Answer:

72.26 cm²

total area = 145.49 cm²

small tri = 12.99cm²

large tri = 23.38 cm²

so shaded area = 145.49 -(2x12.99)-(2x23.88)=72.26cm²

Answer:

1. sin and cos  2. complementary  3. sinA = cosB  4. 80°  5. 17

Step-by-step explanation:

1. cofunctions: having the same value at complementary angles

sin θ = cos (90 - θ), or  cos θ = sin(90 - θ)

2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°

one of the angle in a right triangle must be a right angle = 90°

180°(sum of angles of a triangle) - 90° = 90°(the sum of the other two angles) => which is complementary

3. sinA = cosB

4. cos θ = sin(90 - θ)

=> cos 10° = sin(90 - 10°)

=> cos 10° = sin(80°)

5. sin θ = cos (90 - θ)

=> sin 73° = cos (90 - 73°)

=> sin 73° = cos (17°)

Answer:

a= 10 b= -13 c= -3

Step-by-step explanation:

First, you multiply 5x+1 and 2x-3

You then end up with 10x^2-13x-3 which is in ax^2+bx+c form

So, a would be 10, b would be -13, and c would be -3.

Answer:

D

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = [tex]\sqrt{2080}[/tex]

c = 45.61

The answer is 45.61 units.

The average speed of the car for the given distance is 91.97 km/hr.

While both speed and velocity are indicators of how quickly an object is travelling, they serve different purposes. The distance travelled in a given amount of time, independent of direction, is referred to as speed, which is the magnitude of the velocity vector. In contrast, velocity is a vector quantity that accounts for both speed and direction. It is measured in units of distance per unit of time in a particular direction and is defined as the rate of change of position of an item with regard to a frame of reference.

Given that, a car started 35 minutes later that is it started after:

35 minutes = 35/60 = 0.5833 hours

Now the distance is given as:

distance = speed x time

Now, for speed = 65 km/hr:

distance = 65t

For the car the time is (t - 0.5833) thus:

distance = speed x time

130 = speed x (t - 0.5833)

Now for speed we have:

30 = s x (t - 0.5833)

130 = st - 0.5833s

130 + 0.5833s = st

130/s + 0.5833 = t

Now, substituting the value of t in the equation of the van we have:

distance = 65t

distance = 65(130/s + 0.5833)

130/s + 0.5833 = distance/65

130/s + 0.5833 = distance/65

130/s + 0.5833 = 130/65

130/s + 0.5833 = 2

s = 91.97km/hr

Hence, the average speed of the car for the given distance is 91.97 km/hr.

Answer:

f(-3) = 6

Step-by-step explanation:

This question asks one to evaluate the function (f) for input (-3). It is known that the x-axis represents the input, while the y-axis represents the output. Therefore, find (-3) on the x-axis, and then see where the graph of the line is when it meets the value (-3), this value will be the output. In this case, the output is (6).

Answer:

8.25 kg

Step-by-step explanation:

Given that,

Weight of Apples = 3 3/4 kg

Weight of guava = 4 1/2 kg

Total weight of fruits = weight of apples + weight of guava

[tex]=3\dfrac{3}{4}+4\dfrac{1}{2}\\\\=\dfrac{15}{4}+\dfrac{9}{2}\\\\=8.25\ kg[/tex]

So, the total weight is equal to 8.25 kg.
