What Is The Length Of The Two Equal Sides?What Is The Length Of The Third Side?

Answers

Answer 1

Answer:

Two equal sides: 15 centimeters, Third side: 21 centimeters

Step-by-step explanation:

Sorry If I'm late, so how I solved this was by using variables and algebra. The perimeter of a triangle is the sum of all three sides. Let's now break down the problem and use the useful information, we know that the perimeter is 51 centimeters, and that there are two equal sides and the third side is 6 inches longer than the two equal sides. So it is pretty much an isosceles triangle since it has two sides of equal length and the third side is not equal to the others. So we can make an equation with variables. 51(Perimeter)=x(first equal side)+x(second equal side)+x(third side)+6(The third side is 6 centimeters longer than the two other sides), now we simplify the equation just like we do with most algebraic equations. x+x+x can be turned into 3x. This now makes the equation 51=3x+6, we can subtract 6 from both sides to just have the variable on one side, 3x+6-6, both sixes cross out making it 3x, 51-6 is equal to 45. Now we divide by three on both sides to give just x and find out what x is. 3x/3=x and 45/3=15. x=15, x is the equal side length, so the two equal sides are 15 centimeters and the third one is 21 centimeters. The reason for this is because 15+6=21. I hope this helped with your learning, if I am wrong please tell me :)

Find the time that that the projectile will reach a height of 96 ft and return to the ground when v0 = 112 feet per second

Answers

The time that the projectile will reach a height of 96 ft and return to the ground will be 6 seconds.

What is kinematics?

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

The projectile will reach a height of 96 ft and return to the ground when v₀ = 112 feet per second

The time it takes to reach feet and return to the ground will be

T = 2v₀  /  g

Where g = 32.2 feet per square second.

Then we have

T = 2 x 112 / 32.2

T = 5.956

T ≅ 6 seconds

3 4 5 is the first triangle most people encounter when they begin their study of the Pythagorean Theorem. You can show this to be true by trying it.

c = 5

b = 3

a = 4

c^2 = a^2 + b^2           Equation  Substitute values

c^2 = 3^2 + 4^2           Expand

c^2 = 9 + 16                 Combine

c^2 = 25                       Take the square root of both sides.

each day, what was the daily temperature change?
A. 36°F
B. -6°F
C. 6°F
D. -36°F

Answers

to find the daily change, let’s first find the total change
46 – 82 = -36 °F

we have 6 days, so divide
-36 / 6 = -36 °F per day

Answer:

B. -6

Step-by-step explanation:

You know immediately that it will be negative, because the temp is going down.

To find the exact answer, start by finding the difference between the two temps

82-46 = 36

since its a six day period, divide 36 by 6

36/6 = 6

so, the answer is -6

Answer:

1) (Un) is a geometric sequence.

2) Un+1 - Un ≤ 0.

3) (Un) is decreasing.

4) (Un) is convergent.

5) sum = 155

Step-by-step explanation:

Un+1 = 0.5Un

U₀ = 80

1) U is a geometric sequence (reason : Un+1 = 0.5Un).

2) Un+1 - Un = 0.5Un - Un = Un×(0.5 - 1) = -0.5Un ≤ 0 (because Un ≥ 0).

Remark: use Mathematical induction to prove that Un ≥ 0

3) Un+1 - Un  ≤ 0

then

Un+1 ≤ Un  

then

the sequence U is decreasing.

4) U is decreasing and Un ≥ 0

Then U is convergent.

5)  Since U is geometric sequence with first term U0 = 80 and common ratio = 0.5 .

Important: review the sum of consecutive terms of a geometric sequence.

Then

[tex]U_0+ U_1+ U_2+ U_3+ U_4=U_{0}\times \frac{1-\left( 0.5\right)^{5} }{1-0.5}=160\times(1-\left( 0.5\right)^{5} )=155[/tex]
