Answer:the interest would be $3,500

Step-by-step explanation:  you have to multiply all of the numbers together but change the 3.5% to a decimal of 0.035

Step-by-step explanation:

Area (A) = (1/2)b×h = (1/2)(10)(6) = 30

Perimeter = 8+ 8 + 10 = 26

The surface area of the cone is 36π

Surface area of a cone = πr(r + l)

where

Therefore,

r = 4cm

l² = 4² + 3²

l² = 16 + 9

l = √25

l = 5 cm

Hence,

r = 4 cm

l =  5 cm

Surface area of a cone = π(r + l)

Surface area of a cone = 4π(4 + 5)

Surface area of a cone = 4π(9)

Surface area of a cone = 36π

Step-by-step explanation:

Answer:

y = 2 x 2 + 2 x + 4 should be the function.

Step-by-step explanation:

The last one can be anything, it said to predict so basically guess. From what I read from the graph, the y ( number of fruit flies ) doubles.

4 + 4 = 8

8 + 8 = 16

16 + 16 = 32

32 + 32 = 64

I'm sure your able to catch on.

Answer:

8/5

Step-by-step explanation:

Slope of the line = (-1-4)/(2-0)= -5/2

Equation of the line :

=> y - y1 = m(x - x1)

=> y - 0 = (-5/2)(x - 4)

=> 2(y - 0) = - 5x + 20

=> 2y + 5x = 20

To make the RHS 16, divide both sides by 20 and multiply by 16:

=> (2y/20)*16 + (5x/20)*16 = (20/20)*16

=> 8y/5 + 4x = 16

compare the equation with ax + by = 16 for y, b = 8/5

Answer:

c

Step-by-step explanation:

C becasue 1 week = 15 mulitipication facts memorized

There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.

Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.

13 miles = 68,640 feet

One car is of 15 ft

Let there be x cars,

15x = 68,640

x = 4576

Therefore,  there are 4576 cars in traffic.

If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.

Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Answer:

[tex]y = - \frac{1}{3} x - 4[/tex]

Step-by-step explanation:

The equation of a kind can be written in the slope intercept form, y= mx +c, where m is the gradient and c is the y-intercept.

[tex]\boxed{gradient = \frac{y1 - y2}{x1- x2} }[/tex]

[tex]m = \frac{ - 2 - ( - 3)}{ - 6 - ( - 3)} [/tex]

[tex]m = \frac{ - 2 + 3}{ - 6 + 3}[/tex]

[tex]m = \frac{ 1}{ - 3} [/tex]

Substitute the value of m into the equation:

[tex]y = - \frac{1}{3} x + c[/tex]

To find the value of c, substitute a pair of coordinates.

When x= -3, y= -3,

[tex] - 3 = - \frac{1}{3} ( - 3) + c[/tex]

[tex] - 3 = 1 + c[/tex]

c= -3 -1

c= -4

Answers:

The values are approximate. Round them however you need to.

====================================================

Explanation:

The diagram you have drawn is correct if you're only considering one current. Specifically current #1 which has the bearing of 290 degrees moving at 25 knots.

The red angle is 290 degrees. The remaining portion that is needed to get a full 360 degrees is 360-290 = 70. This adds to the blue portion in quadrant 1, which is 90, and we get 70+90 = 160. So the blue angle is 160 degrees.

The vector for current #1 is <25*cos(160), 25*sin(160)>

This approximates to <-23.4923155, 8.5505036>

All of this is for current #1.

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

Vector #2 is much more simple in terms that there aren't messy decimal approximations here. The direction is due north, which means that the vector is pointing straight up toward 90 degrees.

We can then say: <12*cos(90), 12*sin(90)> = <12*0, 12*1> = <0, 12>

Vector #2 is <0,12>

When you wrote <12,0>, you were on the right track, but you had the coordinates swapped in the wrong order.

----------

Then we have to account for a wind going 4 knots in the southwest direction. This is at the angle 225 degrees (we rotate 180 degrees plus another 45 to get 225). So,

vector #3 = <4*cos(225), 4*sin(225)> = <-2.8284271, -2.8284271>

This vector's coordinates are approximate

---------

To recap everything so far, vectors 1 through 3 are the following

I'm using variables to represent the vectors at this point, so we can then add them up to get...

s = p+q+r

s = <-23.4923155, 8.5505036> + <0,12> + <-2.8284271, -2.8284271>

s = <-23.4923155+0+(-2.8284271), 8.5505036+0+(-2.8284271)>

s = <-26.3207426, 5.7220765>

Vector s represents the sum of the three vectors p, q, and r. The two currents and the wind ultimately combine together to push the boat in the direction and along the length of vector s.

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

Now that we know the coordinates of vector s, we use them to find the true speed and true bearing of the boat.

speed = sqrt(a^2 + b^2)

speed = sqrt( (-26.3207426)^2 + (5.7220765)^2 )

speed = 26.935546 knots, which is approximate

angle = arctan(b/a)

angle = arctan(5.7220765/(-26.3207426))

angle = -12.265139

Add 360 to this angle to find that we get to the coterminal angle of -12.265139+360 = 347.734861 degrees

This angle is in quadrant 4, which is the southeast quadrant. If we rotate another 360-347.734861 = 12.265139 degrees, going counterclockwise, then we'll face directly east. Then another 90 degree counterclockwise rotation has us face directly north.

In total, the true bearing is approximately 90+12.265139 = 102.265139 degrees

So we'll start aiming north, and then rotate roughly 102.265139 degrees toward the east to get to the true bearing.

Answer:

Step-by-step explanation:

10! = 10 × 9 × 8!

so 10!/8! = 10×9 = 90

The factorial of an integer is the product of that integer and all the positive integers less than it. So, 3! = 3×2×1, for example. 0! is defined as 1.

Answer:

Angle L = 44

Angle M = 93

Angle O = 88

Angle P =  74

Step-by-step explanation:

First find your x, all angles will equal 360 when put together

360=61+x+(2x+5)+(x+30)+(2x)

360 = 61 + 5 +30 + x + 2x + x + 2x

360 - 96 = 6x

264 = 6x

264 / 6 = x

44 = x

Now place 44 in place of all x

Angle L:

x = 44

Angle M

(2x+5) = 2*44 + 5 = 93

Angle O

2x = 2*44 = 88

Angle P

(x+30) = 44 + 30 = 74

the answer would be 7/8
