which angles are coterminal with 3pi/2 ​

Answer: 6

Step-by-step explanation:

F(-3), you will find out by replacing the x with -3

f(-3)=(-3)^2+(-3)=9-3=6

Answer:

B - 1/9

Step-by-step explanation:

I don't really know how to explain how I got it because I'm only in middle school in pre-algebra, but I did teach this to myself online haha, so here we go. Daneille rolled the dice 90 times, it only landed on 6 10 times. That is 10/90 which, simplified, is 1/9.

Answer:   =25.35

im sure its right

Answer:

123

Step-by-step explanation:

(6^2+5)*3= 41*3= 123

Answer:

Step-by-step explanation:

take away the parenthesis

9 - 3 = 6

6² + 5 ÷ ⅓

take away the exponents

6 * 6 = 36

36 + 5 ÷ ⅓

36 + 5 = 41

41 ÷ ⅓

( 41 ÷ 1 ) ÷ 3

41 ÷ 3

13.66666666666667

Round it up, and u get

13.7 or 14 depends on how much u want to round it up to.

Hope this helped!

Answer:  It takes 3 seconds to do one of both i think

Step-by-step explanation:

19 and 6 was 75 and 18 and 6 was 72 which means 1 push up is 3 seconds multiply 3 by 18 that is 54 then subtract 72 by 54 which gives you 18 then divide 18 by 6 which is 3

Step-by-step explanation:

Answer:

The length of the box is (x + 1)

The height of the box is (x + 1)

Step-by-step explanation:

The given function representing the volume of the box is presented as follows;

V = x³ + 6·x² + 9·x + 4

The function representing the width of the box, W = x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1

x³ + 4·x²

    [tex]{}[/tex]  2·x² + 9·x + 4

    [tex]{}[/tex]  2·x² + 8·x

    [tex]{}[/tex]               x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)

The width of the box = (x + 4)

The length of the box = (x + 1)

The height of the box = (x + 1).

Answer:

The height of the triangle is: h = 6.4 cm

Step-by-step explanation:

Given

Area of the triangle A = 40 cm²

The Base of the triangle b = 12.5 cm

To determine

height of triangle h = ?

We know that the area A of a triangle is:

A = 1/2 bh

where

so

A = 1/2 bh

substituting A = 40 and b = 12.5

40 = 1/2 (12.5) h

40 × 2 = 12.5 h

12.5 h = 80

divide both sides by 12.5

12.5h/12.5 = 80/12.5

h = 6.4 cm

Thus, the height of the triangle is: h = 6.4 cm

Answer: 8 Hours to finish her homework.

Step-by-step explanation: We know each page, or 1 page takes 1 hour to finish. We want to know how many hours it would take to take finish 8 pages of homework. To find this, simply multiply 1 by 8. (1 hour per page, or 1 hour for each of the 8 pages.)

1 x 8 = 8.

So it will take Meredith 8 hours to finish her homework.

Answer:

it will take 8 hours if you mean one page an hour

Answer:

X is parent 1

z is parent 2

y is parent 3

Answer:

12.68

Step-by-step explanation:

With reference angle 45°

perpendicular (p) = 9

hypotenuse (h) = c

Now

sin 45 ° = p/ h

0.71 = 9 / c

c = 9 / 0.71

c = 12.68

Hope it will help :)

Answer:

No, X=7

Step-by-step explanation:

Answer:

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:

x-4y=6

x+4y=12

we see here that elimination would best fit:

x+x+4y-4y=6+12

or:

x=2y-3

7x+3y-81=23

substitute (2y-3) for x.

Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)

and use the quadratic formula:

x=(-b±sqrt(b^2-4ac))/2a

Answer:

1 1/9

Step-by-step explanation:

5/6 ÷ 3/4 = ?

5/6 x 4/3

5 x 4

-------   =   20/18 = 1 2/18 = 1 1/9

6 x 3

id-k but here we go

have you seen things of circles and triangles and squares? This problem is just like this. You would probably identify the squares circles and triagnles as...well....traingles circles and squares. Well, we do that but with the variables.

The numbers with 'x' is one group. And the one without it is another group. So....take 'x3' and take the x9. Because they have the same variable.

x3 +  x9. (why we are adding is because it has nothing to drag with it and both of these numbers are positive)

x12!

Now do teh same with 15 and 3. Bring the plus and the subtraction sign with 3 and 15. We cant just leave them there. 15-3=12.

we have 12. this must equal 12!!!!!

Answer: -1>4

Step-by-step explanation:

m = 4/5 for the perpendicular line

m = -5/4 for the parallel line

y = -5/4x + 3

for the line above, m = -5/4

The line parallel to this line would have exactly the same slope m =  -5/4

The line perpendicular to this line would have a  slope equal the inverse with the opposite sign  

m = -5/4

So m = (1/(5/4)) is the slope of the m for the perpendicular line

m = 4/5

Answer:

120 miles per hour

total time 3 hours

120 x 3= 360

the plane travels 360 miles

Step-by-step explanation:

Answer:

Someone calculated his or her average speed to 7.46 Miles per hour (mph) This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.

Step-by-step explanation:

The re sults your produce from the speed calculator input will come out in a variety of forms You can also find a report on your speed in terms of kilometres per hour, meters per minute and metres per second. There is also a report on the time it takes you to travel certain distances. This report shows you min:sec per kilometre, seconds per 100 .

Step-by-step explanation:

as we know

law of cosine

[tex]c = \sqrt{ {a}^{2} + {b}^{2} - 2ab. \cos(c) } [/tex]

[tex]c = \sqrt{ {14}^{2} + {18}^{2} - 2.14.18 - \cos( {35}^{o} ) } [/tex]

[tex]c = 10.35[/tex]

using the law of cosine

[tex]cos(a) = \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} [/tex]

[tex] \cos(a) = \frac{ {18}^{2} + {10.35 }^{2} - {14}^{2} }{2.18.(10.35)} [/tex]

[tex]a = {50.87}^{o} [/tex]

b=87.13°

Answer:

Please check the explanation.

Step-by-step explanation:

Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.

In other words,

P(x, y) → P'(-y, x)

From the given triangle ΔRST,

The coordinates of the point S is:

According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:

S(10, 1) → S'(-1, 10)

Here,

S'(-1, 10)  is the image of the original point or pre-image point S(10, 1).

Therefore, the y-coordinate of the point S' is: 10

Answer:

  1) see below

  2) 2.5 inches per day

  3) the seed was planted below ground level

  4) h = 2.5d -3

Step-by-step explanation:

1) We note that the seedling grew 12-7 = 5 inches in the 2 days between day 4 and day 6. This lets us fill in the numbers for even days by adding or subtracting 5 inches:

  day 8 will be 5 inches more than day 6, 17 inches.

  day 2 will be 5 inches less than day 4, 2 inches.

  day 0 will be 5 inches less than that, -3 inches.

The value for day 3 will be halfway between day 2 and day 4, so will be (2+7)/2 = 4.5 inches.

See the attachment for the complete table.

__

2) In one day, the plant grows in/day = 5/2 = 2.5 inches.

__

3) If the plant grows at the steady rate of 5 inches in 2 days, it must have been planted 3 inches below ground on day 0.

__

4) In question 2, we found the rate per day (slope) to be 2.5. In question 3, we found the "y-intercept" to be -3. Then the slope-intercept equation with independent variable d and dependent variable h is ...

  h = 2.5d -3
