Answer:

Step-by-step explanation:

The base and height will be the two equal sides of the isosceles right triangle.

⇒ b = h = x cm

[tex]Area \ of \ triangle = \dfrac{1}{2}bh[/tex]

[tex]\dfrac{1}{2}bh = 72 \ cm^{2}[/tex]

[tex]\dfrac{1}{2}*x*x=72\\\\\\\dfrac{1}{2}*x^{2}=72\\\\\\x^{2}=72*2\\\\x^{2}=144\\\\Take \ square \ root,\\\\\sqrt{x^{2}}=\sqrt{144}\\\\x = \sqrt{12*12}\\\\x = 12 cm[/tex]

Hypotenuse² = b² + h²

                      = 12² + 12²

                       = 144 + 144

                     = 288

hypotenuse = √288

                     = 16.97 cm

Answer:

[tex]\large{\boxed{\sf Hypotenuse = 16.97\ cm }}[/tex]

Step-by-step explanation:

Here it is given that the area of a right isosceles ∆ is 72 cm² . Let us assume that each equal side is x . Therefore the height and the base of the ∆ will be same that is x .

[tex]\sf\qquad\longrightarrow Area =\dfrac{1}{2}(base)(height)\\ [/tex]

[tex]\sf\qquad\longrightarrow 72cm^2=\dfrac{1}{2}(x)(x)\\[/tex]

[tex]\sf\qquad\longrightarrow x^2= 144cm^2\\ [/tex]

[tex]\sf\qquad\longrightarrow x =\sqrt{144cm^2}\\ [/tex]

[tex]\sf\qquad\longrightarrow \pink{x = 12cm }[/tex]

Hence we may find hypotenuse using Pythagoras Theorem as ,

[tex]\sf\qquad\longrightarrow h =\sqrt{ p^2+b^2} [/tex]

[tex]\sf\qquad\longrightarrow h =\sqrt{ (12cm)^2+(12cm)^2}\\[/tex]

[tex]\sf\qquad\longrightarrow h =\sqrt{144cm^2+144cm^2}\\[/tex]

[tex]\sf\qquad\longrightarrow h =\sqrt{288cm^2}\\[/tex]

[tex]\sf\qquad\longrightarrow \pink{ hypotenuse= 16.97cm }[/tex]

Hence the hypotenuse is 16.97 cm .

0 T, 4 D

1 T, 3 D

2T, 3D

3T, 2D

4T, 1D

5T, 1D

Step-by-step explanation:

So let's start with what we know!

Gift certificate = $100

T-shirts = $15 each

Dress shirts = $22 each

You need to buy at least one dress shirt in the process and at least spend $90

You can simply find the combinations by going in desmos and writing in:

15x + 22y <= 100

y > 1

15x + 22y >= 90

Find the combinations by looking at the integer values of x, and using only the integer values of y ( do not round them, just cut them down to the integer). Look where all the regions are shaded

The possible combinations are as follows

Note: I am going to initial t-shirts to T and dress shirts to D

0 T, 4 D

1 T, 3 D

2T, 3D

3T, 2D

4T, 1D

The value of cos 4x from the given identity is 0.999

Given the cosine identity

cos8x = 13/36

Determine the value of x

8x = arccos(13/36)
8x = 0.36111

x = 0.36111/8
x = 0.04514

Determine the value of cos4x

cos4x = cos4(0.04514)

cos4(0.04514) = 0.999

Hence the value of cos 4x from the given identity is 0.999

A. (x,y)-(-x,y)

Step-by-step explanation:

1. Look at the first FG, It is Positive X and Positive Y

2. A reflection is simply flipping something to the opposite side, So now look at which part the 2nd FG is.

3. Now as we notice the G is in the Negative X, So that would be -X, But then when we look at the Y, It is in the positives!

Answer:

  287 ft

Step-by-step explanation:

Side lengths of similar triangles are proportional, so we can write and solve a proportion that will tell the length of PR.

ΔRPE ~ ΔOPC so ratios of corresponding sides are the same:

  PR/PO = RE/OC

  PR/(PR +165) = 235/370 . . . . . substitute known values

  74·PR = 47·(PR +165) . . . . . . . . multiply by 74(PR +165)

  27·PR = 7755 . . . . . . . . . . simplify, subtract 47·PR

  PR = 287 2/9 . . . . . . . divide by 27

The distance across the river is about 287 feet.

Answer: A (5, -5.5)

Step-by-step explanation: To find the midpoint of a line segment, you must know the formations of points. Two coordinates are made up of (x1, y1)(x2, y2). Now, to find the answer, you have to add the two x's (which is 4 and 6 = 10) and divide by 2 which equals 5. Now to find the y point, add both y's together. -5 + -6 = -11, and dividing by 2 gives you -5.5

Thus, the midpoint is (5, -5.5)

The flying drones are illustrations of the laws of cosines

Both flying drones would be 128.13 meters apart after 1 hour

For drone A, we have:

So, the distance after one hour is:

Distance = 80 m

The distance is calculated using:

Distance = Speed * Time

For drone B, we have:

So, the distance after one hour is:

Distance = 50 m

The angle between them is calculated as:

[tex]\theta = 360 -(320 - 120)[/tex]

This gives

[tex]\theta =160[/tex]

Using the laws of cosine, the distance (d) between them after 1 hour is:

[tex]d = \sqrt{a^2 + b^2 -2ab\cos(\theta)}[/tex]

So, we have:

[tex]d = \sqrt{80^2 + 50^2 -2*80 *50\cos(160)}[/tex]

Evaluate the expression

[tex]d = 128.13[/tex]

Hence, both drones would be 128.13 meters apart after 1 hour

Reciprocal of trigonometric ratios are also trigonometric ratios. The approximate value of csc(θ) for the corresponding given value of sin(θ) is given by: Option: C: 3.2362

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]

Thus, we see that [tex]\sin(\theta) = \dfrac{1}{\csc{\theta}}[/tex] for a specific angle θ, we get:

Actually, reciprocal of each trigonometric ratio will be a trigonometric ratio, for specific angle.

For the considered case, we're given that,

[tex]\sin(\theta) \approx 0.3090[/tex]

[tex]\sin(\theta) = \dfrac{1}{\csc(\theta)}\\\\\csc(\theta) = \dfrac{1}{\sin(\theta)} \approx\dfrac{1}{0.3090} \approx 3.2362[/tex]

Thus, the approximate value of csc(θ) for the corresponding given value of sin(θ) is given by: Option: C: 3.2362

The value of csc(θ) is 3.2362.

We have given that

sin(θ)=0. 3090

Now we have to find that what is the value of csc(θ)

What is the relation between cos(θ)and sin(θ)

csc(θ)=1/sin(θ)........(1)

Therefore by using (1)

csc(θ)=1/0. 3090........   use the value of sin(θ)

So simplify above we get,

csc(θ)=3.2362

Therefore we get

Answer:

c + 2d = $7.00

2c + 3d = $12.00

Step-by-step explanation:

Hello!

Let:

1 coffee and 2 donuts cost $7.00

This can be repesented by 1c + 2d = $7.00, or c + 2d = $7.00

2 coffees and 3 donuts cost $12.00

This can be represented by 2c + 3d = $12.00

So, the system is :

c + 2d = $7.00

2c + 3d = $12.00

No, it is not an exponential function.
