The values of a = 17 and b = - 56

that make the following piece wise defined function both continuous and differentiable everywhere.

A continuous function in mathematics is one that doesn't change value unexpectedly due to discontinuities, or breaks in the function's continuity. A continuous function in mathematics is a function that causes the value of the function to continuously vary as a result of a continuous variation of the argument, or a change without a leap. Thus, there aren't any discontinuities—rapid changes in value.

conditions are:

1.

f(x) is continuous if,

[tex]\lim_{x \to \ 5^{-}}f(x)[/tex] = [tex]\lim_{x \to \ 5^{+}}f(x)[/tex] = f(5)

2.

differentiable if,

[tex]\lim_{x \to \ 5^{-}}f^'(x)[/tex] = [tex]\lim_{x \to \ 5^{+}}f^'(x)[/tex]

for 1st condition:

⇒ [tex]\lim_{x \to \ 5^{-}}f(x) = \lim_{x \to \ 5^{+}}f(x)[/tex]

⇒ [tex]\lim_{x \to \ 5^{-}}(-3x -6) = \lim_{x \to \ 5^{+}}(-2x^2+ax+b)[/tex]

The amount of money put by Shannon in her account is $300.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.

Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.

Given that Shannon put some money in her savings account. After 6 months, she earned $10.50 in interest. If the interest rate was 7%,

The amount will be calculated as:-

SI = ( P x R x T ) / 100

10.50 = ( P x 7 x 1 ) ( 2 x 100 )

P = ( 10.50 x 2 x 100 ) / ( 7 )

P = $300

Therefore, $300 has been deposited into Shannon's account.

Answer:

55%

Step-by-step explanation:

To find the percentage of juveniles in the local deer population, we need to calculate the proportion of juveniles in the total population and convert it to a percentage.

First, find the total number of deer in the population by adding the number of juveniles and adults:

110 juveniles + 90 adults = 200 deer

Next, divide the number of juveniles by the total number of deer and multiply by 100 to convert to a percentage:

110 juveniles / 200 deer * 100 = 55%

Therefore, 55% of the local deer population were juveniles.

Addition with the number 3.

Next numbers will be 15, 18, 21,...

i) The profit/loss when no cars are produced is a loss of 6600 Rupees.

II) The break even point is at 20 cars

III) The profit/loss if 400 cars are produced is;  a loss of 13400Rupees.

(i) When no cars are produced, x = 0.

Thus, plugging this value into the function p(x) = -x² + 350x - 6600, we have;

p(0) = -0² + 350(0) - 6600 = -6600.

Therefore, the profit/loss when no cars are produced is a loss of 6600 thousand Rupees.

(ii) The break-even point is the point at which the profit is zero, i.e., p(x) = 0. Setting p(x) = 0 and solving for x, we find that;

-x² + 350x - 6600 = 0

x = 20

Therefore, the break-even point is x = 20 cars. T

(iii) If 400 cars are produced, the profit can be found by plugging this value into the function p(x) = -x² + 350x - 6600.

We find that p(400) = -400² + 350(400) - 6600

= -160000 + 140000 + 6600 = -13400. Therefore, the profit/loss if 400 cars are produced is a loss of 13400 Rupees.

In response to the query, x is equal to 60°, 120°, 240°, and 300°. These four options are the answer to the equation.

A mathematical equation is a statement that two amount or values are equal, such as 6 x 4 = 12 x 2. 2. A noun that counts. An equation is applied when several or more factors must be considered jointly in order to understand or explain the whole situation.

This equation can be solved using the trigonometric identity:

[tex]sinx = \sqrt{ (1 - cos^2x)}[/tex]

This identity can be used as a substitution in the equation:

5 sinx - 5 cosx = 2

5 [tex]\sqrt{(1 - cos^2x) }[/tex] - 5 cosx = 2

5 sqrt[tex](1 - cos^2x)[/tex]) = 7 + 5 cosx

Squaring both sides:

25([tex]1 - cos^2x[/tex]) = 49 + 70 cosx + 25 [tex]cos^2x[/tex]

25 - 25 [tex]cos^2x[/tex] = 49 + 70 cosx + 25 [tex]cos^2x[/tex]

0 = 74 + 45 cosx

45 cosx = -74

cosx = -74/45 = -2/3

The inverted cosine function can be used to determine that x = cos-1(-2/3). x must be within the range of 0° to 360°, hence x must be 300°.

