In terms of the cosecant of a positive acute angle, what is the expression for csc 240°?

The total charge (in dollars) for a rental that includes insurance is C = 0.85M + 22.65.

The given equations are S = 0.60M+17.75 and  I = 0.25M+4.90.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let C be the total charge (in dollars) for a rental that includes insurance.

Total charge = Standard charge + Insurance charge

That is, C = S + I    

Total charge = C = 0.60M + 17.75 + 0.25M + 4.90

= (0.60M + 0.25M) + 17.75 + 4.90

= 0.85M + 22.65

Therefore, the total charge (in dollars) for a rental that includes insurance is C = 0.85M + 22.65.

The requried simplified value of x in the expression \(5^{(3-x)} = 1/125\) is x= 6.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.

Here,
We can start by simplifying the right-hand side of the equation:

\(1/125 = 5^{-3}\)

So we can rewrite the equation as:

\(5^{(3-x)} = 5^{-3}\)

Now we can use the property that if \(a^x = a^y\), then x = y, as long as a is not zero. In this case, a is 5 and it is not zero, so we can apply this property,

3-x = -3

Adding x to both sides, we get,

3 = x - 3

Adding 3 to both sides, we get,

6 = x

Therefore, x = 6.

Answer:

IJ = 2*KL

Step-by-step explanation:

Given that the smaller figure was dilated to create the bigger figure with a scale factor of 2, it therefore means, the dimensions of the smaller figure was increased by times 2 of its dimensions to create the bigger figure.

Thus, the relationship that would exist between line IJ and KL, is that IJ is twice the size of KL.

The relationship is: IJ = 2*KL

For a dialysis experiment, we will need two different sections of dialysis tubing.

One section of dialysis tubing should be filled with a solution containing the molecule or compound you wish to isolate. This solution should be placed in a container and the dialysis tubing should be submerged in the solution.

The second piece of dialysis tubing should be filled with a dialysis buffer, which will act as the medium for the experiment. This solution should also be placed in a container and the dialysis tubing should be submerged in the solution.

The two sections of dialysis tubing should then be connected together with a clamp or a knot, and the experiment can begin. This setup will allow the molecule or compound to move from the first section of dialysis tubing, across the dialysis membrane, and into the second section of dialysis tubing.

The measure of angle A from the given cyclic quadrilateral is 137°.

From the given circle, ∠C=43°.

A cyclic quadrilateral is a four-sided figure where each of the four points of the figure lies on a single circle. This means that all four angles of the quadrilateral measure exactly 90 degrees. A cyclic quadrilateral is sometimes also referred to as a circumscribed quadrilateral because it is defined by the circle around it.

We know that, the sum of opposite angles of cyclic quadrilateral is 180°.

Here, ∠A+∠C=180°

∠A+43°=180°

∠A=180°-43°

∠A=137°

Therefore, the measure of angle A from the given cyclic quadrilateral is 137°.

A new sample size of at least 537 fish to estimate the true mean length with a margin of error of 0.5 centimeters and 95% confidence.

To determine the size of a new sample so that the true mean length is estimated with a margin of error of 0.5 centimeters with 95% confidence, we need to find the standard error of the mean and use it in the formula for the margin of error.

The formula for the margin of error is: ME = z * (σ/√n)

where z is the z-score corresponding to the desired confidence level, σ is the standard deviation of the population, and n is the sample size.

We can estimate the standard deviation of the population using the sample variance, which is given as 34.9.

The standard deviation is the square root of the variance, so σ = √34.9

= 5.91.

To find the standard error of the mean, we divide the standard deviation by the square root of the sample size:

SEM = σ/√n

= 5.91/√n We want the margin of error to be 0.5 centimeters, so we can set up the equation:

0.5 = z * (5.91/√n)

To solve for n, we need to know the value of z for a 95% confidence level.

