angle 3 = 57deg (alt. angles, //lines)

angle 2 = 180 - 57 - 33 = 90deg (angles in a triangle)

angle 1 = 180 - 90 - 57 = 33 deg (angles on a str line are supplementary)

If you like to venture further, feel free to check out my insta (learntionary). It would be best if you could give it a follow. I'll be constantly posting math tips and notes! Thanks!

The measures of angles 1, 2 and 3 are, 33, 90, 57 degree.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

from the given diagram,

angle 3 = 57deg (alt. angles, //lines)

angle 2 = 180 - 57 - 33 = 90deg (angles in a triangle)

angle 1 = 180 - 90 - 57 = 33 deg (angles on a str line are supplementary)

Answer:

Step-by-step explanation:

Given the function f(x)=-16x^2+100x+5 to calculate how far the potato will be from the ground at any given second (x), the potato hits the ground when g(x) = 0

The function becomes'

0 =-16x^2+100x+5

-16x^2+100x+5 = 0

multiply through by minus

16x^2-100x-5 = 0

x = 100 ±√100²-4(16(-5))/2(16)

x = 100±√10000+320/32

x = 100±101.59/32

x = 100+101.59/32

x = 202.59/32

x = 6.299 secs

Hence the potato will hit the ground after 6.299secs

The time taken by potato to hit the ground is [tex]6.299[/tex] seconds.

The potato will be from the ground at any given second (x) is given by below function.

             [tex]f(x)=-16x^2+100x+5[/tex]

To find the time taken by potato to hit the ground is , equate given function to zero.

            [tex]f(x)=-16x^2+100x+5=0\\\\-16x^2+100x+5=0\\\\x=\frac{-100\pm\sqrt{(100)^{2}+4*16*5 } }{-16*2} \\\\x=\frac{-100\pm101.587 } {-32} \\\\x=6.299,x=-0.049[/tex]

Since, time can not be negative.

So that we will consider , [tex]x=6.299 s[/tex]

Hence, the time taken by potato to hit the ground is [tex]6.299[/tex] seconds.

Answer:

Graph E, B, and D all show relations and are functions

Step-by-step explanation:

Graphs E, B, as well as D all represent functions and relations, respectively. A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X.

A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

A planet's position, for instance, depends on time. In the past, the idea was developed with both the infinitesimal calculus toward the conclusion of the seventeenth century, and the functions that were taken into consideration were differentiable until the 19th century. Graphs E, B, as well as D all represent functions and relations, respectively.

Therefore, graphs E, B, as well as D all represent functions and relations, respectively.

Answer: C(x) = (8 php)*x + 50 php.

Step-by-step explanation:

In a linear equation:

y = a*x + b

a is the slope.

x is the variable

b is the y-intercept.

In this case, we have

The rent is 50 php fixed, plus 8 php per hour.

Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.

then if we rent the bike for x hours, we will pay a plus of x*8 php.

Then the total cost for x hours, C(x), will be

C(x) = (8 php)*x + 50 php.

Then the slope is 8 php, and the y-intercept is 50 php.

The sum of 3 consecutive odd natural nos. can be represented by                      n +  ( n+2 ) + (n + 4 ).

Consecutive nos. are every no. after each other.

According to the given question we have to represent the sum of 3 consecutive odd natural nos.

We know that consecutive odd natural nos. come after every two digits.

∴ Assuming the first odd natural no. to be n.

So, Next odd natural no. will be (n + 2) and the third consecutive odd natural no. will be (n + 2) + 2 which is = (n + 4).

∴ The sum of 3 consecutive natural numbers can be represented by

n + (n + 2) + (n+4).

Step-by-step explanation:

The rule for triangle side lengths is that 2 sides gotta add up to be larger than the other. So ones like 40, 22, 14 wouldnt work since 22 and 14 only add up to 36. If u think about it, the lines wouldnt actually connect in real life.
