The value of sin2 Θ is in the 4th quadrant is -24/25

Explanation:

Given the expression of cosΘ= 3/5 with Θ in quadrant 4;

According to SOH, CAH TOA;

cosΘ= adjacent/hypotenuse

Get the opposite

5² = opp² + 3²

opp²  = 25 - 9

opp² = 16

opp = 4

SinΘ = opp/hyp

SinΘ = 4/5

Sin2Θ = 2sinΘ cosΘ

Sin2Θ = 2(-4/5)(3/5)

Sin2Θ = -24/25

Hence the value of sin2Θ is in the 4th quadrant is -24/25

Answer:

y = -1x+2

Step-by-step explanation:

(1,1)(7,-5)

y2-y1/x2-x1 = slope

-5-1/7-1 = -6/6= -1

y-y1 = slope(x-x1) // equation formula

y-1=-1(x-1)

y = -1x + 1 +1

y = -1x+2

Answer:

y = 3x - 4

Step-by-step explanation:

a line parallel to another will have the same slope, just a different y-intercept or b-value. Using this, we suggest the equation of the question [tex]y = 3x + b\\[/tex], as we can solve for b. The point (4,8) was given, which means that an input of 4 as x returns 8 as y. Thus, [tex]8 = 3(4) + b[/tex]. Solving this gains b = -4

The dimensions that would maximize the area enclosed by the fence is 30m × 60m.

where

l = length

w = width

Therefore,

The corral uses the side of a barn as one of its sides, so the fencing is required on three sides of the rectangular region. Therefore,

perimeter = L + 2w

L + 2w = 120

L = 120 - 2w

area = Lw

area = (120 - 2w)w

area = 120w - 2w²

area = -2w² + 120w

We have a quadratic equation and it is parabolic.  The leading coefficient is negative. Therefore, the parabola opens downward and the vertex is the maximum point.

The area is maximized at the vertex. Therefore,

To find the vertex, we need to have our quadratic equation in general form,

ax² + bx + c = 0

so a = -2, b = 120

w = -b / 2a

w = - 120 / 2 × -2

w = -120 / -4

w = 30

Therefore,

area = -2(30)² + 120(30)

area = 1800m²

Therefore, the maximum area we can enclose is 1800 m², the width is 30m, then the length will be 60 m because 60 × 30 = 1800 m².

Answer:

y = 6.20 + 12.4(x - pi/4)

Step-by-step explanation:

dy/dx = 2e^x secx + 2e^x secx * tanx= 2e^x secx (1 + tanx)

At x = pi/4, use sec(pi/4) = [tex]\sqrt{2}[/tex]. tan(pi/4) =1

so dy/dx = 2e^(pi/4) * [tex]\sqrt{2}[/tex] * (1 + 1) = [tex]4 \sqrt{2} e^{\pi/4}[/tex] ≈ 12.4 (This is the slope of the tangent line)

When x = pi/4, y =  2e^(pi/4) * [tex]\sqrt{2}[/tex]  = [tex]2 \sqrt{2} e^{\pi/4}[/tex]= 6.20

Then the equation of the tangent line is

y = 6.20 + 12.4(x - pi/4)

Answer:

The angle is 59 degrees.

Step-by-step explanation:

A triangle's angles, in total, must equal 180 degrees.

71 + 50 + (6x-1) = 180

71 +50 = 121

121 + (6x-1) = 180

6x - 1 = 59

Subtraction is a mathematical operation that reflects the removal of things from a collection. The yards of ribbon that were bought by Jina is 11 yard.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given that Prepaid credit card amount = $15

Also, She bought some bulk ribbon at a craft store and the price of ribbon was 21 cents per yard.

If after that purchase there was $12.69 left on the card.

Now, we can write the following details,

The amount on the credit card = $15

The amount spend on buying the ribbon = $0.21 cents per yard

The amount left on the credit card = $12.69

Further, we can write,

The amount that was used to buy the ribbon

= $15 - $12.69

= $2.31

Now, the length of the ribbon bought by Jina is,

Length of ribbon =  $2.31 / $0.21 per yard = 11 yards

Hence, the yards of ribbon that were bought by Jina is 11 yard.

The probability of rolling a factor of 9 is 1/2, or 50%.

Step-by-step explanation:

The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.

Simplify 3/6 to 1/2 to get a probability of 50%.

Answer:

The value of the angles are 38° and 52° respectively

Let the acute angles be represented by a and b.

Based in the information given,

a = 2(b - 12)

a = 2b - 24.

Note that the angle in an acute angle equals to 90°.

Therefore,

a = 90 - b.

a = 2b - 24

Equate the equations together

90 - b = 2b - 24

2b + b = 90 + 24

3b = 114

b = 114/3

b = 38

Therefore, a will be:

= 90° - 38° = 52°

The value of the angles are 38° and 52° respectively.

Answer:

hypotenuse ( c²) = a² + b²

- assume you're given the side a, find b:

b² = c² - a²

b² = (34)² - (16) ²

b² = 1156 - 256

b² = 900

b = √ 900

b = 30

therefore, the other leg is 30 inches.

Answer :

30 inches

Step-by-step explanation:

To determine one of the side lengths of a right triangle we can use the Pythagorean formula :

a² + b² = c²

b = 16 in

c = 34 in

a² + b² = c²

a² + 16² = 34²

a² + 256 = 1.156

a² = 1.156 - 256

a² = 900

a = √900

a = 30 in
