Answer:

D

Step-by-step explanation:

So we know that:

[tex]\cos(A)=1/3[/tex]

To co-function identities state that:

[tex]\cos(\theta)=\sin(90\textdegree-\theta)[/tex]

Therefore, this is the same as:

[tex]\cos(A)=\sin(90\textdegree-A)[/tex]

B is correct.

Additionally, recall that in a right triangle, the two other angles must add up to 90. In other words:

[tex]A+B=90[/tex]

Subtract A from both sides:

[tex]B=90-A[/tex]

So we can make the substitution:

[tex]\sin(90-A)=\sin(B)[/tex]

Thus, A is also correct.

The correct answer is D .

Answer:

71, 72, 73

Step-by-step explanation:

So we want to find three consecutive integers that equal 216.

Let the first integer be n.

Then the second integer is n+1, and the third integer is n+2.

Thus:

[tex]n+(n+1)+(n+2)=216[/tex]

Combine like terms:

[tex]3n+3=216[/tex]

Subtract 3 from both sides:

[tex]3n=213\\[/tex]

Divide 3 from both sides:

[tex]n=71[/tex]

So, the first term is 71.

And the other two is 72 and 73.

And we are done :)

0                                              0.25

1                                               0.5

2                                              0.25

b. The expected variable value of X; E(X) = 1

Step-by-step explanation:

Given that:

number of cameras = 6

numbers of defective  = 3

the probability of defective camera p = 3/6 = 0.5

sample size n = 2

Then X = {0,1,2}

Suppose X is the given variable that represents the number of defective cameras in the sample.

∴

X [tex]\sim[/tex] Bin (n =2, p = 0.5)

The probability mass function of binomial distribution can be computed as :

[tex]P(X =x) = (^n_x) p^x (1-p)^{n-x}[/tex]

For  ;

x = 0

The probability P(X=0)  [tex]= (^2_0) 0.5^0 (1-0.5)^{2-0}[/tex]

[tex]P(X=0) = \dfrac{2!}{0!(2-0)!} \times 1 \times 0.5^2[/tex]

[tex]P(X=0) =1\times 1 \times 0.25[/tex]

[tex]P(X=0) = 0.25[/tex]

For :

x = 1

The probability P(X=1)  [tex]= (^2_1) 0.5^1 (1-0.5)^{2-1}[/tex]

[tex]P(X=1) = \dfrac{2!}{1!(2-1)!} \times 0.5^1 \times 0.5^1[/tex]

[tex]P(X=1) =2 \times 0.5 \times 0.5[/tex]

[tex]P(X=1) =0.5[/tex]

For :

x = 2

The probability P(X=2)  [tex]= (^2_2) 0.5^2 (1-0.5)^{2-2}[/tex]

[tex]P(X=2) = \dfrac{2!}{2!(2-2)!} \times 0.5^2 \times 0.5^0[/tex]

[tex]P(X=2) =1 \times 0.5^2 \times 1[/tex]

[tex]P(X=2) =0.25[/tex]

The probability of X

k                                             P(X=k)

0                                              0.25

1                                               0.5

2                                              0.25

The expected variable value of X can be computed as:

E(X) = np

E(X) = 2 × 0.5

E(X) = 1

Answer: 60

Step-by-step explanation:

[tex]A = s^2\\\\frac{dA}{dt}=2s \frac{ds}{dt}\\36=s^2 \\ s=6\\\frac{dA}{dt} = 2(6)(5)=60 \frac{cm^2}{s}[/tex]

Answer:

The area of the square is increasing at a rate of 60 cm²/s

Step-by-step explanation:

Let [tex]l[/tex] be the length of the side of the square

Hence, The area of the square is given by

[tex]A = l^{2}[/tex]

Where [tex]A[/tex] is the area of the square

From the question, each side of a square is increasing at a rate of 5 cm/s, that is,

[tex]\frac{dl}{dt} = 5 cm/s[/tex]

Now, to determine the rate at which the area of the square is increasing, That is [tex]\frac{dA}{dt}[/tex]

To find [tex]\frac{dA}{dt}[/tex], differentiate [tex]A = l^{2}[/tex] with respect to [tex]t[/tex]

From, [tex]A = l^{2}[/tex]

[tex]\frac{dA}{dt} = \frac{d(l^{2}) }{dl}[/tex] ×[tex]\frac{dl}{dt}[/tex]

[tex]\frac{dA}{dt} = 2l[/tex] ×[tex]\frac{dl}{dt}[/tex]

Now, to determine the rate at which the area of the square is increasing when the area of the square is 36 cm²

First, we will determine the length at this instance,

From, [tex]A = l^{2}[/tex]

