Calculate the composite surface area of the figure !!

Rounding to 2 decimal places, the missing side of the right triangle is approximately 15.62 units.

To find the missing side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we are given sides a = 10 and b = 12, and we need to find the missing side c.

Using the Pythagorean theorem:

c^2 = a^2 + b^2

Substituting the given values:

c^2 = 10^2 + 12^2

c^2 = 100 + 144

c^2 = 244

Taking the square root of both sides to solve for c:

c = √244

c ≈ 15.62

Rounding to 2 decimal places, the missing side of the right triangle is approximately 15.62 units.

because 14.74 divided by 5.5 equals 2.68

To calculate the price of 7.25 you multiply the price for 1 pund by 7.25

7.25 * 2.68 = 19.43

A Rectangle with a length of 14 cm and breadth of 3 cm will be formed.

The Rectangle is a quadrilateral which has two sets of equal opposite sides.

Area of a rectangle = L × B = Length × Breadth

Perimeter of a rectangle = 2 [ L + B ] = 2 [ Length + Breadth ]

⇒ l * b = 42                   ...[1]

⇒ 2 [ l + b ] = 34            ...[2]

From equation 2 ,

l + b = 17

b = 17 - l                        ...[3]

Putting the value of b in [1]

⇒ l*[17 - l ] = 42

⇒ 17l - l² = 42

⇒ l² - 17l + 42 = 0

⇒ l² - 14l - 3l + 42 = 0

⇒ l [ l -14 ] - 3 [l - 14] = 0

⇒ [l -14] [l - 3] = 0

⇒ L = 14 , 3

Putting values of B in [1]

B = 14 , 3

But the length of rectangle is 14 cm as length is longer than breadth.

And Breadth of a rectangle is 3 cm.

Hence, a Rectangle with a length of 14 cm and breadth of 3 cm will be formed.

Answer: 584.6

Step-by-step explanation: I just took the test

This question seems extremely odd to me. I don't really even understand what's being asked.

As far as exponential functions go, it's missing an exponent for one. The dependent variable is missing. This essentially saying f(x) = -4 or y = -4. Which is fine, but is definitely not an exponential function and in a very odd and incomplete form to begin with.

=================================================================

Work Shown:

The diagram shows that JK = 12 and GF = 2.5*(JK) = 2.5*12 = 30

The midsegment HL will be the average of the two lengths it is parallel to.

We'll add up the values and then cut the result in half

HL = (JK+GF)/2

HL = (12+30)/2

HL = 42/2

Answer:

its 4543 i6v

Step-by-step explanation:

Vertex is at (3,−1) ; y-intercept is at (0,8) and x-intercepts are at (2,0) and (4, 0)

We know the equation of parabola in vertex form is y = a(x - h)² + k where vertex is at (h,k). Here y = x² - 6x + 8 = (x - 3)² - 9 + 8 = (x - 3)² - 1 ∴ Vertex is at (3,-1) we find y-intercept by putting x = 0 in the equation. So y = 0 - 0 + 8 = 8 and x-intercept by putting y=0 in the equation. So x² - 6x + 8 = 0 or (x - 4)(x - 2) = 0 or x = 4; x = 2 graph{x^2-6x+8 [-20, 20, -10, 10]}

Answer:

here is a simple version

lets make A equal the exponent so (A=^2 or 3 or whatever)

the exponent will be the amount of times you want to repeat the process.

