Answer:

The answer to this question is given below in the explanation section

Step-by-step explanation:

This is a simple division question.

In division there are some terms used that are:

Dividend: The number which we divide is called a dividend. In this case, 425 is a dividend

Divisor: The number by which we divide is called the divisor. In our question, it is 15.

Quotient: The result obtained is called the quotient.

Remainder: The number left over is called the remainder.

So the answer to this question is:

452/15= 30.133

so the answer is 30.1333

Answer:

Is there a picture to go with the question??

Step-by-step explanation:

Answer:

what we are trying to prove

Step-by-step explanation:

Given:

The function is

[tex]f(x)=x^3-3x^2+5x-15[/tex]

To find:

The root of the function from the given possible roots.

Solution:

We have,

[tex]f(x)=x^3-3x^2+5x-15[/tex]

At x=-3,

[tex]f(-3)=(-3)^3-3(-3)^2+5(-3)-15[/tex]

[tex]f(-3)=-27-27-15-15[/tex]

[tex]f(-3)=-84\neq 0[/tex]

At x=-1,

[tex]f(-1)=(-1)^3-3(-1)^2+5(-1)-15[/tex]

[tex]f(-1)=-1-3-5-15[/tex]

[tex]f(-1)=-24\neq 0[/tex]

At x=1,

[tex]f(1)=(1)^3-3(1)^2+5(1)-15[/tex]

[tex]f(1)=1-3+5-15[/tex]

[tex]f(1)=-12\neq 0[/tex]

At x=3,

[tex]f(3)=(3)^3-3(3)^2+5(3)-15[/tex]

[tex]f(3)=27-27+15-15[/tex]

[tex]f(3)=0[/tex]

Since, the value of given function is 0 at only x=3, therefore 3 is a root of given function.

Hence, the correct option is D.

Perimeter of a rectangular plot = 36 m.

length of the plot

Let the length of the plot be x and it's breadth be y.

We know that,

Perimeter of a rectangle = 2(length + breadth)

⟹ 2(x + y) = 36

⟹ x + y = 36/2

⟹ x = 18 - y -- equation (1)

Also,

If length is increased by 6 m & breadth is decreased by 3 m , the area remains same.

Area of a rectangle = length * breadth

So,

(x + 6) * (y - 3) = xy

⟹ x(y - 3) + 6(y - 3) = xy

⟹ xy - 3x + 6y - 18 = xy

Substitute the value of x from equation (1).

⟹ - 3(18 - y) + 6y = 18

⟹ - 54 + 3y + 6y = 18

⟹ 9y = 18 + 54

⟹ y = 72/9

⟹ y = 8 m

Substitute the value of y in equation (1).

⟹ x = 18 - 8

⟹ x = 10 m

Hence,

Length (x) = 10 m

Breadth (y) = 8 m.

∴ The length of the plot is 10 m.

I hope it will help you.

Regards.

b is the intercept

Step-by-step explanation:

BRAINLIEST please? sorry caps lol

Answer:

The answer is "p=25.63 and h= 6.24".

Step-by-step explanation:

p = cost of the plain

h = cost of the holiday

[tex]\to 10p + 7h = 330.........(i)\\\\\to 4p + 14h = 356........(ii)[/tex]

multiply by 2 in equation (i) and subtract from the equation (ii):

[tex]\to 20p + 14h = 660\\\\\to 9p + 14h = 378\\\\subtract\\\to 11 \ p =\ 282 \\\\\to p = \frac{282}{11}\\\\\to p = \$ \ 25.63[/tex]

put the value of p in equation (i):

[tex]\to 10(25.63)+7h=330\\\\\to 256.3+7h=330\\\\\to 7h=330 - 256.3\\\\\to 7h=330 - 256.3\\\\\to 7h= 43.7\\\\\to h= \frac{43.7}{7}\\\\\to h=6.24[/tex]

Answer: Yes

Step-by-step explanation: You can determine if a graph is a function with the vertical line test. If you drew a vertical line anywhere through this graph it would intersect the graph no more than once.

Answer:

119 degrees

Step-by-step explanation:

We know that a full straight line is 180 degrees. This angle is 61 degrees, so we subtract 61 from 180.

180 - 61 = 119 degrees

I hope this helped, please mark Brainliest, thank you!

Answer:

119

Step-by-step explanation:

a line equals 180 degrees, so just subtract 61 from 180

Answer:

looks proportional to me

Step-by-step explanation:

Answer:

Proportional

Step-by-step explanation:

Direct proportion:

y = kx

1*4 = 4

2*4 = 8

3*4 = 12

Given values in the table satisfy the equation of direct proportion. So, it is a direct proportion.

Answer:

list 3

Step-by-step explanation:

if you look at list 3 "4.5 feet, 4.25 feet, 4 feet, 3.99 feet, 3.5 feet" you can easily see that it is going from greatest to smallest because 4.5 is larger than 4.25 and 4.25 is larger than 4 and 4 is larger that 3.99 by 0.01 as you see its only 0.01 diffrence but it is still larger

Answer:

List 3

Step-by-step explanation:

I got it right (;

Answer:

y=-1/4x+3

Step-by-step explanation:

put it into y-y1=m(x-x1) form, which gives you y+3=-1/4x(x+0)

(side note: we change the y- to a y+ becuase the y in the point in negative. another side note, the slope is -1/4x because perpendicular slopes are opposite, in this case 4x (or 4/1x) is the opposite of -1/4 x)

then remove the parenthesis. y+3=-1/4x

then isolate y and balance the equation.

y+3-3=-1/4x-3

this gives you the answer of y=-1/4x-3.

Answer:

y=-2x-3

Step-by-step explanation:

The equation of the line in the slope-intercept form is y=x2−2.  

The slope of the perpendicular line is negative inverse: m=−2.

So, the equation of the perpendicular line is y=−2x+a.

To find a, we use the fact that the line should pass through the given point: −3=(−2)⋅(0)+a.

Thus, a=−3.

Therefore, the equation of the line is y=−2x−3.

Answer: y=−2x−3.

Answer: -2

Explanation: The -2 is called the x-coordinate

or horizontal move from the origin.

All points are written in the form (x, y).
