I know the answer just need someone explain to me how to solve it

Answer:

Part A: f(4) = 2

Part B: k = -7

Step-by-step explanation:

f(4) simply means what the y-value of the graph is when x = 4.

The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.

Part B asks to solve the equation: f(4) + k = -5

We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):

2 + k = - 5

Substract 2 from both sides:

k = -7

Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

Answer:

Area: 16.65m^2 (^2 means to the power of 2 exponent, or squared)

Perimeter: 26.3 m

Step-by-step explanation:

Triangle Area formula: bh/2

Plug it in: (7.4)(4.5)/2=16.65

Perimeter: Add the sides

12.6+7.4+6.3=26.3

Answer:

Step-by-step explanation:

Remark

Here are the formulas for what you are asking for.

P = s1 + s2 + s3

Area = height * base / 2

Givens

s1 = 12.6

s2 = 6.3

s3 = 7.4

height = 4.5

base = 7.4

The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended.  See the givens for what that is.

Solution

Perimeter

P = s1 + s2 + s3                        Substitute givens into the formula

P = 12.6+6.3 + 7.4

p = 26.3

Area

Area = (B * H)/ 2

Area = 7.4 *4.5 / 2

Area = 16.65

a= c/√2

b= c/√2

Since side a and b are equivalent to each other and c is the length of side a or b × √2. Dividing c by √2 gives the value of a and b.

a×√2= c

b×√2= c

Step-by-step explanation:

I hope you understand.....

A customer is more likely to have 1 pet and no children than they are to have 2 pets and no children.

We are given a table with 3 columns titled "have children", "do not have children" and "total".

Under the row titled "1 pet", the respective probabilities are;

P(having 1 pet and children) = 38/91 =  0.4176

P(having 1 pet and no children) = 53/91 = 0.5824

Under the row titled "2 pets", the respective probabilities are;

P(having 2 pets and children) = 85/126 = 0.6746

P(having 2 pets and no children) = 41/126 = 0.3254

Under the row titled "3 or more pets", the respective probabilities are;

P(having 3 or more pets and children) = 46/118 = 0.3898

P(having 3 or more pets and no children) = 72/118 = 0.6102

The only probability that is lower than P(having 1 pet and no children) in the same way is P(having 2 pets and no children).

Answer:

105

Step-by-step explanation:

First, in problems like these, you have to find 30% of 150. 30% of 150 is 45. Now, since you want to see how many pies have been sold, you do 150-45, which will give you 105.

Answer:

Cameron's age=48         Christain's age=54

Step-by-step explanation:

The current total age is 102.

You can do 102-6 as this will give you an idea of Christain's age as it is twice the age of Cameron.

102-6=96

96/2=48

Cameron's age=48

102-48=54

54=Christain's age
