f(x) = 3x ^ 2 + 2x + 10

Answers

Answer 1

Answer:

No x-intercept (zero)

f(0)=10

Step-by-step explanation:

Answer 2
No x- intercept/Zero

Step-by-step
F(x) = 3x^2 + 2x + 10
To find x-intercept/zero, Substitute
F(x) = 0
0 = 3x^2 + 2x + 10
Swap the side of the equation
3x^2 + 2x + 10 = 0
Solve the quadratic equation
ax^2 +b+c = 0
X= -b+ b^2 -4 a c/ 2a
X= -2+ 2^2 -4 x 3 x 10/2x3
X= -2+ 4-4 x 3 x 10/ 2 x 3
-> x=-2+ 4-120/2 x 3 -> x=-2 4-120/6
X=-2+ -116/6
-> calculate the difference
X= -2+ -116/6
The square root of a negative
number dose not exit in the set of
Real numbers
No x-intercept/zero

“An elephant charged 13.3 meters in 15 seconds.
At this rate, how far would the elephant move if it
could charge for 1 minute?”

Answers

Answer:

53.2 meters

Step-by-step explanation:

If an elephant charged 13.3 meters in 15 seconds, to calculate the distance charged by the elephant in one minute, the following steps will be arried out.

15 seconds = 13.3 meters

1minute (60 seconds) = x

cross multiply

15 * x = 13.3 * 60

15x = 798

Divide both sides by 15

15x/15 = 798/15

x = 53.2metres

Hence the elephant will charge 53.2 meters for 1 minute

A restaurant manager states the number of customers that enter the
restaurant is equal to 3 times the number of people that buy a hotdog from
the hotdog cart plus 15.
The manager also states that the number of customers that enter their
restaurant is equal to 2 times the number of people that buy a hotdog from
the hotdog cart plus 60.
What number of people buying a hotdog from the hotdog cart across the
street makes the equation 3x +15 = 2x +60 true?

Answers

Yes it is true because if 3x +15=2x+60 it is true

Answer:

Yes, that is true, and x=45.

Step-by-step explanation:

Yes, that's how you set up the equation I also listed the sets to solve it below:

3x+15=2x+60

-2x.     -2x

--------------------

x+15=60

  -15 -15

------------------

x=45

You can also plug it in to check your work.

3(45)+15=2(45)+60

135+15=90+60

150=150

Step-by-step explanation:

So we want to find the value of x.

Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:

[tex]JK=JI+IK[/tex]

We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:

[tex]2x-1=(2)+(x+3)[/tex]

On the right, add:

[tex]2x-1=x+5[/tex]

Add 1 to both sides:

[tex]2x=x+6[/tex]

Subtract x from both sides. The right cancels:

[tex]x=6[/tex]

And the value of x is 6.

Our answer is B.
