The distance between the rock and the surface is 827.20 cm.

Given data,

There is a robot on Mars' surface. 13.33 degrees of depression can be seen between a camera in the robot and a boulder on the surface of Mars. 196.0 cm is how high the camera is from the ground.

How far is the rock from the camera?

From the given data,

tan c = AB/BC

tan 13.33° = 196/BC

BC = 196/tan 13.33°

BC = 827.20 cm

Hence, the distance between the rock and the surface is 827.20 cm.

Answer: 6.25%

Step-by-step explanation:

To find what percent 61 is of 976, we divide 61/976. This comes out to be 0.0625. Multiply by 100 to get your percentage, and it's 6.25%.

Answer:

The answer is    x=2

Step-by-step explanation:

1. Rearrange terms-

29x + 3 (  5 - 35x) = - 119 - 9x

29x + 3 ( - 35x + 5) = - 119 - 9x

2. Distribute-

29x + 3 ( - 35x + 5) = - 119 - 9x

29x - 105x + 15 = - 119 - 9x

3. Combine like terms-

29x - 105x + 15 = - 119 - 9x

- 76x + 15 = -119 -9x

4. Rearrange terms-

- 76x + 15 = - 119 - 9x

- 76x + 15 = - 9x - 119

5. Subtract 15 from both sides-

- 76x + 15 = - 9x - 119

- 76x +15 -15 = -9x - 119 - 15

6. Simplify-

- 76x = - 9x - 134

7. Add 9x to both sides-

- 76x + 9x = - 9x - 134 + 9x

8. simplify-

- 67x = - 134

9. Divide both sides by the same factor-

[tex]\frac{-67x}{-67} = \frac{-134}{-67}[/tex]

10. Simplify-

x = 2

The sum of DE+FG+HI=90 if DE, FG, HI are all parallel to BC and BC=60.

Quadrilaterals with at least one set of parallel sides are referred to as "trapezoid" quadrilaterals. In British and other dialects of English, the word "trapezium" is used.

Euclidean geometry dictates that a trapezoid must be a convex quadrilateral. The base of the trapezoid is referred to by its parallel sides. If the other two sides are parallel, the trapezoid is a parallelogram, and there are two pairs of bases. If not, the other two sides are known as the legs (or lateral sides). Unlike the specific situations below, a scalene trapezoid is a trapezoid where none of the sides have equal lengths.

Given,

ΔABC is a scalene triangle.

And BC=60

DE, FG, HI are all parallel to BC.

From the midpoint-theorem,

DE||BC then,

DE=(1/2)BC

FG||BC

FG=(1/2)BC

HI ||BC

HI=(1/2)BC

DE+FG+HI=(1/2BC+1/2BC+1/2BC)

=(1/2(3BC))

1/2(3(60))

=90

Therefore,

The age of the fossil is 24, 312 years assuming an exponential decay model.

Exponential decay model refers to model in which the amount of something decreases at a rate proportional to the amount left and this rate is given by a constant ratio k. The formula for remaining quantities of a substance is given by:

P = 100 e^(-kt)

Where P is the remaining quantity, k is the constant of decay, and t is time.

As the half life of the carbon 14 is 5700, when 50% of the substance remains,

50 = 100 e^(-5700k)

1/2 = e^(-5700k)

In(1/2) = In(e^(-5700k))

- In (2) = -5700k

k = In(2)/5700 = 0.0001216

Since, 5.2% carbon-14 remains,

5.2 = 100 e^(-0.0001216t)

0.052 = e^(-0.0001216t)

In(0.0052) = - 0.0001216

t = In(0.052) * - 0.0001216

The cube root of unity are found to be 1, -1±i√3/2 and -1±i√3/2.

In order to find the cube root of unity let us say,

x³ = 1

Solving further,

x³-1 = 0

Now,

(x-1)(x²+x+1)=0

For, x-1=0

x = 1.

And,

For, (x²+x+1)

Solving by using quadratic formula,

x = -1±√(-3)/2.

By evaluating the piecewise function we will see that the difference is:

f(1) - f(-7) = 3

Here we have a piecewise function defined on the image, and we want to find the difference:

f(1) - f(-7).

First, let's find these values.

f(1) means that we need to evaluate the function in x = 1.

Notice that the second piece can be used on the domain 4 < x ≤ 1, so we need to use that part.

f(1) = -(1)^2 - 3*1

f(1) =-1 - 3 = -4

To evaluate in x = -7 we need to use the first piece of the function:

f(-7) = |-7 + 5| - 9

f(-7) = |-2| - 9 = -7

Then the difference is:

f(1) - f(-7) = -4 - (-7) = -4 + 7 = 3

The probability of getting 5 black chips and 6 white chips is [tex]\frac{7}{22}[/tex].

What do you mean by probability?

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty.

According to data in the given question,

We have the given information:

Total number of different colored chips = 35

Number of black chips = 20

Number of white chips = 15

And you draw 11 chips at random.

Suppose the number of required month be x.

Then, the inequality expression can be written for the given case as,

432 + 40x > 505 + 32x

⇒ 40x - 32x > 505 - 432

⇒ 8x > 63

If the top slips down the wall at a rate of 2 ft/s, then 3.476 ft/s fast the foot will be moving away from the wall when the top is 10 feet above the ground.

In the given question, a 15 foot ladder is leaning against a wall. if the top slips down the wall at a rate of 2 ft/s.

We have to find how fast will the foot be moving away from the wall when the top is 10 feet above the ground.

As given, 15ft ladder dy/dt= -2y=13ft

Let the length be x and height be y

So from the Pythagorean theorem

x^2+y^2=h^2

Now apply the above formula to get the value

x^2+y^2=15^2

Take the derivative with respect to time

2x * dx/dt+2y*dy/dt=0

dx/dt= -y/x *dy/dt

When y = 13

then x^2+13^2=15^2

x = 7.48

dx/dt= -13/748 * (- 2)

dx/dt= 3.476 ft/s

Hence, if the top slips down the wall at a rate of 2 ft/s, 3.476 ft/s fast will the foot be moving away from the wall when the top is 10 feet above the ground.

The rank of population size from fastest to slowest growth is N = 1250, N = 1500, N = 1000, N = 750, N = 500, and N = 250.

The population growth rate is the measure that helps to determine how much the population size changes over time. The population growth rate shows either logistic growth or exponential growth. The formula for logistic population growth is given by [tex]\frac{dN}{dt}=r_{\text{max}}N\left(\frac{K-N}{N}\right)[/tex]. Here, N is the population size, t is time, r (max) is the maximum rate of increase, and K is the carrying capacity.

The one that grows fast will have a large population size, and the one that grows slowly will have a small population size. To rank the population size, arrange the given population size from the largest to the smallest. As a result, we get,

Fastest growth rate N=1250, N=1500 , N=1000, N= 750, N= 500, N= 250 Slowest growth rate
