There are values of tso that sin t= .6 and cost=.8
A. True
B. False

Answers

The correct answer to the given postulate as required in the task content is; Choice A; True.

Which is correct about the given postulate?

It follows from the task content that it is required to verify if there are values of t such that; sin t= .6 and cost=.8.

Recall from square trigonometric identities that;

sin² x + cos² x = 1.

To verify if sin t= .6 and cost=.8 satisfy the given condition;

sin² t + cos² t = 1;

i.e (.6)² + (.8)² = 1

.36 + .64 = 1.

1 = 1; True.

Ultimately, the statement that t can take values such that sin t= .6 and cost=.8 is True.

The figure below shows a shed in the shape of a rectangular prism.
Note that the shed has a floor.

Answers

Answer:

Step-by-step explanation:

a). Volume of a rectangular prism = Length × width × height

                                                        = 13 × 8 × 12

                                                        = 1248 cubic ft

     Surface area of a rectangular prism = (lb + bh + hl)

     Here, l = length, b = width and h = height of the rectangular prism

     Surface area of the given prism = (13×8 + 8×12 + 12×13)

                                                           = 356 square ft

b). If the shed is made of metal,

    Metal needed to make the shed = Volume

c). The shed is used for the storage.

    Measure would be used → Surface area

Solve using law of sines, find the area of wxy.

Answers

Answer:

area = 828.27 cm²

Step-by-step explanation:

add a line from X, perpendicular to WY, call this point A.

angle Y = 180 - 33 - 121 = 26 degrees

sin 26 = XA/49

0.4384 = XA/49

XA = 21.48 which is the height of the triangle

cos 26 = YA/49

0.8988 = YA/49

YA =  44.04

tan 33 = 21.48/WA

0.6494 = 21.48/WA

WA = 33.08

YW = 77.12

(YW)(XA)(0.5) = area

(77.12)(21.48)(0.5) = area = 828.27 cm²

Step-by-step explanation:

using soh-cah-toa, you can determine that the x and the value given are sin(theta). Sin is opposite over hyp.

thus,

[tex]sin(theta) = 17 \div 19[/tex]

[tex]theta = {sin}^{ - 1} (17 \div 19)[/tex]

once you solve that you get the angle x equals to 63.4746 which can be rounded to 63.5°

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1

Answers

Answer:

The given equation has TWO positive integer valued solutions, {6, 7}

Step-by-step explanation:

Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.

(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.

Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).

Next we focus on (x^2 - 13x + 42).  The discriminant is b^2 - 4(a)(c), or

169 - 168, or 1.  Again we see that there are two real, unequal roots:

      +13 ± √1                  +13 ± 1

x = ---------------  or  x = -------------

             2                            2

OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).

The given equation has TWO positive integer valued solutions, {6, 7}

Bags of sugar come in 3 sizes:

Small bag: A 250 g bag costs 95p.
Medium bag: A 500 g bag costs £1.80.
Large bag: A 3 kg bag costs £3.70.

Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments

Answers

Answer:

Medium

Step-by-step explanation:

The computation is shown below:

The cost for the small and medium bag is shown below:

As we know that

1kg = 1000g

So 3kg = 3000g

Now for small bags

= 0.95 ÷ 250 × 3000

= £11.40

For medium bags

= £1.80 ÷ 500 × 3000

= £10.80

So here the medium bag would represent the better value

5x + 50 = 180

Subtract 50 from both sides

5x = 130

Divide each side by 5

x = 26
