The area of the given circle is 36.298 cm square.

Here, we are given that f is the function that determines the area of a circle (in square cm) that has a radius of r cm.

The area of a circle is given the the formula as follows-

area of a circle = πr^2

⇒ f(r) = πr^2

The value of π is approximately 3.14

⇒ f(r) = 3.14r^2

Now, we are given that the radius of a circle is 3.4 cm.

Thus, its area will be-

f(3.4) = 3.14 × 3.4 × 3.4

= 3.14 × 11.56

= 36.298

Thus, the area of the given circle comes out to be 36.298 cm square.

Answer:

  (c)  inconsistent equation

Step-by-step explanation:

You want to know if the equation -6x+6x-6=2-5 is an identity, conditional, or inconsistent.

The simplified equation, after combining like terms, is ...

  -6 = -3

This is an "inconsistent" equation, always false.

Using the relation between velocity, distance and time, it is found that a rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

Velocity is distance divided by time, that is:

v = d/t.

For the first 120 km, the rate is of 90 km/h, hence the parameters are given as follows:

d = 120, v = 90.

Hence the time is given by:

90 = 120/t1

t1 = 120/90

t1 = 1.33 hours.

For the second part of the trip, the parameters are given as follows:

t = 1.25, v = 64.

The time is 1.25 hours because 15 minutes is one fourth(15/60) = 0.25 of an hour.

Hence the distance found as follows is:

64 = d/1.25

d = 1.25 x 64

d = 80

The distance for the first two parts is given by:

120 + 80 = 200 km.

This is equivalent to 7/8 of the trip, hence the total distance is:

7/8d = 200

d = 200 x 8/7

d = 228.57 km.

For a rate of 80 km, we have that the time has to be of:

80 = 228.57/t

t = 228.57/80

t = 2.86 hours.

The time of the first two parts is:

1.33 + 1.25 = 2.58 hours.

2.86 - 2.58 = 0.28 hours.

Hence the last 228.57 - 200 = 28.57 km have to be traveled in 0.28 hours, for a rate of:

v = 28.57/0.28 = 102 km/h.

A rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

Answer:(0,4)

Step-by-step explanation:

for the two given fractions 3/4 and 1/6 we have:

Here we have two fractions, 3/4 and 1/6, and we want to find the sum, product, and quotient between them.

First let's do the sum:

3/4 + 1/6

We just need to find a common denominator, which can be 12, so we can rewrite it as:

9/12 + 2/12 = 11/12

The sum of the two fractions is 11/12

Now the product, it is, we multiply denominator with denominator and numerator with numerator, we will get:

(3/4)*(1/6) = (3*1)/(4*6) = 3/24 = 1/8

The product between the two fractions is equal to 1/8.

Finally, the quotient, this is:

The product between the first numerator and second denominator, and between the first denominator and second numerator, so the quotient becomes:

(3/4)/(1/6) = (3/4)*(6/1) = (3*6)/(4*1) = 18/4 = 9/2

Then we conclude that for the two given fractions 3/4 and 1/6 we have:

Answer: $466.

Step-by-step explanation:

Add all the numbers in the graph together, you get 194.

Now, subtract 194 from 660, you get 466. That's how much profit the company makes.

The required generated profit on iPhone 4s is given as $466.2.

The cost price is defined as the is the price of producing something while the selling price is the amount that the buyer pays.

Here,
As of the mentioned data,
Cost of making an iPhone = $193.8
The selling price of the iPhone = $660

Profit is meant how much money is generated from the product besides the product cost price.
Profit  = selling price - cost price
Profit= 660 - 193.9
Profit = $466.2

If Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

The ratio is the numerical relationship that one variable has when compared with another.

The ratio has the same meaning as proportion.

Ratios are represented in percentages, decimals, fractions, or with the ratio sign (:).

Another way to calculate it is to examine the ratio against the number of papayas he has.

Benjamin has 25 papayas, which is half of 50 (25/50).  This means he has half of the pears, which is 47 (94/2).

Papayas = 25

The ratio of papayas to pears = 50:94

For every 50 papayas Benjamin has, he has 94 pears.

The number of pears he has = 47 (25/50 x 94)

Thus, if Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

The formula for determining the average rate of change across a given interval of a function is expressed as:

Average rate of change = g(b) - g(a)/b - a.

