Find the value of f, correct to two decimal places.

Answers

Answer 1

Answer:

tan26=f/4 --> f= (tan26)* 4

Step-by-step explanation:

Put (tan26) times 4 into calculator!!!!

SOH, CAH, TOA rules!!

sin(x)=opposite/hypotenuse

cos(x)=adjacent/hypotenuse

tangent(x)=opposite/adjacent

DON'T PUT 90 FOR THE (x) VALUE!!

** (x) here means the angle given to you in the question like 26 in this case.

** opposite and adjacent are the sides according to the angle

**hypotenuse is the opposite side of the right angle

Find the distance between the points (-10,-7) and (2,9).

Answers

20 (units)

Distance formula is:

Sqrt of (x-x1)^2+(y-y1)^2

So define which coordinate is (x,y) and what (x1,y1)

I’m going to define (-10,-7) as (x,y) and (2,9) as (x1,y1)

So plug in your variables!

Sqrt(-10-2)^2+(-7-9)^2

Sqrt-12^2+-16^2

Sqrt144+256

Sqrt400

So sqrt of 400 is 20! :))

Decide whether or not it is a function.

Answers

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.

This example is a function.

Find value of x
Find value of y

Answers

Answer:

x = 17.32

y = 10

Step-by-step explanation:

USsing the SOH CAH TOA identity

sin theta = opp/hyp

sin 30 = y/20

y = 20sin30

y = 20(0.5)

y = 10

Using Pythagoras theorem to get the value of x

20^2 = x^2 + y^2

400 = x^2 + 10^2

400 - 100 = x^2

300 =x^2

x = √300

x = 17.32

Answer:

x = 17.32 ,y = 10

Step-by-step explanation:

Use ratio of cosine :-

cos 30° = x/20 √3/2 = x/20 x = √3/2 * 20 x = 10√3 x = 10 * 1.732 x = 17.32

Use ratio of sine :-

sin 30° = y/20 1/2 = y/20 y = 20 *1/2 y = 10

Answer:

36.8 ft^2

Step-by-step explanation:

The surface is consisted of 2 triangles and 3 rectangles. The two triangles are the same the Area together = 2.2*1.5 = 3.3 ft^2, then the 3 rectangles are 2.2 X 5, 1.5 X 5 and 3 X 5, so to add them together to get the surface area so SA = 3.3 + 2.2*5 + 1.5*5 + 3 *5 = 36.8 ft^2.

plz quick solve for f

Answers

Answer: f = 100

Step 1.

We'll need to expand 3(f - 91) by multiplying a term and an expression. The following product distributive property will be used: A(B + C) = AB + AC.

In the example, the expression will consist of 2 terms.

First term: 3 and f.

Second term: 3 and -91

Rewrite 3(f - 91) like this.

3f - 3 × 91

Step 2.

Multiply 3 by 91.

3 × 91 = 273

Hence, the answer is 100.

I have a prism with the dimension of 6cm by 12cm by 15 cm. Calculate the volume of the prism, and then give the dimensions of three different prisms that each have 1/3 of thr volume.
Prism 1
Prism 2
Prism 3

Answers

Answer:

Volume = 1080 cubic cmPrism 1 = 2 cm by 5 cm by 36 cmPrism 2 = 3 cm by 10 cm by 12 cmPrism 3 = 4 cm by 6 cm by 15 cm

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

Explanation:

To find the volume of the current prism, we multiply length width and height to get 6*12*15 = 1080

Take 1/3 of this to get (1/3)*1080 = 360

To find three different prisms where they have a volume of 360, we just need to think of ways to multiply to 360 using 3 numbers.

Here are some possibilities:

2 * 5 * 36 = 3603 * 10 * 12 = 3604 * 6 * 15 = 3604 * 9 * 10 = 3608 * 9 * 5 = 360

There are other possibilities as well, but you only need to pick three from that list. Or you can come up with other combos as well as long as the three numbers multiply to 360.

If we go with the first three rows for prisms 1, 2, and 3 in that exact order, then

prism 1 has dimensions: 2 cm by 5 cm by 36 cmprism 2 has dimensions: 3 cm by 10 cm by 12 cmprism 3 has dimensions: 4 cm by 6 cm by 15 cm

Please need help on this one h as be no clue how to do this

Answers

Answer:

y = -2x

Step-by-step explanation:

Equation in slope-intercept form is y = mx + b.

m = slope = ∆y/∆x

Using any two points on the line, say (0, 0) and (-20, 40),

Slope (m) = (40 - 0) / (-20 - 0) = 40/-20

Slope (m) = -2

b = y-intercept = the value of y when x = 0.

b = 0

To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b

Thus:

y = -2x + 0

y = -2x
