Trigonometry Practice

Answer:

The answer is "31.888".

Step-by-step explanation:

When their respective angles were congruent or their side lengths have a constant relation, they know that two quadrilaterals are similar

FGHI is similar to JKLM because of quadrilateral

[tex]\to \frac{FG}{JK} =\frac{GH}{KL}=\frac{HI}{LM}=\frac{FI}{JM}\\\\\to \frac{GH}{KL} =\frac{HI}{LM}\\\\\to \frac{7}{KL}= \frac{9}{41}\\\\\to KL=\frac{7 \times 41}{9}=31.888\\\\[/tex]

Answer:

g(1)=2

Step-by-step explanation:

g(1)= 1^2+1 (you fill in 1 for x)

g(1)=1+1 (1 to the second power is 1 times 1 which is 1 and then you add 1 and 1)

g(1)=2

Answer:

Step-by-step explanation:

1 in = 2.54 cm

Part (a)

Answer: 8.268 in

Part (b)

Answer: 11.693 in

Part (c)

In SI units standard-sized paper is 21.0 cm by  29.7 cm, which is equivalent to 8.268 in by 11.693 in.

Answer: 8.268 in by 11.693 in.

Part (d)

The U.S sized standard paper is 8.0 in by  11.0 in. Therefore the SI (internationally) sized paper is longer.

Part (e)

If the U.S> adopts the SI standard for letter-sized paper, both the width and length of standard paper will have to be increased. Therefore letter-sized paper will occupy a larger area and will be heavier if the thickness and density do not change.

Answer:

£125000

Step-by-step explanation:

Original cost of house = £100 000

Percent increase = 25%

Increase in price = 25% of 100,000

Increase in price = 0.25 * 100,000

Increase in price = 25000

New cost = original cost + Increment

New cost = 100,000 + 25,000

New cost = 125,000

Hence it now cost  £125000

Answer:

a. 33 sqft

Step-by-step explanation:

The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles

Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)

The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24

The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9

Total area is sum of these two or 24 + 9 = 33

Answer:

-30

Step-by-step explanation:

[tex]\frac{N}{-3} -2 =8[/tex] ( Add 2 on both sides)

[tex]\frac{N}{-3} = 10[/tex] ( Multiply by -3 on both sides)

[tex]N = -30[/tex]

Verify:

[tex]\frac{-30}{-3} =10[/tex] (Correct)

Answer:

[tex] \frac{n}{ - 3} - 2 = 8 \\ \frac{n}{ - 3} = 8 + 2 \\ = 10 \\ n = 10 \times - 3 \\ n = - 30[/tex]

Answer:

3

Step-by-step explanation:

8-5= 3

11-8= 3

14-11= 3

Answer:

common difference = difference between two consecutive number in a given series

hence,

8-5=3

common difference =3

Answer:

Answer:

3

Step-by-step explanation:

3x-3=2x

3x-2x=3

x=3

Answer:

x=3

Step-by-step explanation:

3x - 3 = 2x

-3x -3x

-3 = -x

The x cannot be a negative so you divide both sides by -1 and then the answer becomes x=3

Answer:

it has 5 hopefully this helps you with work

Answer:

Step-by-step explanation:

Given lines:

These have same slopes of 2/3 and therefore are parallel, so no intersection. There is no solution if lines don't intersect.

The graph is attached as well to show lines are parallel.

Answer: b = 14.

Step-by-step explanation:

We have the function:

f(x) = x^2 + b*x - 21

The minimum of a quadratic function will be at the vertex, and the vertex is at the value of x such that:

f'(x) = 2*x + b = 0

then the vertex is at:

x = -b/2

Then the minimum of the function f(x) will be:

f(-b/2) = (-b/2)^2 + b*(-b/2) - 21

and we know that the minimum value is -70, then:

f(-b/2) = -70 = (b^2)/4 - (b^2)/2 - 21

Now we need to solve this equation for b.

-70 = (b^2)/4 - (b^2)/2 - 21

-70 = -(b^2)/4 - 21

-70 + 21 = -(b^2)/4

49 = (b^2)/4

49*4 = b^2

196 = b^2

√196 = b = 14

The value of b is 14.

Answer:

it's 11

Have a good day!!

Answer:

35 years

Step-by-step explanation:

Given that:

Current deer population, P0 = 800

Growth rate = 20% yearly

For the population to double in size, P = 2 * P0 = 2 * 800 = 1600

t = number of years

Using the relation :

P =P0(1 + r)^t

1600 = 800(1 + 0.2)^t

1600 / 800 = (1.02)^t

2 = (1.02)^t

t = log2 / log(1.02)

t = (0.3010299 / 0.0086001)

t = 35.003069

t = 35 years

Answer:

3.8

Step-by-step explanation:

Answer:

76.53 cm

Step-by-step explanation:

From the question, the triangle formed has 2 sides and an included angle ;

Angle, θ = C = 45°

We use cosine rule :

Taking the side to find as c

a = 100 ; b = 100

From cosine rule :

c = sqrt(a² + b² - 2abCosC)

c = sqrt(100² + 100² - 2(100*100)Cos45

c = sqrt(10000 + 10000 - 20000 * 0.7071067)

c = sqrt(20000 - 14142.135)

c = sqrt(5857.865)

c = 76.536690

c = 76.53 cm

Answer:

A. Frozen yogurt

Step-by-step explanation:

The frozen yogurt costs less than the frozen custard, even though you get the same amount (3 ounces)

No matter how much money Marco has, he would be able to buy more of the frozen yogurt because it has a cheaper unit rate.

So, the answer is A, frozen yogurt
