Answer:

The zero product property states that if ab=0 , then either a=0 or b=0.

So when it comes to factors, you may have something that looks like this:

(x-1)(x+5)=0

With the property you can know that this means that you should set each factor to 0.

x-1=0 so x=1

x+5=0 so x=-5

This gives you the 2 x-intercepts of the equation 1 and -5

I hope this helped let me know if you need anything else!

A dozen box of bagels costs $4.98. Because of inflation the price increases by 4% a year.

Olenka [21]

A=p (1+r)^t
A future value
P present value 4.98
R rate 0.04
T time

After 3 years
A=4.98×(1+0.04)^(3)
A=5.60

7.50=4.98 (1.04)^t
Solve for t
T=log(7.50÷4.98)÷log(1.04)
T=10 years

Jason has $90 to spend. He wants to purchase a bag for $30, one eraser for $10, and three pencils. Each of the pencils costs the

snow_tiger [21]

90 = 30+10+3x

This equation shows that all the prices of the the bag, eraser, and pencils equals $90. So now all we have to do to find the price of a pencil is solve the equation.

First add the 30 and 10 together.

90 = 40+3x

Then subtract 40 from each side

50 = 3x

Lastly divide each side by 3

x = 16.67

The price per pencil is $16.67

Hope this helps!

P (a) =2/5 p(b)=1/4 ( a and b=1/25I did two events independent or dependent please help

juin [17]

we have

p (a) =2/5 p(b)=1/4 ( a and b=1/25

Remember that

we know that for two independent events A,B.

⇒ P(A∩B)=P(A)*P(B)

we have

P(A)=2/5 and P(B)=1/4

P(A∩B)=(2/5)*(1/4)=2/20=1/10

that means

<h2>events are dependent</h2>

Answer : 2√3

Given :-

A equilateral triangle with side length 4.

To Find :-

The value of x in the given figure.

As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .

So the perpendicular drawn in the figure will bisect the given side .
Therefore the value of each half will be 4/2 = 2 .

Now we may use Pythagoras theorem as ,

→ AB² = BC² + AC²

→ 4² = 2² + x²

→ 16 = 4 + x²

→ x² = 16-4

→ x² = 12

→ x =√12 = √{ 3 * 2²}

→ x = 2√3

Hence the required answer is 2√3 .

I hope this helps.
