Answer 2

Answer:

[tex]860\; \rm ft^{2}[/tex].

Step-by-step explanation:

Each rectangular prism contains six sides.

In this rectangular prism, these sides are:

A set of two [tex]5\; \rm ft[/tex] by [tex]8\; \rm ft[/tex] rectangles. Area: [tex]5\; \rm ft\times 8\; \rm ft = 40\; \rm ft^{2}[/tex] each.A set of two [tex]5\; \rm ft[/tex] by [tex]30\; \rm ft[/tex] rectangles. Area: [tex]5\; \rm ft \times 30\; \rm ft = 150\; \rm ft^{2}[/tex] each.A set of two [tex]8 \; \rm ft[/tex] by [tex]30\;\rm ft[/tex] rectangles. Area: [tex]8\; \rm ft \times 30\; \rm ft = 240\; \rm ft^{2}[/tex] each.

Take the sum of the areas of these six rectangles to find surface area of this rectangular prism:

[tex]\begin{aligned}& 2 \times 40\; \rm ft^{2} + 2 \times 150\; \rm ft^{2} + 2 \times 240\; \rm ft^{2} = 860\; \rm ft^{2}\end{aligned}[/tex].

An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of cats is 3 more than 5 times the number of dogs, how many dogs and cats are currently at the animal shelter?

Answers

Answer:

98 cats and 19 dogs

Step-by-step explanation:

cat = c

dog = d

The animal shelter currently has a total of 117 animals

c + d = 117

c = 117 - d

the number of cats is 3 more than 5 times the number of dogs

c = 3 + 5d

subtitute c

117 - d = 3 + 5d

117 - 3 = 5d + d

114 = 6d

6d = 114

d = 114/6 = 19

so, the cat is 117-19 = 98

Volume = 150.9 cubic units

Explanation:

(First, we need to find the side opposite to 40 degrees)
Let the side be ‘s’
tan(40) = s/6 (Opposite/Adjacent)
tan(40) x 6 = s
s ≈ 5.03 units

Area of triangle base = 1/2 x Base x Height = 1/2 x 6 x 5.03 = 15.09 square units

Substitute x in ( 1 ) :

                         2( 2 - y) - 5y = 5

                             4 - 2y - 5y = 5

The solutions to a quadratic equation are 4 and -8. What is the quadratic equation?

The quadratic equation is x^2 + 4x - 32 = 0

Step-by-step explanation:

x^2 + 4x - 32= 0

Answer:

If the solutions (or roots, or zeros) are -4 and -8 then the factors are (x+4) and (x-8), so the equation would by:

Y=(x+4)(x-8) foil it out.

Y=x(2)+4x-(8)x-6)

Answer:

6/7 or -6/7

Step-by-step explanation:

Pythagoras.

c² = a² + b²

the trigonometric functions in a norm circle (radius = 1) express the side lengths of inscribed right-angled triangles.

sin(x) is one side (e.g. "a") "touching" the 90 degree angle.

cos(x) is the other side ("b") of the 90 degree angle.

and the radius (1) is the Hypotenuse (the side opposite of the 90 degree angle), which is called "c" in the formula of Pythagoras.

so, we have

1² = (sqrt(13)/7)² + b²

b² = 1² - (sqrt(13/7)² = 1 - 13/49 = 49/49 - 13/49 = 36/49

b = cos(x) = sqrt(36/49) = 6/7

as we don't know anything about the angle x except that it has a positive sin(x) value, the cos(x) value can be positive or negative depending on if x is an angle of the first or of the second quadrant in the norm circle.

in the first quadrant cos(x) is also positive, in the second quadrant cos(x) is negative.

the third and fourth quadrants do not apply, as sin(x) would be negative for both.

if y^17-17 is divided by y+1 , the remainder is

Answers

Answer:

Step-by-step explanation:

a) We have 15! as the product of 1 to 15 natural numbers.  Since 17 is prime there will be no factor common to these

By actual division we find

15! (mod 17) =16

From this we deduce

even 16! mod 17 = 16 = -1

According to Wilson theorem

(17-1)! = -1 mod 17

Thus verified 17 is prime

Hence 15! (mod 17) =-1=16

-----------------------

b) 2(26!) is divided by 29

Since 29 is prime

(29-1)! = -1 mod 29

28! = -1 mod 29 = 28

When divided this gives 25 as remainder

Consider the line y=7x-6.
Find the equation of the line that is perpendicular to this line and passes through the point (6, 2).
Find the equation of the line that is parallel to this line and passes through the point (6, 2).

Answers

Answer:

Case 1: 7y + x - 20 = 0 (Perpendicular)

Case 2: y - 7x + 40 = 0 (Parallel)

Step-by-step explanation:

Case 1: Perpendicular

Equation of the given line y = 7x - 6

Comparing with the general equation y = mx + c; m = 7

For two lines to be perpendicular, the product of their gradients is (-1) or we can also say; gradient of one line must be the negative inverse of the other gradient.

So the gradient of a line perpendicular to y = 7x - 6 should be (-1/7)

Now solving for the equation of the line using the formula

y - y = m(x - x ) where (x , y ) are the coordinates of the point.

substituting..

y - 2 = (-1/7)(x - 6)

7(y - 2) = -1(x - 6)

7y - 14 = -x + 6

7y + x -14 - 6 = 0

7y + x - 20 = 0 is the equation of the line perpendicular to y = 7x - 6 and passes through the point (6,2)

Case 2: Parallel

Equation of the given line y = 7x - 6

Comparing with the general equation y = mx + c; m = 7

For two lines to be parallel, they must have equal gradients.

So the gradient of a line parallel to y = 7x - 6 should be 7

Now solving for the equation of the line using the formula

y - y = m(x - x ) where (x , y ) are the coordinates of the point.

substituting..

y - 2 = 7(x - 6)

y - 2 = 7x - 42

y - 7x -2 + 42 = 0

y - 7x + 40 = 0 is the equation of the line parallel to y = 7x - 6 and passes through the point (6,2)

What is the first term for an arithmetic sequence with a12 = 56 and a21=101?

Answers

The first term is -43.

Explanation:

an = a + (n - 1)d

a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation

Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5

Subtitute d into the first equation
a + 99 = 56
a = -43

a refers to the first term, hence the first term is -43.