[tex]36 = l^{2}\\ \sqrt{36} = l\\6 = l\\l = 6cm[/tex]

The length at this instance is 6cm

To determine the rate at which the area of the square is increasing at this instance

[tex]l = 6cm\\[/tex]

From the question,  [tex]\frac{dl}{dt} = 5 cm/s[/tex]

Hence,

[tex]\frac{dA}{dt} = 2l[/tex] ×[tex]\frac{dl}{dt}[/tex]

[tex]\frac{dA}{dt} = 2(6)[/tex] × [tex]5[/tex]

[tex]\frac{dA}{dt} = 60 cm^{2}/s[/tex]

Hence. the area of the square is increasing at a rate of 60 cm²/s

Answer: b, d, e

Trapezoids are quadrilaterals (a shape with four sides) and they have two pairs of sides; one pair are parallel, and the other pair are not.

Picture shown below.

The correct properties of a trapezoid are:

A trapezoid is a quadrilateral, which means it has four sides. One defining property of a trapezoid is that it has one pair of opposite sides that are parallel. This means that these parallel sides never intersect.

Additionally, a trapezoid has another pair of opposite sides that are not parallel, which means they do intersect. Unlike a rectangle or square, a trapezoid does not have all sides congruent.

Lastly, the diagonals of a trapezoid do not necessarily intersect at right angles. The angle formed by the intersection of the diagonals can vary in size. These properties collectively distinguish a trapezoid from other quadrilaterals and make it a unique shape.

Answer:

No it is not satisfied

Step-by-step explanation:

The one-way ANOVA is used to measure whether the difference between the means of two independent groups are statistically significant.

For it to be satisfied, there has to be one independent variable which is categorical and one dependent variable. The dependent variable on its own has to be a continuous variable

The assumptions are:

1. Equal variance between population

2. Independence between observations

3. The random samples have to be gotten from a normal population.

Given;

Mass of a box (m) = 300kg

Area of box (a) = 15m²

Pressure exerted by the box (P) = ?

Acceleration due to gravity (g) = 9.8m/s²

Here,

Pressure = Force / Area

= mass × acceleration due to gravity / Area [Since, force=mass×acceleration due to gravity]

= 300 × 9.8 / 15

Answer:

The radius is [tex] 2\sqrt{15} [/tex]

The center is (3, 3)

Step-by-step explanation:

Equation of circle in standard form with center at (h, k) and radius r:

[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]

We need to complete the square in x and y.

[tex] x^2 + y^2 - 6x - 6y = 42 [/tex]

Separate x-terms and y-terms:

[tex] x^2 - 6x + ~~~~~y^2 - 6y + ~~~~~ = 42 + ~~~~~ + ~~~~~ [/tex]

To complete the square, you square half of the linear term's coefficient.

Linear term in x: -6x

Coefficient: -6

Half of the coefficient: -3

Square half of the coefficient: 9

We need to add 9 to both sides to complete the square in x.

The linear term in y is -6y, so we do the same and we also need to add 9 to both sides to complete the square in y.

[tex] x^2 - 6x + 9 + y^2 - 6y + 9 = 42 + 9 + 9 [/tex]

[tex] (x - 3)^2 + (y - 3)^2 = 60 [/tex]

Now that we have the equation in standard form, we can get the radius and center of the circle.

[tex] r^2 = 60 [/tex]

[tex] r = \sqrt{60} [/tex]

[tex] r = \sqrt{4 \times 15} [/tex]

[tex] r = 2\sqrt{15} [/tex]

The radius is [tex] 2\sqrt{15} [/tex]

The center is (3, 3)

Answer:

11 feet

Step-by-step explanation:

The area of a square is simply the side of the square squared.  This can be written as an equation as follows:

A = l^2

where A is the area of the square and l is the length of a side of the square.

Using this, we can find the length of the side.

121 = l^2

sqrt(121) = sqrt (l^2)

11 = l

Hence, the side length of the square is 11 feet.

Answer:

to the right of x = 2 the function is increasing

{ x | x > 2}

Step-by-step explanation:

Recall that this is a quadratic function, and therefore responds to the shape of a parabola. In this case is also a parabola with branches opening up since the coefficient of the square term is positive. So, we just need to find where the vertex is located, and we know that to the left of the x-value of the vertex the function is decreasing, and to the right of it the function is increasing.

The formula for the x of the vertex of a parabola of the form:

[tex]y=ax^2+bx+c[/tex]

is  [tex]x_{vertex}=\frac{-b}{2\,a}[/tex]

which in our case gives:

[tex]x_{vertex}=\frac{-b}{2\,a} =\frac{4}{2} =2[/tex]

Therefore, to the left of x = 2 the function decreases , and to the right of x = 2 the function is increasing.
