Brett wants to paint the exterior of his two-story home but does not know what length ladder he should buy. The top of his roof is 29 ft above ground level, and (for safety reasons) the ladder should not be at more than an 80° angle from the ground. How long, rounded up to the nearest foot, is the shortest ladder that Brett should buy?

Answers

sin80˚= 29/x; x= 29.44
so after rounding is 30 ft

Answer:

Brett should buy a ladder of minimum 30 ft length.

Step-by-step explanation:

Brett wants to paint his exterior of a double story home.

Height of the roof of the second story from the ground = 29 feet

Maximum angle between the ground and the ladder should be = 80°

Now from the figure,

sin 80° = [tex]\frac{AB}{AC}[/tex]

0.9848 = [tex]\frac{29}{AC}[/tex]

AC = [tex]\frac{29}{0.9848}[/tex]

AC = 29.45

≈ 30 ft

Therefore, Brett should buy a ladder of minimum 30 ft length.

The volume of a fish tank is 20 cubic feet. If the density is 0.2 fish over feet cubed, how many fish are in the tank? (1 point)

Answers

density of fish = number of fish / volume

0.2 = n / 20

n = 20*0.2 = 4

there are 4 fish in the tank.

Answer : The number of fish present in the tank are, 4 fish.

Step-by-step explanation :

As we are given that the volume of a fish tank is 20 cubic feet and density is 0.2 fish over feet cubed.

Now we have to determine the number of fish in the tank.

As, in 1 cubic feet tank the number of fish present in tank = 0.2 fish

So, in 20 cubic feet tank the number of fish present in tank = 20 × 0.2 fish

= 4 fish

Therefore, the number of fish present in the tank are, 4 fish.

When 23 is subtracted from 4 times a certain number the result is 4

Answers

If we say:
x = the 'certain number' we want to find
Then, we can formulate an equation:
4x - 23 = 4
Now, solve for x:
4x = 27
x = 27/4 = 6.25

Let the unknown number be x.

Given,

4x - 23 = 4

4x = 27

x = [tex] \frac{27}{4} [/tex] = 6.75

Hence, the number is 6.75

Find the derivative of f(x) = (1 + 6x2)(x − x2) in two ways.

Answers

Using product rule;

f(x)=(1+6x²)(x-x²)

f'(x)=(12x)(x-x²) + (1-2x)(1+6x²) = 12x² -12x³ +1 +6x² -2x -12x³ = -24x³ +18x² -2x +1

Solving the bracket first;

f(x)=(1+6x²)(x-x²) = x -x² +6x³ -6x^4

f'(x)= 1 -2x +18x² -24x³ = -24x³ +18x² -2x +1

The surface area of the rectangular prism is 158 square feet.

What is surface area?

The surface area of any given object is the area or region occupied by the surface of the object.

Formula for finding the surface area of rectangular prism:

Surface Area = 2{(h × l) + (h × w) +(l × w)]

Where,

l is the length of the rectangular prism

h is the height of the rectangular prism

w is the width of the rectangular prism

According to the given question

Length of the rectangular prism = 8 feet

width of the rectangular prism = 3feet

height of the rectangular prism = 5 feet.

Therefore,

the surface area of the rectangular prism = 2[(8 × 5)+ ( 5 × 3) + ( 8 × 3)]

surface area of rectangular prism = 2[ 40 +15 +24} = 158 square feet.

Hence, the surface area of the rectangular prism is 158 square feet.

How do you solve and graph a piece wise function and state the domain and range?

Answers

for 3) check the picture, on the right-hand-side

now for 4) check the picture on the left-hand-side

if you notice the intervals, it goes from -∞ and stops at -2, then goes from 2 over to 3, then from 3 onwards, so the domain will also be (-∞ , +∞).

