Consider h(x)=x^2+8+15. identify its vertex and y-intercept.

OleMash [197]

Answer:

Vertex: (-4, -1)

Y-intercept: (0, 15)

Step-by-step explanation:

Given the quaratic function, h(x) = x² + 8x + 15:

In order to determine the vertex of the given function, we can use the formula, $[x = \frac{-b}{2a}, h(\frac{-b}{2a})]$ .

<h3>Use the equation: $[x = \frac{-b}{2a}, h(\frac{-b}{2a})]$ </h3>

In the quadratic function, h(x) = x² + 8x + 15, where:

a = 1, b = 8, and c = 15:

Substitute the given values for <em>a</em> and <em>b</em> into the equation to solve for the x-coordinate of the vertex.

$x = \frac{-b}{2a}$

$x = \frac{-8}{2(1)}$

x = -4

Subsitute the value of the x-coordinate into the given function to solve for the <u>y-coordinate of the vertex</u>:

h(x) = x² + 8x + 15

h(-4) = (-4)² + 8(-4) + 15

h(-4) = 16 - 32 + 15

h(-4) = -1

Therefore, the vertex of the given function is (-4, -1).

<h3>Solve for the Y-intercept:</h3>

The <u>y-intercept</u> is the point on the graph where it crosse the y-axis. In order to find the y-intercept of the function, set x = 0, and solve for the y-intercept:

h(x) = x² + 8x + 15

h(0) = (0)² + 8(0) + 15

h(0) = 0 + 0 + 15

h(0) = 15

Therefore, the y-intercept of the quadratic function is (0, 15).

Find X when x equals negative 15

Ann [662]

Judging by the question you have provided I came to the conclusion that you have already solved your own problem!

If the goal is to find X when X=-15 then your answer for X should be -15!

If this is not the entire equation please post the entire one!

Hope this helped!

A single, six-sided die is rolled. Find the probability of rolling an even number or a number less than 5.

Svetach [21]

The probability of rolling an odd number or a number less than 5 is 5/6.

Probability is the likelihood of the occurrence of an event. It is the ratio of number of events to number of possible outcomes.

The possible outcome from rolling a six-sided die is 1, 2, 3, 4, 5 and 6

P(odd number) = 3/6; P(less than 5) = 4/6; P(odd number and less than 5) = 2/6

Hence:

P(odd number or less than 5) = 3/6 + 4/6 - 2/6 = 5/6

The probability of rolling an odd number or a number less than 5 is 5/6.

30% of what number is 70

katrin2010 [14]

233 1/3

you start with .3x = 70, as this is the sentence given, solving for x.
divide both sides by .3, and you get x
