let me know

Answer:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Step-by-step explanation:

Hello!

Let's start with the given equation and work our way towards x.

Divide both sides by a

Move c/a to the other side

At the step, we have to use the Completing the Square method.

Multiply -c/a by 4a and add the two fractions

Square Root both sides

Subtract b/2a

And that's the derivation of the Quadratic Formula.

Answer: 2²/₃ cups of raisins.

Step-by-step explanation:

Question wants to know the number of cups needed for 4 batches of oatmeal bars.

Each batch needs 2/3 cups of raisins to make.

If there are 4 batches to be made therefore, one must multiple the 2/3 cups to make one batch by 4 to find out the number needed to make 4 batches.

= 2/3 * 4

= 8/3

= 2²/₃ cups of raisins.

Answer:

1

Step-by-step explanation:

7m+19/2=13

7m +19 = 13 x 2

7m = 26 - 19

m = 7/7 = 1

Another way :

7m+19/2=13

7m = 26/2 - 19/2

7m = 7

m = 7/7 = 1

Both ways r correct !!

I hope im right!!

Answer:

R=15 1/6

Step-by-step explanation:

You can add 5 and 1/6 to each side so -5 1/6+5 1/6= 0 so it cancels out therefore on the other side of the equal side you add 5 1/6+10 to get 15 1/6.

Answer:

r=25

Answer:

389.82 mi/hr

Step-by-step explanation:

For us to find the resultant speed of the aircraft, we will simply add the vector components of the wind and the vector velocity of the aircraft to get;

V = v_xi^ + v_yj^

Now,

v_xi^ = (300 + 100cos30°)i^

v_yj^ = (100 sin 30°) j^

This gives;

v_xi^ = 386.6 i^

v_yj^ = 50 j^

Thus;

V = 386.6 i^ + 50 j^

Resultant velocity is;

|V| = √(386.6² + 50²)

|V| = √151959.56

|V| = 389.82 mi/hr

Answer:

x = 0, y = -4

Now plug it in:

y = mx + b

-4 = b

So the y intercept is -4

You can also graph the equation.

Answer:

3

Step-by-step explanation:

Given the expression

cd + 3d2 – 2d

We are to determine the number of terms

From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3

Answer:

What are u rotating by

90/ or 180 degree

Answer:

42

Step-by-step explanation:

It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:

7a2-3ac+d2

7(2)(2) - 3(2)(-3) + (-2)(2)

28 + 18 - 4 = 42

Answer: x=45

Step-by-step explanation:

Solve for c get 20 c=b so b+115 =135  180-135=x

Answer:

x=45

Step-by-step explanation:

160=115+x (use vertical angles)

subtract 115 from both sides

160-115=45

x=45

Answer:

a is greater than -2

Step-by-step explanation:

Solving a comparison like this is the same as solving an equation, except you need to watch out for the signs of numbers.

Given:

-2a - 12 < -8

The first thing we need to do here is to add 12 to both sides:

-2a - 12 + 12 < -8 + 12

-2a < 4

You'll notice we're just increasing both sides, so the relationship stays the same.

Now we divide both sides by -2.  Because the number is negative, it changes whether the result is greater or less.

-2a < 4

-2a ÷ -2 > 4 ÷ -2

a > -2

Giving us our final answer.

Answer: THE ANSWER IS

Determine if the relation is a function.

The relation is a function.

Find the domain and range.

Domain:

{−3, −1,  5,  8}

Range:

{−6}

Graph.

{(−3,−6),  (−1,  −6),  (5,  −6),  (8,  −6)}

Determine if the relation is linear.

The relation is linear

Find the inverse.

( − 6 ,  − 3 ) ,   ( − 6 ,  − 1 ) ,   ( − 6 ,  5 ) ,   ( − 6 ,  8 )

Step-by-step explanation: IT'S NOT A OR D.. ig

1:    Recall that a function  from a set  to a set  is a relation that assigns to each element  in the set  exactly one element in the set . The set  is the domain (or set of inputs) of the function and the set  contains the range (or set of outputs).

The general characteristics of functions are:

A. Each element in A must be matched with an element in B.

B. Some elements in B may not be matched with any element in A.

C. Two or more elements in A may be matched with the same element in B.

D. An element in A (the domain) can not be matched with two different elements in B.

________________________________________________

Solving this problem we have:

1. The mapping diagram is represented in Figure 1. As you can see this is a function. Each element in A is matched with an element in B. All the elements in A are matched with the same element in B. So, this fulfills with the definition of function.

2. The mapping diagram is represented in Figure 2. This is not a function. Notice that an element in A (the domain) is matched with two different elements in B, that is, -8 is matched with -6 and 1.

2:    #1) This is a function.

#2) This is not a function.

(The mapping diagrams are not present to match to these.)

Explanation:

A function is a relation in which each element of the domain is matched to no more than one element of the range; in other words, no x gets mapped to more than 1 y.

In #1, no x is mapped to more than 1 y, so it is a function. However, in #2, -8 is mapped to both -6 and to 1; this x is used more than once, so this is not a function.

3:    what is the primary responsibility of the legislative branch

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

it represents new mexico in foreign affairs

4:    Answer:

Option D is correct.

The relation {(-8, -6) (-5, 2) (-8, 1) (7, 3)} is not a function.

Step-by-step explanation:

Given the relation:  {(-8, -6) (-5, 2) (-8, 1) (7, 3)}

Domain is the set of all possible inputs of a relation i.e { -8, -5 , -8 , 7}

Range is the set of output values of a function i.e, {-6, 2 , 1 , 3}

The mapping as shown below in the figure:

A function is a relation in which every element of the domain is matched to not more than one element of the range.

In other words, we can say that ,no value of x gets mapped to more than 1 value of y.

Since, from the mapping you can see that the domain value -8  paired with -6 and 1;  as x is used more than once.

Therefore, this relation is not a function

=============================================================

Explanation:

Define the following events

We are given the following probabilities

Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation

P(T given D) = 4/5

The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"

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

The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation

P(T given R) = 2/5

And also, the probability someone is on time if it is snowy is

P(T given S) = 1/10

due to it saying "If it snows, the probability that someone will arrive on time is 1/10".

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

To recap so far, your teacher told you these three conditional probabilities

They are conditional due to the "given" as part of the probability. They depend on the given event happening.

Subtract each fraction from 1 and we end up with these complementary probabilities

I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.

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

Recall the conditional probability formula is

P(A given B) = P(A and B)/P(B)

which rearranges to

P(A and B) = P(A given B)*P(B)

We'll use this idea to get the following

This means,

P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability

P(L) = 1/10 + 1/5 + 3/20

P(L) = 2/20 + 4/20 + 3/20

P(L) = (2+4+3)/20

P(L) = 9/20 is the probability someone is late
