Answer 1

Answer:

C

Step-by-step explanation:

so we are given our equation in point-slope form; y-y1=m(x-x1). (x1,y1) is a point, where m is the slope.

Perpendicular lines have slopes that are negative and reciprocal; when you multiply them, they are equal to -1.

The slope of our line is 2.

To find the slope of the new line, use this equation:

2m=-1

divide by 2

m=-1/2

so the slope of our new line is -1/2

as said above, slope-point form is y-y1=m(x-x1)

we are given the point (-3,-5)

substitute our info into the equation:

y--5=-1/2(x--3)

or:

y+5= -1/2(x+3)

the answer is C

Hope this helps!

What is the greatest number of soda cans that can fit inside of a box 15 in. high, 8 in. wide and 23 in. long?

Answers

Answer:

117 soda cans

Step-by-step explanation:

First find the volume of the soda can and box.

box V= l * w * h

box V= 15* 8 * 23

box V= 2,760 in²

can V= πr²h

can V= π(2.5/2)²*4.8

can V= 23.56

box V/ can V

2,760/23.56 = 117.15

you can only round down so 117 cans

The answer is 117 soda cans.

explain how 7/10 and 70/100 are equivalent decimals

Answers

Step-by-step explanation:

7/10 in percentage form is 70%

70/100 in percentage form is 70%

Simple as that

It is proved that the given decimals are equivalent decimals.

What are equivalent fractions? What is a mathematical function, equation and expression?equivalent fractions : Equivalent fractions can be defined as fractions that may have different numerators and denominators but they represent the same value.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given are the fractions -

7/10 and 70/100

We have the following fractions -

A = (7/10) = 0.7

B = 70/100 = (7 x 10)/(10 x 10) = (7/10)

B = (7/10) = 0.7

It can be seen that fraction A equals to B.

Therefore, it is proved that the given decimals are equivalent decimals.

Write a paragraph that addresses the question: How do I apply my knowledge of angles to find missing measurements?

Answers

Answer:

I won't write it in paragraph but use this:

angle A + angle B + angle C = 180 so when one angle is missing add the other 2 and subtract it to 180, that would be the answer for the missing angle; applies only to triangle (all kinds)if its the exterior angle, add them all like the one above but subtract it instead to any shapes or if it is adjacent to a given degree, you can always subtract it to 180 to get the exteriorif its a different shape, count the sides and subtract it by two then multiply by 180; thats the degree for the total angles of the shapeif its variable, do the third one (unless you know what it is) add them all like the first one and subtract to the answer in the #3

A bicycle has a listed price of $577.98 before tax. If the sales tax rate is 6.5%, find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

$615.54

Step-by-step explanation:

Step 1

Write your problem.

577.98 x 6.5% = ?

Step 2

Convert the % to a decimal:

6.5% to 0.065

Step 3

Rewrite the problem with decimal replacing the percentage.

Now the problem looks like this:

577.98 x 0.065 = 37.56

This problem gives the amount of the tax.

Step 4

Add the original price with the tax amount:

577.98 + 37.56 = $615.54 (total cost)

Find the maximum rate of change off at the given point and the direction in which it occurs.

f(x, y) = 4y √x, (4, 1)

Answers

Answer:

Maximum rate change |[tex]\nabla[/tex]f| = √65

Direction = ( 1, 8 ) / √65

i.e Maximum rate change is √65 and it occurs in a direction of ( 1, 8 )

Step-by-step explanation:

Given that;

f(x, y) = 4y √x, (4, 1)

{ x=4 and y=1 }

Maximum rate of change occurs with the gradient vector;

[tex]\nabla[/tex]f = [ df/dx, df/dy ] = [ 2y/√x, 4√x ]

we substitute in our value of x and y

[tex]\nabla[/tex]f =  2(1)/√4, 4√4

[tex]\nabla[/tex]f = 2/√4, 4√4

[tex]\nabla[/tex]f = ( 1, 8 )

Maximum rate change |[tex]\nabla[/tex]f| = | ( 1, 8 ) | = √( 1² + 8² ) = √(1 + 64)

Maximum rate change |[tex]\nabla[/tex]f| = √65

Direction = [tex]\nabla[/tex]f / |[tex]\nabla[/tex]f|

we substitute

Direction = ( 1, 8 ) / √65

i.e Maximum rate change is √65 and it occurs in a direction of ( 1, 8 )

Step-by-step explanation:

Find the coordinates of the point where the lines with equations y=x and y=-6 intersect.

The lines intersect at y = y

Equating the right hand side of both expressions we have;

x  = -6

Since y = x, hence y = -6

The required coordinate where they intersect is at (-6, -6)