Now, the range...

the 1st subfunction 3-x is just a line coming down form -∞....

the 2nd subfunction is just 2x, also a line going up, now once you get to

the 3rd subfunction is just 5, meaning y = 5, or f(x) = 5, which is just a horizontal line at y = 5.

since the 3rd subfunction goes from x > 3 onwards to +∞, and is just a horizontal line, it doesn't go below 5, so one would think the range is -∞, 5.

however, from the 2nd subfunction if we use say x = -1.9999, 2x ---> 2(-1.9999) = -3.9998 , that's lower than 5, and that's the lowest the piece-wise goes, thus, the range comes from -∞ and goes as low as -3.9998, (-∞ ,-3.9998]

notice, we didn't use -2, because the 2nd subfunction 2x, doesn't include it in its range -2 < x ⩽ 3.

now, for 4) I used -1.9999 but your teacher might be expecting something like -1 or thereabouts, just an integer amount. But the idea being, the 2nd subfunction, does not include the -2.

c. 4(cos 90° + i sin 90°)
d. 4(cos 180° + i sin 180°)

Answers

In analytical geometry, there are two types of roots: real roots and complex roots. Imaginary roots are those with the term 'i'. These are complex numbers that can be found on the number line, thus they are called imaginary. The term 'i' is equal to the expression √(-1). So when you solve these equations, just treat the complex numbers as is they are variables.

The only way to solve these is to test each choice such that its final answer would be 4i. These are important equivalents to know:

sin 0° = 0 cos 0° =1
sin 90° =1 cos 90° =0
sin 180° =0 cos 180° = -1
sin 270° = -1 cos 270° = 0

Using these values, let's simplify each choise.

A. 4(1 + i (0)) = 4
B. 4(0 + i (-1)) = -4i
C. 4(0 + i (1)) = 4i
D. 4((-1) + i (0)) = -4

The answer is C.

Final answer:

The complex number 4i in polar form is 4(cos 90° + i sin 90°), which matches choice (c). The magnitude is 4, and the argument is 90° since 4i lies on the positive imaginary axis.

Explanation:

To convert the complex number 4i to polar form and express the argument in degrees, we should consider the general polar form of a complex number which is r(cos θ + i sin θ), where r is the magnitude (modulus) and θ is the argument of the complex number. The complex number 4i has a real part of 0 and an imaginary part of 4. Therefore, its magnitude is 4 and it lies on the positive imaginary axis. In the complex plane, this corresponds to an angle of 90° or 270° from the positive real axis. Since it is on the positive imaginary axis, the correct angle is 90°.

The correct polar form of the complex number 4i is 4(cos 90° + i sin 90°), which corresponds to choice (c).

Each side is an isosceles trapezoid, so ED=2 since you would need to add 2 to each end of the bottom line to get the top line. Now use Pythagorean Theorem to get ED^2+AD^2=AE^2. Plug in your numbers to solve for AE. This is the height of each trapezoid. Then use your formula for the area of a trapezoid, (B1+B2)h/2, to get the area of each side, then multiply by 4 to get the lateral area since there are 4 sides. Remember lateral area is just the sides, then surface area is when you include the area of the two bases.

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given 4 trapeziums with parallel sides :

[tex]a=8\ km\\b=4\ km[/tex]

For height 'h'. we will consider the right angled triangle with

Perpendicular = 4.3 km and base = 2 km ,

We need to find the hypotenuse:

[tex]H^2=B^2+P^2\\\\H^2=2^2+4.3^2\\\\H^2=4+18.49\\\\H=\sqrt{22.49}\\\\H=4.742\ km[/tex]

Now, Lateral surface area of the figure = 4 × Area of trapezium

[tex]4\times \frac{1}{2}\times (8+4)\times 4.742\\\\=113.81\ km^2\\\\=114\ km^2[/tex]

Hence, Option 'D' is correct.

The expression 0.01E+0.003E^2 gives the thickness in millimeters (mm) of the insulation needed for a high voltage cable. E is the number of kilovolts carried by the cable. What thickness of insulation material is needed for 7 kilovolt cable?

Answers

To determine the thickness of the insulation, we need a function that would relate the thickness of the insulation to the kilovolt carried by the cable since it is the only value that is given here. From the problem statement, we are given the function which is T = 0.01E + 0.003E^2. To determine the thickness, we simply substitute the value of the kilovolt to the function and solve for the value of T. We do as follows:

T = 0.01E + 0.003E^2
T = 0.01(7) + 0.003(7)^2
T = 0.217 mm

Therefore, the thickness of the insulation needed would be 0.217 mm.

Answer: 0.217 mm
