Answer:

5= 12.4/2=6.2

6 radius=20.8/2 =10.4

7. radius = 10.2/2=5.1

8.radius =16/2=8

hope it helps

answer:

5. 6.2 yd

6. 10.4 ft

7. 5.1 mi

8. 8 yd

9. 75.40 m

10. 69.12 m

step-by-step explanation:

5 — 12.4 / 2 = 6.2 yd

6 — 20.8 / 2 = 10.4 ft

7 — 10.2 / 2 = 5.1 mi

8 — 16 / 2 = 8 yd

9 — 2π(12) = 75.3982236862 = 75.40 m

10 — 2π(11) = 69.115038379 = 69.12 m

Domain of the function represented by the graph of a quadratic function y = \(x^2\) – 4 with a minimum value at the point (0,-4) is all real numbers.

The correct answer is option D.

To determine the domain of the quadratic function y = \(x^2\) - 4, we need to consider the x-values for which the function is defined. Since a quadratic function is defined for all real numbers, the domain of this function is "all real numbers."

Let's analyze the given function and its graph to understand why the domain is "all real numbers."

The function y =  \(x^2\) - 4 represents a parabola that opens upward, which means it extends infinitely in both positive and negative x-directions. The vertex of the parabola is at the point (0, -4), indicating that the minimum value of the function occurs at x = 0.

Since there are no restrictions or limitations on the x-values for which the function is defined, the domain is unrestricted and encompasses all real numbers. In other words, the function can be evaluated and calculated for any real value of x, whether it is a negative number, zero, or a positive number.

Step-by-step explanation:

Use the sine function since you need to find the hypotenuse but know the opposite side of the angle, since sine is equal to opposite/hypotenuse.

sin8°=\(\frac{550}{c}\)

csin8°=550

c=550/sin8°

Conditional Probability

First, we must complete the totals in the table as follows:

The formula for the conditional probability is:

Where A is an event we know has already occurred, B is an event we want to calculate its probability of occurrence, and P∩A is the probability of both occurring.

We know a female student has been selected, so that is our known event and:

The probability that a female student is also a senior is:

The required probability is 3/16

Answer: See explanation

Step-by-step explanation:

Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.

In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .

Answer:

Step-by-step explanation:

From the question, we are told that to find the sum of the two values 319 + 579, but we are to first convert this two numbers to nearest 10 before estimating the sum.

Step 1: Converting 319 and 579 to nearest 10

To convert to nearest tgen means we are to have just one zero at the end of the number. To do this we will check if the last digit of the value is more than 5, if it is we will round up the value preceding the last number by adding 1 to it but if the last digit of the value is not up to 5,  will round not  up the value preceding the last number.

For 319 to nearest 10 is 320 while 579 to nearest 10 is 580. Note that the last value which is 9 is more than 1, hence the reason for the approximation.

Step 2: Taking the sum of the numbers approximated;

320 + 580

= 900

Sum of the numbers without rounding up is 319+579 = 898

The estimate of the real figure (900) when compared to the actual answer (898) is reasonable because the difference in both value is 2 which is not too significant.

h = hours till they're 58 miles apart

Check the picture below.

so they're travelling in opposite directions, however the combined distances is 58 miles at say "h" hours, by the time that happend Hopi has been walking "h" hours and Brittany has also being walking "h" hours too.

Since the combined distance is 58 miles than if Hopi has covered "m" miles then Brittany covered the slack of "58 - m".

Answer:

it is C

Step-by-step explanation:

Based on the calculations, table B shows a rate that is greater than 1 kilometre per hour.

The average rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the average rate of change can be calculated by using this formula;

The average rate of change = Δy/Δx

= Change in kilometre/Change in an hour

For Table A, we have:

Rate = kilometre/hour

Rate = (1/5)/(7/5)

Rate = 1/5 × 5/7

Rate = 1/7 kilometre per hour.

For Table B, we have:

Rate = (3/4)/(3/8)

Rate = 3/4 × 8/3

Rate = 2 kilometres per hour.

For Table C, we have:

Rate = (2/3)/(4/3)

Rate = 2/3 × 3/4

Rate = 1/2 kilometre per hour.

For Table C, we have:

Rate = (2/3)/(4/3)

Rate = 2/3 × 3/4

Rate = 1/2 kilometre per hour.

For Table D, we have:

Rate = (1/4)/(3/4)

Rate = 1/4 × 4/3

Rate = 1/3 kilometre per hour.

Therefore, table B shows a rate greater than 1 kilometre per hour.

The final amount in Gigi's amount after two years is $637.102.

Compound interest is also known as interest on principal and interest is the practice of adding interest to the principal amount of a loan or deposit.

Gigi opened a savings account.

The principal amount she deposited, P = $600

The interest rate, r = 3% = ( 3 / 100 ) = 0.03

The formula for the compound interest is given as:

\(A=Pe^{rt}\)

Where A is the final amount, P is the principal amount, r is the interest rate, and t is the time in years.

Then the amount in the account after t = 2 years will be:

\(A=Pe^{rt}\\A = 600 \times e^{(0.03 \times 2)}\)

A = 600 × e⁰·⁰⁶

A = 600 × 1.06183654655

A = 637.101927927

A = $637.102

Therefore, the final amount in the account is $637.102.