This corresponds to a z-score of 1.96. Substituting this into the equation gives: 0.5 = 1.96 * (5.91/√n)

Simplifying and solving for n gives: √n = 1.96 * (5.91/0.5) √n

n =(23.18)

n = 537

Answer:

50 degree for X look at pic attached

Step-by-step explanation:

elimination means that we multiply one or both equations by certain numbers, so that the sum of terms of the same variable across both equations is 0.

then the sum of both equations is one equation in one variable.

with the solution of that we go into any of the original equations to solve for the second variable.

I suggest in our case to multiply the first equation by -4. and then x add both equations.

-4x - 16y = -88

4x + y = 13

----------------------

0 - 15y = -75

y = -75/-15 = 5

with this y = 5 we go e.g. into the second original equation.

4x + 5 = 13

4x = 8

x = 8/4 = 2

Trigonometric ratios are special measurements of a right triangle, defined as the ratios of the sides of a right-angled triangle.  There are three common trigonometric ratios: sine, cosine, and tangent

For page 3 question 3,

a) <A + <B = 90 since <C = right angle

b) SinA = BC/AB and CosB = BC/AB

The ratio of the two angles BC/AB ÷ BC/AB = 1

I notice that the ratio of sinA and cosB gives 1

b) The ratio of CosA and SinB will give

BC/AB ÷ BC/AB

= BC/AB * AB/BC = 1

Tan28 = g/i

g/12.2 = tan28

g = 12.2*tan28

g = 12.2 * 0.5317

g = 6.5

b) the angle I is given as 90-28 degrees

<I = 62 degrees

To find the side h we use the Pythagoras theorem

h² = (12.2)² + (6.5)²

h² = 148.84 +42.25

h²= 191.09

h=√191.09

h= 13.8

Answer:

Step-by-step explanation:

We can use trigonometry to solve this problem. Let's draw a right triangle to represent the situation:

        |\

        | \

   h    |  \   9 ft

        |   \

        |    \

        |     \

        -------

        6 ft

Here, h represents the height on the wall where the ladder touches. We want to find the angle of elevation θ.

Using the right triangle, we can write:

sin(θ) = h / 9

cos(θ) = 6 / 9 = 2 / 3

We can solve for h using the Pythagorean theorem:

h^2 + 6^2 = 9^2

h^2 = 9^2 - 6^2

h = √(9^2 - 6^2)

h = √45

h = 3√5

So, sin(θ) = 3√5 / 9 = √5 / 3. We can solve for θ by taking the inverse sine:

θ = sin^-1(√5 / 3)

θ ≈ 37.5 degrees

Therefore, to the nearest tenth of a degree, the angle of elevation the ladder makes with the ground is 37.5 degrees.

Answer:

yes

Step-by-step explanation:

The basic function equivalent to the piecewise-defined function f(x) = x if x ≥ 0 and -x if x < 0 is f(x) = |x|, which represents the absolute value of x.

The given piecewise-defined function f(x) has different expressions for different intervals. For x greater than or equal to zero, f(x) takes the value of x. For x less than zero, f(x) is equal to -x. We need to find a basic function that captures this behavior.

Among the options provided, f(x) = |x| is equivalent to the given piecewise function. The absolute value function, denoted by |x|, returns the positive value of x regardless of its sign. When x is non-negative, |x| equals x, and when x is negative, |x| is equal to -x, mirroring the conditions of the piecewise-defined function.

The function f(x) = |x| represents the absolute value of x and matches the behavior of the given piecewise-defined function, making it the equivalent basic function.

In summary, the basic function equivalent to the piecewise-defined function f(x) = x if x ≥ 0 and -x if x < 0 is f(x) = |x|, which represents the absolute value of x.

Answer:

8 feet

Step-by-step explanation:

Given data

Area= 64 square feet

Base= x feet

Height= x+8 feet

The expression for the area

A= 1/2b*h

substitute

64= 1/2*x*(x+8)

64= 1/2*x^2+8x

64= (x^2+8x)/2

cross multiply

64*2= x^2+8x

128= x^2+8x

rearrange

x^2+8x-128= 0

using the quadratic formula

a=1

b=8

c=-128

x= -b±√b^2-4ac/2a

x= -1±√8^2-4*1*-128/2*1

simplifying

x= 8

x=-16
