Can someone help me find the area and perimeter please?

Lelu [443]

Answer:

Step-by-step explanation:

Remember that the formula to get the area of a right triangle is base times height divided by 2, so to find the area:

5 x 12 = 60/2 = 30

Area of this triangle is 30.

To find the perimeter, add all the sides:

5 + 12 + 13 = 30.

Perimeter of this triangle is 30.

Can someone please explain how to get this answer? Recursive formula help! t(1)=3 (in picture)

kipiarov [429]

T(1) = 3, t(n) = -2t(n-1) + 1
So t(2) = -2(t(1)) + 1 = -2(3) + 1 = -5
t(3) = -2(t(2)) +1 = -2(-5) +1 = 11
t(4) = -2(t(3)) +1 = -2(11) +1 = -21
t(5) = -2(t(4)) +1 = -2(-21) +1 = 43

The equation of a circle is given below. What is its center?

svp [43]

Answer:

$( \frac{2}{3}, 0)$

Step-by-step explanation:

The general equation for a circle is

${(x - a) }^{2} + {(y - b) }^{2} = {r}^{2}$

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0

Which of the following reveals the minimum value for the equation 2x^2 − 4x − 2 = 0?

12345 [234]

Answer:

$2(x-1)^{2}=4$

Step-by-step explanation:

The options of the question are

2(x − 1)2 = 4

2(x − 1)2 = −4

2(x − 2)2 = 4

2(x − 2)2 = −4

we have

$2x^{2} -4x-2=0$

This is a vertical parabola open upward

The vertex represent the minimum value

The quadratic equation in vertex form is

$y=a(x-h)^2+k$

where

a is a coefficient

(h,k) is the vertex

Convert the quadratic equation in vertex form

Factor 2 leading coefficient

$2(x^{2} -2x)-2=0$

Complete the squares

$2(x^{2} -2x+1)-2-2=0$

$2(x^{2} -2x+1)-4=0$

Rewrite as perfect squares

$2(x-1)^{2}-4=0$

The vertex is the point (1,-4)

Move the constant to the right side

$2(x-1)^{2}=4$
