Answer:

12 miles

Step-by-step explanation:

Alyssa takes part in the triathlon. She cycles 4/5 of the route, runs 1/8 of the route, and swims the rest of the way. She swims 0.9 miles. Find the total distance of the triathlon route.

Total distance Alyssa cycled and ran =

[tex]\frac{4}{5} + \frac{1}{8}[/tex]

[tex]\frac{32 + 5}{40}[/tex] = [tex]\frac{37}{40}[/tex]

Distance she swam =  1 - 37/40 = 3/40

3/40 of the distance is 0.9

the total distance = 40/3 x 0.9 = 12 miles

Just need to put zero instead of y and solve the equation for find the value of x :

0 = 2 Cot ( x/4 )

Cot ( x/4 ) = 0

Cot ( x/4 ) = Cot ( π / 2 )

x / 4 = π / 2

x = 4 × π / 2

x = 2π

Thus the correct option is C .

Answer:

92

Step-by-step explanation:

Since 92 is the answer, we need to factor out 92

Ex: 1, 2, 4, 23, 46 and 92

1 x 92

4 x 23

Answer:

The submarine moves 4 units right and 6 units down to get to its current position

Step-by-step explanation:

Given

[tex](x,y) \to (x + 4, y - 6)[/tex]

Required

Describe the movement of the submarine from the initial to the current position

The rule of translation is as follows:

[tex]x \to x + a[/tex] --- This implies right translation by a units

[tex]y \to y -b[/tex] --- This implies down translation by b units

So, we have:

[tex]x \to x + a[/tex]

[tex]x \to x + 4[/tex]

By comparison;

[tex]a =4[/tex]

[tex]y \to y -b[/tex]

[tex]y \to y - 6[/tex]

By comparison:

[tex]b = 6[/tex]

Hence, the submarine moves 4 units right and 6 units down to get to its current position

1=79

the answer is 79

Answer:

x^4 - 2.2x^2 - 4

Step-by-step explanation:

Given the following

R(x) = 2x4 – 3.2x^2 + 2x – 1 and C(x) = x4 – x2 + 2x + 3

Required

P(x)

Since P(x) = R(x) – C(x).

P(x) =   2x4 – 3.2x^2 + 2x – 1 – (x^4 – x^2 + 2x + 3).

Expand

P(x) = 2x4 – 3.2x^2 + 2x – 1 – x^4 + x^2 - 2x - 3

P(x) =   2x4 - x^4 - 3.2x^2 + x^2 + 2x - 2x -1 - 3

P(x) = x^4 - 2.2x^2 - 4

Hence the profit function is  x^4 - 2.2x^2 - 4

Answer:

Step-by-step explanation:

THe formula for calculating midpoint is expressed as;

M(X, Y) = {(x1+x2/2), y1+y2/2}

Given

Midpoint = (2, 5)

K = (8, 7)

Required

Coordinate of M

X = x1+x2/2

2 = 8+x2/2

4 = 8+x2

x2 = 4-8

x2 = -4

Similarly;

Y = y1+y2/2

5 = 7+y2/2

10 = 7+y2

y2 = 10-7

y2 = 3

Hence the coordidates of M is at (-4,3)

84848488ti

Step-by-step explanation:

................

Answer:

84848488 is the answer

Answer:

the answer is C .............

The area of a circle is the radius squared x pi.

Area = r^2 x pi

R is the radius which is half the diameter.

Diameter = 102 inches

Radius = 102/2 = 51 inches

Area = 51^2 x pi

Area = 2,601pi inches^2 ( in terms of pi) or

Area = 8,167.14 inches^2

Area of circle is 8,167.14 cm ²

We have

diameter of circle = 102 cm

And we need to find area of circle,

So the formula we using is

Area of circle = π ×r ²

Here,

R denotes for Radius

π denotes for pi.

For finding area of circle we need to find radius

here we have diameter of circle = 102 cm and

We know that ,diameter is the double of radius it means radius is the half of diameter

So, radius of circle = 102/2 = 51 cm

Now Solve it

Area of circle = π × ( r ) ²

Substitute the value

Area of circle = 3.14 × ( 51cm )² .. [ using π = 3.14 ]

Multiply the values

Area of circle = 3.14 × ( 51 cm × 51cm) ..[( 51 ) ²= 51 × 51]

Area of circle = 3.14 × 2,601 cm².

Therefore , Area of circle is 8,167.14 cm ²

Answer:

4 /15

Step-by-step explanation:

From the number cube :

Count of Numbers greater than 4 = 16

Sample space of number cube = 20

P(number greater than 4) = 16 / 20 = 4/5

Word : ATTENTION

Count of letters in attention = 9

Count of T's in attention = 3

P(choosing T) = 3 / 9 = 1/3

P(greater than 4, then T) = 4/5 * 1/3 = 4 /15

Answer:

11. 26

12. 111

Step-by-step explanation:

_____________

Answer:

11:

since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111