Given the function, g(x) = -2x³ + 5 to find the average rate of change from x = -4 to x = 3, do the following:

a = -4

g(a) = g(-4) = -2(-4)³ + 5 = -2(-64) + 5 = 128 + 5 = 133

b = 3

g(b) = g(3) = -2(3)³ + 5 = -2(27) + 5 = -54 + 5 = -49

Substitute the values into g(b) - g(a)/b - a:

Average rate of change = (-49 - 133)/(3 - (-4))

Average rate of change = -182/7

Average rate of change = -26

Thus, the average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

The two values of y after factorizing the given quadratic equation are 0, -0.5

The given equation is quadratic as the order of the equation is 2. In a quadratic equation with a single variable, the variable will have two different values which satisfy the equation. These values of the variable can be real and different, real and equal, or imaginary.

So, there will be two values of y.

Consider the given equation,

10y^2 + 12y = 7y

10y^2 +12y - 7y = 0

10y^2 + 5y = 0

Since the coefficients of y and y^2 are both multiples of 5,

5*(2y^2 + y) = 0

2y^2 + y = 0

Taking y as a common factor,

y*(2y+1) = 0

Now, we get two cases,

y = 0 or 2y + 1 = 0 => y = -(1/2) = -0.5

Therefore, y = 0 or y = -0.5

The interval at which the function x³ + 3x² - 4x - 12 increases is

x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).

We have,

x³ + 3x² - 4x - 12

We need to draw a graph to see at which interval the graph is increasing.

The graph is given below.

We see that the graph is increasing from x = -∞ to x = -2.5 and from  x = -2.5 it decreases till x = 0.5 and again from x = 0.5 it increases to x = ∞.

So we can write the interval as:

x ∈ (- ∞, - 2.5) and  x ∈ (0.5, ∞)

We can write it as one single interval as:

S = (- ∞, - 2.5) ∪ (0.5, ∞)

The baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.

In this problem we know that a baseball coach spends a total of $ 118.25 on buying 11 pizzas. First, we need to estimate the amount of money spent per each pizza bought, which is found by means of multiplication tables and the supposition of truncation, that is, finding the maximum integer less than or equal to the real total cost.

By direct inspection we find that 10 times the 11 pizzas is equal to $ 110, which is the maximum integer less than or equal to the real total cost. Then, we estimate a cost of $ 10 per each pizza bought. Second, the exact unit cost is found by dividing the total by the number of pizzas:

c = $ 118.25 / 11

c = $ 10.75

Answer:

One geranium is $3

Step-by-step explanation:

Let r = roses and g = geraniums

14r + 8g = 122

12r + 12g = 120

Multiply first equation by -3 and the second by 2 (we are trying to get terms that cancel when we add the two equations)

-42r - 24g = -366

+24r + 24g = 240

Add

18r = 126

r = 7, so one rose is $7

Put this into either of the original equations

14(7) + 8g = 122

98 +8g = 122

8g = 24

g = 3, so one geranium is $3

An equivalent numerical expression with whole-

number exponent using these laws can be written as:

1) 2² × 2³ = 2^5     => using product of Powers

2) 2² × 3² = (2×3)² = 6²      => using power of a Product

3) (2²)³ = 2^6      => using power of a power

Step-by-step explanation:

First of all, let us understand some terms like;

1) Exponentiation: It is the mathematical process of raising one integer to the power of another. The base is the first integer, while the exponent is the second.

2) Power: A power is a phrase that depicts the same component being multiplied repeatedly.

3) Exponent: The number of times the base is used as a factor is represented by the exponent.

Now, let us understand the 7 Laws of Exponents;

1) a^m × a^n = a^(m+n)   => Product With the Same Bases

2) a^m / a^n = a^(m-n)    => Quotient with Same Bases

3) (a^m)^n = a^(m×n)    => Power Raised to a Power

4) a^n × b^n = (ab)^n    => Product to a Power

5) a^n / b^n = (a/b)^n    => Quotient to a Power

6) a^0 = 1     => Zero Power

7) a^(-m) = 1/a^m    => Negative Exponent Rule

Furthermore, an equivalent numerical expression with whole-

number exponent using these laws can be written as:

1) 2² × 2³ = 2^5     => using product of Powers

2) 2² × 3² = (2×3)² = 6²      => using power of a Product

3) (2²)³ = 2^6      => using power of a power
