I am not sure how to solve this. I have tried many times.

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:

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:

326

359 + 440 + 417 = 1216

(440/1216) × 900 = 326

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.

A=54

2. A=1/2x6(12+4

A=48

Answer:

x = 112

Step-by-step explanation:

1/8x + 2 = 16

Subtract 2 from both sides

1/8x = 14

Multiply both sides by 8

x = 112

Answer:

x= $6.90

Answer: Part A: 3 (yards per second) Part B: 20 (seconds)

Step-by-step explanation:

See answer above :)

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:

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.

volume = area of the base × the height

[1/2×(2+2)×6] × 8

= 1/2×24×8

= 24×4

= 96 ft³

Answer:

180 ft³

Step-by-step explanation:

Total volume = base rectangular prism + top triangular prism

v = 6 * 8 * 2 + 1/2 (6 * 8 * (5.5 - 2))

v = 96 + 84 = 180

Step-by-step explanation:

Answer:

360 cubic units

Step-by-step explanation:

height = 4 units

length = 10 units

breadth = 6 units

Volume of a cuboid = l × b × h

V = 10 × 6 × 4

V = 10 × 24

V = 240 cubic units

Now a scale factor of 1.5 units is applied to the dimensions,

new volume = 240 × 1.5 = 360

∴ New volume of the prism = 360 cubic units
