Given the binomials (x-1), (x-3), (x+3), (x+5), which one is the factor of f(x) = x^3 + 6x^2 + 12x +35?

Answers

The given polynomial is
f(x) = x³ + 6x² + 12x + 35

According to the Remainder Theorem, if x = a is a zero, then
f(a) = 0, and (x-a) is a factor.

Test (x-1):
f(1) = 1 + 6 +12 + 35 = 54   
Not a factor.

Test (x-3):
f(3) = 3³ +6*3² + 12*3 + 35 = 152
Not a factor.

Test (x+3):
f(-3) = (-3)³ + 6*(-3)² + 12*(-3) + 35 = 26
Not a factor.

Test (x+5):
(-5)³ + 6*(-5)² + 12*(-5) + 35 = 0
It is a factor.

Answer: (x+5) is a factor.

For what value of y does 125=(1/25)^y-1
A -5/2
B -2
C -1
D -1/2

Answers

The value of y that satisfies the equation is -1/2.

The correct option is D.

To solve the equation, using the property of exponents:

125 = (1/25[tex])^{y-1[/tex]

Now, 125 can be written in exponent form as (5³) and (1/25) as (5⁻²):

So, 5³ = (1/5²[tex])^{y-1[/tex]

5³ = (5⁻²[tex])^{y-1[/tex]

5³ =[tex]5^{-2y+2[/tex]

Since the bases are the same, comparing the exponents as:

3 = -2y+ 2

3-2 = -2y

-2y = 1

y= -1/2.

Therefore, the value of y that satisfies the equation is -1/2.

you can use similar triangles to find the height of a tree. Triangle ABC is similar to triangle DEC. what is the height of the tree?

please explain it too ^_^


Answers

So if triangle ABC is similiar to triangle DEC then we know that when two figures are similar, the ratios of the lengths of their corresponding sides are equal.So we can write:

AC/DC = BC/EC =AB/DE = k

BC= 9ft + 6ft = 15

BC/EC= k
15/6=k

Now that we know the k we can find the height of the tree that's equal to AB:

AB/DE= k
AB/4=15/6
6AB= 15 x 4
AB= 60/6 = 10

The height of the tree is 10ft


The height of the tree is 10 feet.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the ratios of the lengths of the corresponding sides are equal when two figures are similar, if triangle ABC and triangle DEC are similar, then we may write,

AC/DC = BC/EC = AB/DE = k

BC= 9ft + 6ft = 15

BC/EC= k

15/6=k

Now from this value of 'K' we can determine the height of the tree which is,

AB/DE = k

AB/4 = 15/6

6AB = 15 x 4

AB = 60/6 = 10

The height of the tree is 10ft.

A baker used 4 cups of flour to make 5 batches of brownies. He used_of a cup of flour to make 1 batch of brownies

Answers

(I dont know if this is the way your teacher told you how solve the problem but I'm gonna try it anyway)

First of all, Let x = the mystery amount of flour

To create my equation, I put cups of flour over the amount batches in a formation, kind of like a fraction. 

  cups
-----------  
batches 

Next, I fill in the values. 

 cups             4
-----------  = ---------  
batches        5

The 4/5 represents the first ratio of flour/batches. 

 cups             4               x
-----------  = ---------   = ---------
batches        5                1

Since we do not know that amount of flour it took to make one batch, we put x in it's place.

Now it's time to cross multiply. It's exactly like it sounds! Multiply diagonally. 

Multiply 5 and 'x'. Multiply 4 and 1. 

You end up with a eqaution that looks like:

5x = 4

As you would for any solve-by-x equation, divide the five on both sides. 

5x= 4
-       -
5     5

4/5 = Four-Fifths

5/5 cancels itself out and poofs into thin air. 

You end with x = 4/5

This is the answer. 

The baker used 4/5 cups of flour to make 1 batch of brownies :)

204 meters 89 cm = how many cm??

Answers

20,489 because 1 meter is 100 centimeters.

204 meters 89 centimeters is equal to 20,489 centimeters.

To convert 204 meters 89 centimeters to centimeters, we need to consider that 1 meter is equal to 100 centimeters.

204 meters is equal to 204 × 100 = 20,400 centimeters.

Adding the 89 centimeters, the total is 20,400 + 89 = 20,489 centimeters.

Therefore, 204 meters 89 centimeters is equal to 20,489 centimeters.
