The area of each part of the figure is Triangle B = 10 square units and Triangle A = 17.5 square units. The area of the whole figure is 27.5 square units.

A two-dimensional surface, like the surface of a shape or object, can be measured in terms of area. Usually, it is expressed in square quantities like square metres (m2) or square feet (ft2). By multiplying the length and breadth of a rectangle, or by applying particular formulas for other forms, such as base times height divided by two for a triangle, one can determine the area of a shape.

From the given figure we observe that the base of the slanted figure has true base length of 5 units.

Thus, for triangle B the area is:

Triangle B = 1/2(b)(h)

Triangle B = 1/2(5)(4) = 10 square units.

For triangle A we have:

Triangle A = 1/2(5)(7) = 35/2 = 17.5 square units.

The area of the whole figure is:

A = 10 + 17.5 = 27.5 square units.

Hence, the area of each part of the figure is Triangle B = 10 square units and Triangle A = 17.5 square units. The area of the whole figure is 27.5 square units.

By using dimensional analysis we find the following two results:

a) 0.30 m = 0.984 ft

b) 150 km / h = 1.554 mi / h

In this problem we must find a quantity of a given unit that is equivalent to another value of another unit of the same kind. For instance, we must look up for the quantity in a unit length equivalent to another quantity in another unit length. Now we proceed to obtain all the equivalencies by simple rule of three:

a) 0.30 m × (1 ft / 0.3048 m) = 0.984 ft

b) 150 km / h × (1 mi / 1.609 km) × (1 h / 60 min) = 1.554 mi / h

Answer:

yes i think thats right

Step-by-step explanation:

if not then it might be b

the height will be 50 ft after 0.575 seconds and after 5.424 seconds.

The equation that models the height is:

h(t) = 96*t - 16*t^2

Here we want to find the time such that the height is 50ft, then we need to solve the equation:

h(t) = 50 = 96*t - 16*t^2

Now we can solve that for t, we have the quadratic equation:

50 = 96*t - 16*t^2

0 = -16*t^2 + 96*t - 50

Then the solutions are:

t = (-96 ± √(96*96 - 4*(-50)*(-16))/(2*-16)

t = (-96 ± 77.6)/(-32)

The two solutions are:

This means that the height will be 50 ft after 0.575 seconds and after 5.424 seconds.

Out of the population being surveyed, the one that could result in a sample statistic but not a parameter is; B: 50

A sample statistic is a piece of information you get from a fraction of a population.

A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean).

Now, we are told that a population consists of 5000 people. This means that the sample statistic could be the sample mean which could be 50 but certainly not 5000 as the sample statistic can't be same as the population.

The value of  dy/dx at x = 1 is  mathematically given as

dy/dx=5-1.8898i

This is further explained below.

Generally, Given that cost y of producing x gallons ag an implicit evaluation

y^2-10 x y=200

Differentiate the above equation as

[tex]\begin{aligned}&2 y y^{\prime}-10 y-10 x y^{\prime}=0 \\&y^{\prime}(2 y-10 x)=10 y \\&y^{\prime}=\frac{10 y}{2 y-70 x}=\frac{5 y}{y-5 x}\end{aligned}[/tex]

when x=1, substitute in the given equation to get y value

y^2-10 y=200

or

y=5+13.2288i

y=5−13.2288i

y represents the cost and hence cannot be negative Hence practical solution for y is y=5+13.2288i substitute in the ' y ' equation to get [tex]$\frac{d y}{d x}$ at $x=1$[/tex]

when x=13 y=5+13.2288i

Hence

d y/d x at x=1 will be

dy/dx[tex]=\frac{5(5+13.2288i)}{5+13.2288i-5}[/tex]

[tex]dy/dx=\frac{25+66.144}{13.2288i}[/tex]

Winter would last for 14,600 days

Planet can be described as celestial bodies that move around the sun. The earth and Neptune are typical examples of planets. There are 8 planets in the solar system.

Other planets have different seasons same way as Earth

Neptune's season last for 40 years

Therefore the number of days that winter would last can be calculated by multiplying the number of years which is 40 by the number of days in a year which is 365

1 year is 365 days

Since it 40 years then we multiply by 365

= 365 × 40

= 14,600

Hence Winter would last for 14,600 days

The reasonable domain for this function is [tex](x > 0)[/tex] .

The collection of all feasible values for the independent variable is referred to as a function's domain.

When we substitute different values for the independent variable from the domain, the dependent variable's range refers to the set of all conceivable values for that variable.
