Answer:

Fuel efficient vehicles

Step-by-step explanation:

Since energy costs began increasing in 1970s, a major shift in building practices is the use of more Fuel efficient vehicles. In the 1970s the rise in the cost of energy made most vehicle users to start using smaller vehicles instead of Larger vehicles because smaller cars consume less energy. the effect of this shift caused a structural unemployment in the car manufacturing industry

Answer:

d, b, e

Step-by-step explanation:

Our first prism has a volume of 64, and 1/2 of that would be 32. To calculate volume, we multiply the length times width times height. Option d has the numbers 4 times 4 times 2, which equals 32. Option b has the numbers 8 times 4 times one which equals 32. Finally, option e has the numbers 8 times 2 times 2 which is also 32 thus these 3 are your answers

Answer:

B = 15

Step-by-step explanation:

Combine multiplied terms into a single fraction

6 + 2b/5 = 12

Subtract 6 from both sides

6 + 2b/5 (-6) = 12 (-6)   = 2b/5 = 6

Multiply all terms by the same value to eliminate fraction denominators

2b/5 ( x 5) = 6 (x 5)

Simplify

2b = 30

Step-by-step explanation:

Applying Pythagoras theorem ,

[tex]{24}^{2} = {11}^{2} + {x}^{2} \\ 576 = {121} + {x}^{2} \\ {x}^{2} = 576 - 121 \\ {x}^{2} = 455 \\ x = \sqrt{455} \\ x = 21.33[/tex]

Answer:

A. Major Axis

Step-by-step explanation:

Red line shows the Major axis of the ellipse drawn.

A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane.

An ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.

An ellipse uses two axis, major and minor.

Major axis is the larger one and minor axis is smaller.

The minor axis of an ellipse is the line that contains the shorter of the two line segments about which the ellipse is symmetrical

Now we come to the question.

Here extreme points of the red line are on the ellipse are more distant than the extreme points of the axis perpendicular to the red line.

Therefore, red line shows the Major axis of the ellipse drawn.

Answer:

C

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept

First, find the slope by doing the change in y divided by the change in x for the two points. This would be [tex]\frac{2-(-3)}{0 - 20} = -\frac{5}{20} = -\frac{1}{4}[/tex]. m = -1/4 in the equation.

So far, the equation is y = -1/4x + b

This means the slope is -1/4. Since it give you the y intecept, (0, 2), you know that b is 2 and the equation would be C. y = -1/4x + 2

"We know that for any two inverses f(x) = g(y), meaning that if we take f(x) for any x in the domain of f(x), then g(y), where y is the outcome of f(x), should output x." That is how you test to see if two functions are inverses.

Answer:

The length of the actual ship is 125 meters.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling for example, when representing geographic locations on a map.

A model ship is built to a scale of 1 cm: 5 m. This means that each centimeter of the model represents an actual length of 5 m.

The length of the model is 25 cm, thus the real ship has a length of 25*5 = 125 m.

The length of the actual ship is 125 meters.
