Answer:  x = 6

Step-by-step explanation:

The perimeter of the isosceles triangle = 2 leg + base

Since the perimeter = 60

then 60 = 2(5x - 3) + x

       60 = 10x - 6 + x

 60 + 6 = 11x

         6 = x

Answer:

The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)

Step-by-step explanation:

Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.

(x,y) → (-x,-y)

Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).

The transformation (x,y) → (-x,-y) gives ;

(-1,1) → (1,-1)

(-2,6) → (2,-6)

(-5,4) → (5,-4)

Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".

Answer: 1/100 or 0.01

Answer:

At least 4 years

Step-by-step explanation:

Simple interest is given by

I = Prt

so here, one year's interest is

I = 300(.045) = 13.5

Divide 50 by 13.5 and get 3.7 years...thus

she will need four years to donate 50...

Step-by-step explanation:

Interest Rate = (Simple Interest × 100)/(Principal × Time).

given

Principal(P) = 300

Interest Rate(I.R) = 4.5%

Simple Interest(S.I) = 50

required

Time(T)

I.R = (S.I × 100)

(P ×T)

T × I.R = (S.I × 100) ×T

I.R (P × T) × I.R

T = (S.I × 100)

(P × I.R)

= (50 × 100)

(300 × 4.5)

= 5000

m<4 (exterior angle) = m<2+m<3( sum of two opposite interior angle)

hope this helps you.

The expression equivalent to m<4 when the given image is examined is m<2 + m<3.

According to mathematical theory, an exterior  angle is equal to the sum of the two interior opposite angles. An exterior angle is formed when a line extended from an adjacent side of a regular polygon. An interior angle is the angle that is formed inside the polygon.

Answer: your answer is correct because if you put that equation into y=mx+b form you get y=1/2x-1

so you start at -1 and go over 2 and up 1 and you woulld land on 2

Step-by-step explanation:

According to the graph, we see that our x-value stretches from x = -2 to infinity. Since x = -2 is a closed dot, it is included in the domain:

[-2, ∞) or -2 ≤ x < ∞

According to the graph, we see that our y-value stretches from y = -4 to infinity. Since y = -4 is a closed dot, it is included in the range:

[-4, ∞) or -4 ≤ y < ∞

Answer:

The answer is 84

Step-by-step explanation:

Step-by-step explanation:

(1 - cos²A)(1 + tan²A) = tan²A

1 + tan²A - cos²A - cos²A · tan²A = tan²A

1 + tan²A(1 - cos²A) - cos²A = tan²A

1 - cos²A + tan²A(sin²A) = tan²A

sin²A + tan²A(sin²A) = tan²A

sin²A (1 + tan²A) = tan²A

sin²A (sec²A) = tan²A

sin²A (1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → Proved

Answer: C

Step-by-step explanation:

We want to find the moon's gravitational acceleration.

With the given information, we will see that the gravitational acceleration on the moon is: g = 1.625 m/s^2

We know that in a place with a gravitation acceleration g, if you drop something from a height H, the position equation of that object will be given by:

p(t) = (-g/2)*t^2 + H

In this case, we know that a feather falls 81.25cm in one second.

First, we can define H = 0 (because we can put the zero of the position where we want to)

Then if after one second the feather falls 81.25cm = 0.8125 meters, we need to solve:

p(1s) = -0.8125 m = (-g/2)*(1s)^2

Where the negative sign comes because the feather "falls" and we define the negative position as below.

Also notice that we did a change of units from centimeters to meters, by knowing that:

100cm = 1m

then:

81.25cm = 0.8125m

Now we just need to solve:

-0.8125 m = (-g/2)*(1s)^2

0.8125 m = (g/2)*(1s)^2

2*0.8125 m = (g)*1s^2

1.625 m = g*1s^2

(1.625 m)/(1 s^2) = g

We then can conclude that the moon's gravitational acceleration is:

g = 1.625 m/s^2