Now lets make x = the first array, so x=3

and lets make y = the second array, y=7

now a simple equation would be (3x)(7y)^A or for this you could say

Answer:

Amber jack 22 pounds

Tarpon 110 pounds

King fish = 44 pounds

White Marlin = 88 pounds

Step-by-step explanation:

Let the weight of the amber jack be x pounds

Kingfish weighed twice as much = 2 * x = 2x pounds

White Marlin weighed 2 times kingfish

= 2x * 2 = 4x pounds

Tarpon weighs 5 times amber jack = 5 * x = 5x

Add all together to give 264

5x + 4x + 2x + x = 264

12x = 264

x = 264/12

x = 22 pounds

Hence ;

Amberjack weighs 22 pounds

Tarpon = 5 * 22 = 110 pounds

Kingfish = 2 * 22 = 44 pounds

White Marlin = 2 times king fish = 2 * 44 = 88 pounds

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:

tan(ACD) = CE / AB

tan(19) = CE / 100

CE = 100 * tan(19)

CE ≈ 34.5 m (rounded to 1 decimal place)

Therefore, the height of the clock tower is approximately 34.5 m.

The value of the F ratio for testing the significance of this model is not 15.56.

For question 10, in a simple linear regression analysis, SST represents the total sum of squares, which measures the total variation in the dependent variable. SSE represents the sum of squared errors, which measures the variation that is not explained by the regression model.

To determine which statement is true, we need to compare the values of SST and SSE.


Now let's move on to question 14. The standard error of estimate is a measure of the variability of the observed values around the regression line. It is not directly related to the sum of the residual squared.

Therefore, the statement that the sum of the residual squared must be 120 is not necessarily true.

Lastly, for question 15, the F ratio is used to test the overall significance of a multiple regression model. It compares the explained variation (SST - SSE) with the unexplained variation (SSE) and takes into account the number of observations and number of explanatory variables.

Given that SST is 900 and SSE is 460, we can calculate the F ratio as follows:

F = ((SST - SSE) / number of explanatory variables) / (SSE / (number of observations - number of explanatory variables))

F = ((900 - 460) / 5) / (460 / (35 - 5))

F = 440 / 460

F ≈ 0.9565

The count of 42 handshakes includes every one of 7 shaking hands with each of the remaining 6, without regard to whether they met before.

The count will include A shaking hands with B, and B shaking hands with A. That handshake will be counted twice, so the number 42 overstates the actual number of handshakes by a factor of 2.

The altitude of Polaris, also known as the North Star, refers to its angle above the horizon when observed from a specific location on Earth.

The altitude of Polaris varies depending on the observer's latitude.

For an observer at the North Pole (latitude 90 degrees), Polaris appears directly overhead, at an altitude of 90 degrees. This means Polaris is at the zenith, the highest point in the sky.

For observers at other latitudes in the Northern Hemisphere, Polaris will appear lower in the sky. The altitude of Polaris is equal to the observer's latitude. For example, if you are at a latitude of 40 degrees north, Polaris will have an altitude of approximately 40 degrees above the horizon.

It's important to note that the altitude of Polaris remains relatively constant throughout the night and throughout the year due to its proximity to the celestial north pole. This makes it a useful navigational reference point for determining direction and latitude in the Northern Hemisphere.

Monomials are algebraic expressions with single terms. They can be said to be specialized cases of polynomials.

We are given the algebraic expression - \(m^6p^{-3}v^{10}\) . \(m^2p^5v^2\)

To simplify it we will use the rules of the indices as follows -

\(a^{m}.\ a^{n} = a^{m+n}\)

Now,

\(m^6p^{-3}v^{10}\) . \(m^2p^5v^2\)

Segregating the like variables, we get,

= \((m^6.\ m^2) .\ (p^{-3}.\ p^{5}) .\ (v^{10}.\ v^{2})\)

by using the rules of indices, we will get,

= \((m^{6+2}) .\ (p^{-3+5}) .\ (v^{10+2})\)

= \((m^{8}) .\ (p^{2}) .\ (v^{12})\)

= \(m^{8}p^{2}v^{12}\)

Hence, the given expression \(m^6p^{-3}v^{10} .\ m^2p^5v^2\) is equivalent to \(m^{8}p^{2}v^{12}\).

Answer:

4.524

Step-by-step explanation:

The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.

We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.

If angles QRP and PSQ are supplementary, their sum is 180°:

(2x + 20)° + 30° = 180°

Now, we can solve for x:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Divide by 2:

x = 65
