Find the distance from point $a\left(-1,\ 7\right)$ to the line $y=3x$. Round your answer to the nearest tenth. The distance is about units.

Answers

Answer 1

The distance from point [tex]$a\left(-1,\ 7\right)$[/tex] to the line [tex]$y=3x$[/tex] is about 4.5 units, rounded to the  nearest tenth.

The distance from point [tex]$a\left(-1,\ 7\right)$[/tex] to the line [tex]$y=3x$[/tex] is equal to the length of the perpendicular line from point [tex]$a$[/tex] to the line[tex]$y=3x$[/tex]. The formula to find the distance from a point [tex]($x_1, y_1$)[/tex] to a line [tex]$ax+by+c=0$[/tex] is given by:

[tex]$$\frac{|ax_1+by_1+c|}{\sqrt{a^2+b^2}}.$$[/tex]

Substituting[tex]$$\frac{|ax_1+by_1+c|}[/tex] into the formula, we get:

[tex]$$\frac{|-3(-1)+1(7)+0|}{\sqrt{3^2+1^2}} = \frac{20}{\sqrt{10}}.$$[/tex]

Therefore, the distance from point [tex]$a\left(-1,\ 7\right)$[/tex] to the line [tex]$y=3x$[/tex] is about 4.5 units, rounded to the nearest tenth

what is the area of a square with an apothem length of 14 inches?

Answers

Answer:

784

Step-by-step explanation:

A = 1/2ap       A = area , a = apothem , p = perimeter  

a = 1/2s          a = apothem length , s = side length

14 = 1/2s , 14(2) = 1/2s(2) , 28 = s

p = 4(s) , p = 4(28) , p = 112

A = 1/2ap , A = 1/2(14)(112) , A = 784

                 or

A = s^2 , A = 28^2 , A = 784

The area of a square with an apothem length of 14 inches is 784 inches.

What is apothem?

The perpendicular from the center of a regular polygon to one of the sides.

As, A = 1/2*a*p      

where, A = area , a = apothem , p = perimeter  

Also, a = 1/2s          

where, a = apothem length , s = side length

14 = 1/2s

14*2=s

s=28 inches.

Now, perimeter of square

p = 4(s)

p = 4(28)

p = 112 inches

Now, Area of square,

A = 1/2ap

A = 1/2*(14)*(112)

A = 784 inches

Hence, the area of square is 784 inches.

Let t = maximum daily sugar value

From the question, we know that : 92% of the daily value is 46 grams

this equation can be formed

0.92 x t = 46 grams

to find t, divide both sides of the equation by 0.92

If p(x) = 5(x^2 +1) + 16, what is the value of p(11)?
A. 622
B. 736
C. 626
D. 690​

Answers

C. p(11) = 626.

Step-by-step explanation:

Given  : p(x) = 5(x²+1)+16.

To find :  what is the value of p(11).

Solution : We have given  p(x) = 5(x²+1)+16.

For x = 11.

p(11) = 5((11)²+1)+16.

p(11) = 5 ( 121 + 1 ) +16.

p(11) = 5 (122) + 16.

p(11) =  610 + 16.

p(11) = 626.

Therefore,  p(11) = 626.

Answers

Answer: 3.32276 units squared

Step-by-step explanation:

area of total sector=(pi*r^2)/360

=2^2 * 120pi /360

=4*120/360 * pi

=4.1887902

area of the triangle=(1/2)*base*height

the height is 1 (because you can divide the triangle down the middle to make a 30 60 90 triangle, and the sin(30)=x/2, so 2sin(30)=x, x=(1/2)*2

the base is equal to [tex]\sqrt{3}[/tex] because the base of the 30 60 90 triangle is 2sin(60), and sin60 is [tex]\sqrt{3}[/tex]/2, so you have to double that to get the area of the 120 degree triangle.

the area of the triangle is (1/2)*1*[tex]\sqrt{3}[/tex]=[tex]\sqrt{3} /2[/tex]=0.866025

so the difference is 4.1887902-0.866025
