y=x^2-8x+6 complete the square to determine the vertex and maximum or minimum value. Determine the number of x-intercepts.

Irina18 [472]

Answer:

Below in bold.

Step-by-step explanation:

y = x^2-8x+6

y = (x - 4)^2 - 16 + 6

y = (x - 4)^2 - 10

So the vertex is at (4, -10)

The coefficient of x^2 of this function is 1 ( positive) so there will be a minimum value.

Minimum value = -10.

x-intercepts:

(x - 4)^2 - 10 = 0

(x - 4)^2 = 10

x - 4 = +/- √10

x = 4 +/- √10

- therefore there are 2 x-intercepts.

Solve the equation. (enter your answers as a comma-separated list.)2^−125x = (0.5)^x − 5

ivolga24 [154]

2 - 125x = 0,5x - 5
-125x - 0,5x = -5 -2
-125,5x=-7
x= -7/-125,5
x=0,05...

Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70

-BARSIC- [3]

Answer:

The experimental probability of landing on heads is 0.3

Step-by-step explanation:

We are given the following in the question:

Number of heads = 30

Number of tails = 70

Talia said the probability of getting heads is $\frac{30}{70}$ .

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of heads =

$P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3$

The experimental probability of landing on heads is 0.3
