Mathematics
1 answer:
marishachu [46]2 years ago
4 0

Answer:

A.) = 6

If RE = 12, then RD = 6

B.) = 10

If BR = 10, then BE = 10

C.) = 16

If BD = 8, then BK = 16

D.) = 30*

<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*

E.) = 60*

If <m2 = 60*, then <m3 = 60*

F.) = 90*

It`s a 90* angle because BK and RE and perpendicular

G.) = 60*

If <m1 = 30*, then multiply by two because it is symmetrical

I would show all my work but you seem to be in a rush. Hope this helps!

The function f(x) = g(x), where f(x) = 2x – 5 and g(x) = x2 – 6.
den301095 [7]

Answer:

x=2.4

Step-by-step explanation:

<u>Solving Equations Using Successive Approximations</u>

We need to find the solution to the equation

f(x)=g(x)

where

f(x)=2x-5

g(x)=x^2-6

The approximation has been already started and reached a state for x=2.5 where

f(2.5)=0

g(2.5)=2.5^2-6=0.25

The difference between the results is 0.25, we need further steps to reach a good solution (to the nearest tenth)

Let's test for x=2.4

f(2.4)=-0.2

g(2.4)=2.4^2-6=-0.24

The new difference is -0.2+0.24=0.04

It's accurate enough, thus the solution is

\boxed{x=2.4}

How do I get the answer y= 2x^2+9x-5
guapka [62]

Answer:

Quadratic Formula

so

x = -5

and

x = 0.5

Step-by-step explanation:

Whenever you see a problem in this form, which you will see a lot of, you can try to factor it or use the "least squares" method or what have you, but those won't always work, unfortunately.

Fortunately, the quadratic formula will never fail you with quadratic expressions.

This is the Quadratic Formula

x = \frac{-b \frac{+}{-} \sqrt{b^2-4ac}  }{2a}

a is the the number on the variable with the exponent ^2

b is the number on the variable with no exponent

c is the third number

a and b cannot be equal to 0; c can be

Since we're looking for a number with an equation that has a square root in it, we're going to get two answers. These two answers come from the radical being separately added AND subtracted from the radical. It's basically two problems.

Plugging  in our numbers to this equation gives us x values of -5 and 0.5. This will always work with polynomials with factors of ^2 in them.

If you have a TI-84 calculator or newer, there's a tool on it that will factor polynomials like this one for you just by giving it the numbers.
