, the cost price of the fan is Rs.5000.

Now, he need to sell this fan in 6% gain.

Selling price = Cost price + 6% of cost price

[tex]S.P.=5000+\dfrac{6}{100}\times 5000[/tex]

[tex]S.P.=5000+300[/tex]

[tex]S.P.=5300[/tex]

Therefore, he must sell it for Rs.5300 to gain 6 percentage.

6qt + 1p

Step-by-step explanation:

In a question like this, one can only combine like terms, in other words, the coefficients of the same variables. A coefficient is the number that is in front of a variable or the number a variable is being multiplied by.

The equation is;

4qt + 2qt + 1pt

4qt and 2qt are like terms, hence one can combine them.

The result is;

if cos=5 by 13 find the value of sin​

Answers

Answer:

The value of sin is : 12/13

Step-by-step explanation:

The formula for cosine of an angle is the length adjacent to that angle divided by the hypotenuse.

This means if ;

cos∅ = A/H  

then using this information and given that;

cos ∅ = 5 by 13

cos ∅ = 5/13

You can find the opposite side length from Pythagorean relationship as;

13²-5²=b²

144 = b²

√144 = b

12 = b

Opposite side length = 12

Sin ∅ = opposite side length / hypotenuse

Sin ∅ = 12/13

A25f oz. botie of Tide detergent costs $3.99 and a 90 fl oz. bottle of Tide detergent costs $6.99. Is the 25 oz or 90 oz bottle of Tide a better

buy?

Answers

Answer:

The 90 oz bottle of Tide is the better buy because it has a lower price per oz.

Step-by-step explanation:

To find the bottle of Tide that is a better buy, you have to divide each price for the number of ounces they have and determine the one that has the lower price per ounce.

$3.99/25= $0.15

$6.99/90= $0.07

According to this, the answer is that the 90 oz bottle of Tide is the better buy because it has a lower price per oz.

Answer: The correct option is the second one, counting from the top.

Step-by-step explanation:

For a rectangle of length L, and width W, the area can be calculated as:

A = L*W

In this case, we know that:

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

and

[tex]W = \sqrt[3]{x^2}[/tex]

First, we need to remember the relations;

[tex]\sqrt[n]{x^m} = x^{m/n}[/tex]

[tex]x^m*x^n = x^{m + n}[/tex]

[tex]\frac{x^n}{x^m} = x^{n - m}[/tex]

a) Now we can calculate the area of the rectangle as:

[tex]A = L*W = \sqrt{x} *\sqrt[3]{x^2} = (x^{1/2})*(x^{2/3}) = x^{1/2 + 2/3} = x^{3/6 + 4/6} = x^{1/6 + 1}[/tex]

And we can write that last part as:

[tex]x^{1/6 + 1} = x*x^{1/6} = x*\sqrt[6]{x}[/tex]

b) Now we want to find the ratio between the width and the length:

[tex]\frac{W}{L} = \frac{\sqrt[3]{x^2} }{\sqrt{x} } = \frac{x^{2/3}}{x^{1/2}} = x^{2/3 - 1/2} = x^{4/6 - 3/6} = x^{1/6} = \sqrt[6]{x}[/tex]

Now, if x = 1, the ratio will be equal to 1.

if x > 1, the ratio will be larger than 1.

if  0 < x < 1, the ratio will be smaller than 1.

The head circumference C of a child is related to the height H of the child (both in inches) through the function H (C) = 2.15C - 10.53.
Find the inverse function, and use the inverse function to predict the head circumference of a child who is 26 inches tall. (1 point)

Answers

Answer:

The inverse function is C (H) = H+10.53/2.15. The approximate head circumference of a child who is 26 inches tall is 16.99 inches.

Step-by-step explanation:

Using the inverse function, the head circumference of a child who is 26 inches tall is;

16.99 inches

We are given the function;

H(C) = 2.15C - 10.53

Where;

H s height of the child

C is head circumference of a child the

To get the inverse of the function, we will make C the subject to get;

C(H) = (H + 10.53)/2.15

At H = 26 inches, we have;

C(26) = (26 + 10.53)/2.15

C(26) = 16.99 inches

A linear function plot is shown below. The plot represents a function of the form Y = mX + b where m represents the slope of the plot line and b represents the intercept. Determine m and b from the plot. If X = –3.5, calculate the value of Y and enter it in the box with one digit to the right of the decimal point.

Answers

-10 is the answer :)

A linear plot is used to represent straight line equations. From the plot, we have the following:

The slope (m) is -2The intercept (b) is 3The value of y when [tex]x = -3.5[/tex] is 10

From the plot (see attachment), we have the following coordinate points

[tex](x_1,y_1) = (1,1)[/tex]

[tex](x_2,y_2) = (2,-1)[/tex]

The slope (m) is calculated using:

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

So, we have:

[tex]m = \frac{-1-1}{2-1}[/tex]

[tex]m = \frac{-2}{1}[/tex]

[tex]m = -2[/tex]

The intercept (b) is the point where the line crosses the y-axis.

From the attached plot, the graph crosses the y-axis at [tex]y = 3[/tex]

This means that:

[tex]b = 3[/tex]

So, the equation [tex]y = mx + b[/tex] is:

[tex]y = -2x + 3[/tex]

The value of y when [tex]x = -3.5[/tex] is:

[tex]y = -2\times -3.5 + 3[/tex]

[tex]y = 7 + 3[/tex]

[tex]y = 10[/tex]

Hence:

The slope (m) is -2The intercept (b) is 3The value of y when [tex]x = -3.5[/tex] is 10
