X and 67° are supplementary (they equal 180) so to find x you do 180-67 which equals 113. So x=113°

Since 67 and y are vertical angles then y is 67

Write an equation for each exponential function in the form y=abₓ (to the xth power)

GuDViN [60]

Answer:

y = 2 * 9 ^ x

Step-by-step explanation:

From the first point, you can get the value of a, since any number with power 0 with always equal to 1

2 = a(1)
a = 2

Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.

1458 = 2b ^ 3
729 = b ^ 3
B = 9

Can someone help me understand how to do this quadratic math problem

Juliette [100K]

Answer:

put all of the expressions into the same form, such as standard form

Step-by-step explanation:

When you're trying to determine whether one expression is equivalent to another, you need to put both of the expressions into the same form. This will generally require some algebraic manipulation using the rules of equality.

Here, you're given a quadratic in standard form. From what we can see of the one partial answer, some of the choices are in vertex form. To determine if they are equivalent, you can do either of two things ...

Put the given expression into vertex form
Expand the answer choice to put it in standard form

___

<em>For multiple-choice questions</em> of this type, it is often sufficient to look at one or two terms of the different equations. That is usually all it takes to separate a good answer from a bad one.

You can start with the x^2 term. Any answer choice that has an x^2 coefficient different from 1 will be rejected.

Next, you can look at the sign of the x term. Any answer choice that doesn't have a positive x term will be rejected.

Finally, you can look a the constant term. Any answer choice that doesn't have a constant term of +4 will be rejected.

___

As it happens, the given equation is a perfect square, so one equivalent is ...

y = (x +2)^2

_____

When working with quadratics, it can be helpful to memorize a couple of the ways they can be written:

(x +b)^2 = (x^2 +2bx + b^2)

This is a special case of ...

(x +a)(x +b) = x^2 +(a+b)x + ab

When two standard dice are thrown, what is the probability that the sum of the dots on the two top faces will be 3? Express your

Neko [114]

Answer:

0.056 = 5.56% probability that the sum of the dots on the two top faces will be 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have these possible outcomes:

Format(Top face A, Top face B)

(1,1), (1,2), (1,3), (1,4), (1,5),(1,6)

(2,1), (2,2), (2,3), (2,4), (2,5),(2,6)

(3,1), (3,2), (3,3), (3,4), (3,5),(3,6)

(4,1), (4,2), (4,3), (4,4), (4,5),(4,6)

(5,1), (5,2), (5,3), (5,4), (5,5),(5,6)

(6,1), (6,2), (6,3), (6,4), (6,5),(6,6)

There are 36 possible outcomes.

Desired outcomes:

Outcomes in which the sum of the dots on the top two faces will be 3.

(1,2)

(2,1)

Two possible outcomes.

Probability:

2/36 = 0.056 = 5.56% probability that the sum of the dots on the two top faces will be 3
