Answer:

-39192

Step-by-step explanation:

y= -4x^2 +8x+8

Let x = 100

y= -4(100)^2 +8(100)+8

= -4(10000)+800+8

=-40000+808

= -39192

a chord subtend an angle of 72⁰ at the center of a circle with radius 24.5m. calculate the perimeter of the minor segment

andre [41]

The perimeter of the minor segment is 77. 4m

<h3>How to determine the perimeter</h3>

The formula for determining the perimeter of the minor segment is given as;

Perimeter = θ/360 × 2πr + 2r sin θ/2

where;

radius = 24. 5m

θ = 72

Substitute into the formula;

Perimeter = (72/360 × 2 × 3. 142 × 24. 5) +( 2 × 24. 5 × sin 72)

Perimeter = 30. 79 + 46. 60

Perimeter = 77. 4 m

Thus, the perimeter of the minor segment is 77. 4m

To safely cross a bridge, the most a delivery truck can weigh is 4 tons. The empty truck and driver weigh a total of 5,690 pound

brilliants [131]

Answer:

Truck can safely carry <em>2310 pounds </em> of cargo.

Step-by-step explanation:

Given the safety limit of weight to cross the bridge safely is 4 tons.

1 ton is equal to 2000 pounds.

so, 4 tons are equal to 2000 $\times$ 4 = 8000 pounds

Now, given that

weight of empty truck and driver = 5690 pounds

To find:

Weight of cargo that the truck can safely carry ?

Solution:

Total weight of the truck is actually the combined weight of the empty truck, the drive and the cargo carried in it.

So, Total Weight allowed = 8000 pounds = 5690 pounds + Weight of Cargo

Weight of Cargo = 8000 - 5690 pounds

Weight of Cargo = <em>2310 pounds</em>

Truck can safely carry <em>2310 pounds </em> of cargo.
