Answer:

  (c)  Exponential

Step-by-step explanation:

The independent variable in the equation is in the exponent, so this is an exponential equation.

Additional comment

Linear and quadratic equations are specific cases of polynomial equations, which involve sums of powers of the variables. The highest power involved is the degree of the equation: 1 for linear, 2 for quadratic.

  f(x) = x +2 . . . . has x to degree 1, so is a linear equation

  f(x) = 3x^2 -5 . . . . has x to degree 2, so is a quadratic equation

  f(x) = √(x -6) . . . . is "none of these"

(This is another vocabulary question. Linear, quadratic, exponential, degree, term, polynomial, ... are all words with specific definitions related to algebraic functions.)

Answer:

13 x 3 ft

Step-by-step explanation:

RECTANGULAR deck

L x W = 39 ft^2

(w+10)  x w = 39

w^2 + 10w - 39 = 0

(w-3)(w+13) = 0        w = 3    or  -13 (throw out)

w = 3    then l = 10 +3 = 13

Answer:

"=" and "<"

Step-by-step explanation:

|9| = |-9|

|9| and |-9| indicates the absolute value of 9 so we use equality sign

7.5 = 7.50

7.5 is equal to 7.50 adding zeros to the right side of an expression won't change its quantity

For example:

I say I have 7.5 dollars and my friend says he has 7 dollars and 50 cent

We have same amount of money.

-3.31 is smaller than -3.13 because it's further from point zero in number line so we use < for this expressions.

Answer:

Yes, it is in the tenth place, and it is 5 thousand is 10,000 times more than the 5 in the tenth place

Step-by-step explanation:

3 = ones place

.5 = tenths place

.04 = hundredths place

.005 = thousandth place

for the second question all you need to do it

5000 divided by .5 = 10000 (because they both have 5, don't try this if there are :example: 4 in the hundreds place to 3 in the one's place).

Answer:

The value of the 5 in the tenths place of 3.545 is 10 times the value of the 5 in the thousandths place

Answer:

2x^3 + 5x^2 - 18x - 45 m

V = lwh

V = (x + 3)(x - 3)(2x + 5)

V = ((x)(x) + (x)(-3) + (3)(x) + (3)(-3))(2x + 5)

V = (x^2 - 3x + 3x - 9)(2x + 5)

V = (x^2 - 9)(2x + 5)

V = (x^2)(2x) + (x^2)(5) + (-9)(2x) + (-9)(5)

V = 2x^3 + 5x^2 - 18x - 45

An exponential function follows the form a^x, where a is a constant. Other answers incorrectly say it depend on the exponent but that is no true because this is a constant raised to x NOT x raised to a number.

You ask for rate of change in other words derivative

You may recall that the derivative of a^x is a^x*ln(a).

The standard deviation statistic should use to measure the spread of the two sets of data.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

As we know, the shape of a normal curve is dictated by its mean and standard deviation, hence standard deviations are important.

Thus, the standard deviation statistic should use to measure the spread of the two sets of data of snowfall which is collected by the scientist.

Answer:

R' (- 1, 6 )

Step-by-step explanation:

under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

R (- 1, - 6 ) → R' (- 1, 6 )

Answer:

the answer should be (-1, -6) because remember when you are doing these kind of problems of pluging in the points in a coordinate plane remember the quadraunts  to help you know everything you need in case of future problems.

So back remember first is x and then y so when we analyze the point the x is -1 and the y is -6 so the point r represnts= (-1,-6)

so hopefully that is the correct answer and have a great day.

remember first is x and then y

Answer:

h = 20.5 yards

Step-by-step explanation:

Volume of Rectangular Pyramid: lwh/3

492 = (18) * (4) (h) /3

Multiply 3 on both sides

1476 = (18) (4) (h)

1476 = 72h

Flip the equation.

72h = 1476

h = 41/2 or 20.5 yards

Step-by-step explanation:

The value of x is 8 in.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

Length = x + 4

Width = x

Height = x - 2

The volume of the rectangular prism = 385 in³

The volume of the rectangular prism = length x width x height

Now,

length x width x height = 385

(x + 4) x (x - 2) = 385

(x + 4) (x² - 2x) = 385

x³ - 2x² + 4x² - 8x = 385

x³ + 2x² - 8x = 385

This is a cubic polynomial.

f(x) = x³ + 2x² - 8x - 385

f(x) = a³ + bx² + cx + d = 0

Using the calculator we get,

Roots:

x = -3.20181 + 5.96339 i (rejected)

x = -3.20181 - 5.96339 i (rejected)

x = 8.40362 = 8

Thus,

The value of x is 8 in.

The probability that the student scores a 70 or below is 0.0013

The given parameters are:

The probability that a student scores 70 or below is represented as:

P(x ≤ 70)

Calculate the z score for x = 70 using:

[tex]z =\frac{x - \mu}{\sigma}[/tex]

This gives

[tex]z =\frac{70 - 82}{4}[/tex]

Evaluate

z =-3

The probability becomes

P(x ≤ 70) = P(z ≤ -3)

Using the z tables of probabilities, we have:

P(x ≤ 70) = 0.0013499

Approximate

P(x ≤ 70) = 0.0013

Hence, the probability that the student scores a 70 or below is 0.0013

Answer:

The lateral area is 439.82  I don't know the single base one and The surface area is 747.7

Step-by-step explanation:

The formula of the function when the graph is analyzed will be y =1.5sin[(pi/4)x] - 3.

From the graph, the mid line is y = -3 and the amplitude will be:

= -1.5 - (-3)

= 1.5

From the mean line to the max is ¼ of a cycle. Therefore, the period will be:

= 4 × 2 = 8

Number of cycles in 2pi will be:

= 2pi/8

= pi/4

Hence, the formula of the function will be y= 1.5sin[(pi/4)x] - 3.

Answer:

    x = 9

Step-by-step explanation:

Sum of all angles of a triangle = 180

                63 + 7x + 6x  = 180

                  63  +  13x    =180

                             13x   = 180 - 63

                              13x  = 117

                                 x  = 117/13

x = 9

Answer:

X= 9

Step-by-step explanation:

The angles in a triangle all add up to 180°

Hence we can form this equation :

63 + 7x + 6x = 180°

Subtracting 63 from both sides:

7x + 6x = 117°

Adding together to find the total X:

13x = 117°

Finally, diving by 13 on both sides:

X = 9

Answer: Each adult’s meal costed $15

Step-by-step explanation:

This situation can be modeled by the following equation:

2a + 3c = 42, where a = the cost of an adult’s meal, and c = the cost of a child’s meal

Since we know from the problem that a child’s meal costs $4, we know c:

2a + 3(4) = 42

At this point, we can just solve the resulting equation for a:

2a + 3(4) = 42

= 2a + 12 = 42 (simplify 3(4))

= 2a = 30 (subtract 12 from both sides)

= a = 15 (divide both sides by 2)

So, the cost of each adult’s meal was $15.
