C

Step-by-step explanation :

The side length is 30 and if it's 3cm for 5 that would be 18, and since we are doing area we need to multiple that 18 by itself since it's a square and squares side lengths are the same

Answer:

x=4

Step-by-step explanation:

7/9 - x/9 = 1/3

I like to get rid of fractions so I will multiply each side by 9

9*(7/9 - x/9) = 1/3*9

7 - x = 3

Subtract 7 from each side

7-x-7 = 3-7

-x= -4

Multiply each side by -1

x =4

The value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex].

Trigonometric functions are  the periodic functions which denote the relationship between angle and sides of a right-angled triangle.

We have,

[tex]Sin(A) = \frac{4}{5}[/tex] ,    [tex]\frac{\pi }{2} < A < \pi[/tex]

[tex]Sin(B) = \frac{-2\sqrt{5} }{5}[/tex] ,   [tex]\pi < B < \frac{3\pi }{2}[/tex]

So,

Using identity ;

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

So,

First find [tex]SinB[/tex] and [tex]CosA[/tex];

i.e.

[tex]CosB=\frac{-\sqrt{5} }{5}=\frac{-1}{\sqrt{5} }[/tex],   [tex]\pi < B > \frac{3\pi }{2}[/tex]

[tex]CosA=\frac{-3}{5}[/tex],    [tex]\frac{\pi }{2} < A > \pi[/tex]

Now,

Substituting values,

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

[tex]Cos(A - B)= ((\frac{-3}{5})\ *\ \frac{-1}{\sqrt{5}} ) +((\frac{4}{5})\ *\ \frac{-2\sqrt{5} }{5} )[/tex]

Simplify,

[tex]Cos(A - B)= (\frac{3 }{5\sqrt{5}} ) -(\frac{8 }{5\sqrt{5}})[/tex]

[tex]Cos(A - B)= (\frac{-5 }{5\sqrt{5}} )[/tex]

[tex]Cos(A - B)= (\frac{-1 }{\sqrt{5}} )[/tex]

Or we can write

[tex]Cos(A - B)= (\frac{-\sqrt{5} }{5} )[/tex]

Hence, we can say that the value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex] which is given in option (b).

Answer:

Length = 3

Step-by-step explanation:

the formula for area of a rectangle is Area = Base (width) x Height (length)

so plug in out values: 3/2 = 1/2 x H

divide both sides by 1/2 to find the height/length: 3/2 ÷ 1/2 = Height

to divide a fraction by a fraction, flip the divisor and change the sign from ÷ to ×

so you get 3/2 × 2/1 = Height

the 2 cancels out, so you get: 3 = height/length

Answer:

The equation in the point-slope form will be:

Step-by-step explanation:

Given

Using the point-slope form of line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

here

substituting the values m = 2/3 and the point (-3, 5)  in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

Thus,  the equation in the point-slope form will be:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

NOTE: The equation in the point-slope can be further simplified such as:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{2}{3}\left(x+3\right)+5[/tex]

[tex]y=\frac{2}{3}x+7[/tex]

Answer:

Step-by-step explanation:

If you plot the vertex and the directrix, you'll see that the directrix is a horizontal line above the vertex. That means that the parabola opens upside down and has the standard equation:

[tex](x-h)^2=-4p(y-k)[/tex] where h and k are the coordinates of the vertex and p is the number of units between the directrix and the vertex. From the vertex we determine that h = 6 and k = 2. And by counting, we determine that p = 2. Filling in the equation then gives us:

[tex](x-6)^2=-4(2)(y-2)[/tex] and simplifying just a tiny bit will get us what we need:

[tex](x-6)^2=-8(y-2)[/tex] which is the second choice down.

The equation of this parabola in standard form is (x - 6)²  = -8(y - 2) if the vertex of a parabola is (6,2) option (C) is correct.

It is defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the parabola:

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

It is given that:

The vertex of a parabola is (6,2), and the equation of its directrix is y = 4.

The standard form of the parabola:

y = a(x - h)² + k

y = a(x - 6)² + 2

As the directrix is y = 4

The equation of the parabola becomes:

(x - 6)²  = -8(y - 2)

Thus, the equation of this parabola in standard form is (x - 6)²  = -8(y - 2) if the vertex of a parabola is (6,2) option (C) is correct.

Answer:

It would take hans around 5 hours to drive 275

Step-by-step explanation:

first we divide 715 by 13 which gives us 55, so in 1 hour he can drive 55 miles then we do 275 divided by 55 which gives us 5, so the answer is 5.

At the rate 55 miles per hour, it takes 5 hours to travel 275 miles.

Given that, Hans drove 715 miles in 13 hours.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Here, average speed = 715/13

= 55 miles per hour

At the same rate,

Time = 275/55

= 5 hours

Therefore, at the rate 55 miles per hour, it takes 5 hours to travel 275 miles.

The second graph is the inverse secant function.

To find graph of the inverse secant function.

Inverse trigonometric functions are simply defined as the inverse functions of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant functions.

The reciprocal cosine function is secant: sec(Ф)=1/cos(Ф). The reciprocal sine function is cosecant, cosec(Ф)=1/sin(Ф).

So, the second graph is the inverse secant function.
