f(-3) = -1

We can find an unknown y-value by plugging an x-value into a given function.

Function Notation

Before we answer this question, we need to understand the notation of the equation. In function notation, the equation is given in terms of f(x).

For example, f(-3) represents the value of y when x = -3.

Finding f(3)

As stated above, to find f(-3) we need to plug -3 in for x. *Remember to use PEMDAS when solving.* This creates the new equation:

Then, distribute the exponent.

Next, multiply.

Distribute the negative.

Finally, add the remaining terms.

This means that when x = -3, y or f(-3) = -1.

The area and perimeter of the rectangle are 80 cm and 375 cm² respectively.

The rectangle is 15 cm wide.

The width is 3 / 5 of its length

Therefore, the area and the perimeter of the rectangle can be found as follows:

area of a rectangle = lw

where

Therefore,

w = 15 cm

15 = 3 / 5 × l

cross multiply

75 = 3l

l  =75 / 3

l = 25 cm

Therefore,

area of the rectangle = 25 × 15 = 375 cm²

Perimeter of the rectangle = 2l + 2w

Perimeter of the rectangle = 2(l + w)

Perimeter of the rectangle = 2(25 + 15)

Perimeter of the rectangle = 2(40)

Perimeter of the rectangle = 80 cm

Therefore, the area and perimeter of the rectangle are 80 cm and 375 cm² respectively.

The smallest integer is -3x.

The larger of the two integers is 18 and the smaller integer is 17.

Integers are collection of whole numbers and negative numbers. Integers are not fractional numbers or decimal. Some examples of integers are -5,-25,0,13,9 .

Let us consider the smaller integer be x.

As the integers are consecutive, the larger integer is (x+1).

Now according to the given condition:

Twice the large integer=2(x+1)

15 less than the 3 times the smaller integer=3x-15

Now the value of these two expressions is equal.

Therefore: [tex]2(x+1)=3x+-15[/tex]

Solving the above equation to find the value of x:

[tex]or,2(x+1)=3x-15\\or,2x+2=3x-15\\or,2x-3x=-15-2\\or,-x=-17\\or,x=17[/tex]

Therefore the smaller integer is 17.

Larger integer(x+1) : 17+1=18

Therefore the integers are 17 and 18.

Step-by-step explanation:

√750 = 27.3861278753

Answer:

False

Step-by-step explanation:

Sometimes, multiplication can occur after addition. For example, in 3+4*7, you don't add 3 and 4 first. You multiply 4 and 7 first since that's following the PEMDAS rule. After multiplying 4 and 7, then you add 3 to get a total of 31. ==> 3+4*7=3+28=31.

Probability= 5/9

Even cards = 2,4,6,8

Odd cards = 1,3,5,7,9

The number of ways of choosing one odd and one even number is 5C1 * 4C1

            (  5!/ 1!* 4!) * (4!/1! * 3!)

            5* 4= 20

Total number of ways of choosing 2 cards out of 9 = 9C2

        9!/ 2! * (9-2)!

[tex]y^{(4)} + y''' + y'' = 0[/tex]

Answer:

47 / 3 ( Or 1 if you typed it wrong)

Step-by-step explanation:

When simplifying an equation like this, we always want to do our multiplication and division before addition and subtraction.

So for the first step, let's simplify the expression down to only addition and subtraction...

12 - 2 / 6 + 4 =

12 - (2 / 6) + 4 =

12 - 1/3 + 4

Now we can combine everything together from left to right...

(12 - 1/3) + 4 =

35/3 + 4 =

47 / 3

However...

If the original equation was:

[tex]\frac{12-2}{6+4}[/tex]

Then you would just simplify the top and bottom separately before dividing the two numbers, treating the fraction as parentheses.

So...

(12 - 2) = 10

(6 + 4) = 10

And since 10 / 10 = 1

The answer to the fraction simplification is 1.

The solution of the expression would be 47/3.

Given that,

The expression is,

[tex]12 - \dfrac{2}{6} + 4[/tex]

Now simplify the expression by applying the BODMAS rule,

[tex]12 - \dfrac{2}{6} + 4[/tex]

[tex]12 - \dfrac{1}{3} + 4[/tex]

[tex]16 - \dfrac{1}{3}[/tex]

[tex]\dfrac{(48 - 1)}{3}[/tex]

[tex]\dfrac{47}{3}[/tex]

Therefore, the solution of the expression is 47/3.

The area of the region inside both curves r = 9 sin(θ) and r = 9 cos(θ) is 11.56 square units.

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

The curves are:

r = 9 sin(θ) and

r = 9 cos(θ)

On graphing the above curves:

From the graph:

A = (1/2)∫(9sin(θ))2dθ + (1/2)∫(9cos(θ)2dθ

The region is symmetrical about π/4,:

A = 81∫sin2(θ)dθ from 0 to π/4