5 sin - 5 cos - 5(-1/2) = 5 sqrt(3)/2 + 5/2 = 2 + 2.5 = 2.5

Since the left side of the equation is not equal to 2, x = 300° is not a solution to the equation.

We can repeat this process for the other solutions to the equation:

x = 60°, x = 120°, x = 240°, and x = 300°

These are the four solutions to the equation for 0° <= x < 360°.

[tex]V= [0,16] \int\limits {4y^2 \sqrt{(256 - y^2)} } \, dy[/tex] would be the integral that gives the volume of the solid.

What is Disk method of integration?

Disc integration is a method for estimating the volume of a solid of revolution of a solid-state material when integrating along an axis "parallel" to the axis of revolution in integral calculus.

The volume of the solid can be found using the disk method of integration. In this method, we consider thin slices of the solid perpendicular to the x-axis, each of which is a disk with a square cross-section.

The volume of each slice is equal to the product of the area of its cross-section and its thickness, which is equal to the difference in x-coordinates between the top and bottom of the slice.

Let's call the top-right corner of the square cross-section (x, y, z). We k[tex]x^2 + y^2 = 256[/tex]

And we also know that the side length of the square is equal to 2y. So, the area of the cross-section is equal to [tex](2y)^2 = 4y^2.[/tex] The volume of the slice is equal to [tex]4y^2 dx.[/tex]

Since the semicircle is centered at the origin, the value of y ranges from 0 to 16.

The value of x ranges from 0 to the square root of [tex]256 - y^2.[/tex]Using these ranges, the volume of the solid can be calculated as follows:

[tex]V=\int\limits {[0,16] 4y^2 \sqrt{(256 - y^2)} } \, dy\\V= [0,16] \int\limits {4y^2 \sqrt{(256 - y^2)} } \, dy[/tex]

This is the integral that gives the volume of the solid.

Therefore, [tex]V= [0,16] \int\limits {4y^2 \sqrt{(256 - y^2)} } \, dy[/tex] would be the integral that gives the volume of the solid.

Answer:

Around 11:15 am

Step-by-step explanation:

Let h represents the number of hours the plumber works

Since the plumber charges $65 fee plus $75 per hour, the bill can be calculated by:

→ bill = 65 + 75h

Since the bill is $195.25

→ 195.25 = 65 + 75h

→ 75h = 130.25

→ h = 1.74

1.74 implies that the plumber worked almost 1 hour and 45 minutes. Since the plumber started at 9:30, the repair was completed around 11:15 am.

The probability that the discrete random variable x takes a value less than or equal to 50 is 0.50, since F(50) = 50/100 = 0.50.

F(x) = x/100

Then, the probability that x takes a value less than or equal to 50 is 0.50, since

F(50) = 50/100 = 0.50

The cumulative distribution function (CDF) of a random variable is a function that gives the probability that the random variable is less than or equal to a certain value. In this case, the CDF of the random variable x is given by F(x) = x/100.

Therefore, to find the probability that x takes a value less than or equal to 50, we simply need to evaluate the CDF at x = 50. This is done by substituting 50 into the CDF, which gives us F(50) = 50/100 = 0.50. This means that the probability that x takes a value less than or equal to 50 is 0.50.

Step-by-step explanation:

Since the angles are similar, each of the angles of ΔEFG must be equal to each of the corresponding angles of ΔHIJ

Specifically, m ∠J in ΔHIJ = m∠G in Δ EFG

Let's first find ∠G

Since EFG is a right triangle,

The Pythagorean Theorem, sometimes known as the Pythagorean Theorem, is the basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides. The Pythagorean Theorem, often known as the generic algebraic notation a2 + b2 = c2, states that the square that crosses the hypotenuse of a right triangle opposite the right angle equals the sum of the squares that span the sides of a right triangle.

By Pythagorean theorem

a = 5.7 meters and c = 9.6

b = [tex]\sqrt{a^2 + b^2}[/tex]

b = [tex]\sqrt{32.49 + 92.16}[/tex]

Step-by-step explanation:

Proportion method is applied:

                     1.5 inches on a map = 10.8 miles of actual distance

                  ∴ 1 inches on the map = x miles of the actual distance

Cross-multiplication is applied:

(1.5 inches)(x miles) = (1 inch)(10.8 miles)

x needs to be isolated and made the subject of the equation:

x miles = [tex]\frac{(1 inch)(10.8 miles)}{1,5 inches}[/tex]

Inches in the numerator and denominator will cancel eachother out:

x miles = [tex]\frac{10.8 miles}{1.5}[/tex]
