Answer:

Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Step-by-step explanation:

Here, we want to choose the correct option

As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola

So the correct answer in this case is that;

Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Answer:

UW = EW+UE=2×EW because, EW=UE

7x-2=2×6= 12

7x=14

x=14/7

x=2

x + 80 = 180 - (64 + 36)

x + 80 = 180 - 100

x + 80 = 80

x = 0

Answer:

e. -490

Step-by-step explanation:

-318+3= -315

-315/9= -35

So that would mean m= -35

-35*14= -490

Answer:

3 , 11, 25, 45

Diff 8 14 20

Diff 6 6

The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3

therefore 3n^2

3 11 25 45

3n^2 3 12 27 48

Remainder 0 -1 -2 -3

Difference -1 -1 -1

linear sequence with nth term -n+1

so nth term of quadratic sequence in 3n^2-n+1

Answer:

5/9

Step-by-step explanation: If you find a common denominator ( i found 135 ) and you multiply each numerator by the number u multiplied the denominator to get the common denominator, you can see that 5/9 is greater. hope this helps and sorry if that was confusing

Answer:

5/9 is greater

Step-by-step explanation:

As numerator of second ratio is greater, Hence, 5/9 is greater.

Answer:

the answer is 4.5 but you cannot plant 4 and a half seeds. so the answer would be 3.

Step-by-step explanation:

Answer:

3x + 9

Step-by-step explanation:

You basically want the total amount of seeds so if he plants x in one garden and 2x + 9 in another, you add them both

x + 2x + 9

Equals 3x + 9

Answer:

Step-by-step explanation:

According to sine law of trigonometric functions,

sin(α)/a =sin(β)/b

hence using this

sin(18)/y = sin(x)/2y

sin(x)=2*sin(18)

sin(x)=2*0.309

sin(x)= 0.618

x=sin-1(0.618)     ( sin-1  is sine inverse)

x=38.17 °

Answer:

y + 1 = 4/3(x - 9)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

Substitute the numbers into the equation:

y - (-1) = 4/3(x - 9)

y + 1 = 4/3(x - 9)

Step-by-step explanation:

a^2 +b^2 = c^2. Since 18 would be c in this equation, you just do 18 squared minus 8 squared.

Answer:

17.89 m

Step-by-step explanation:

A^2+B^2=C^2

8squared=64

18squared=256

64+256=320

320 (radical)

17.89 m

320 girls & 250 boys

0.2 probability     0.1 probability

320 x 0.2 = 64

250 x 0.1 = 25

64 + 25 = 89

There are approximately 89 students in the school that are left-handed.

Answer

89% of the people are left handed

Step-by-Step Explanation

To find this you have to first do 320 x 0.2

320 x 0.2= 64

To find it for boys you have to do 250 x 0.1.

250 x 0.1= 25

SO, the answer is 89%. 64% of girls and 25% of boys

Answer:

the difference is 25.5

Step-by-step explanation:

34.1 - 8.6 = 25.5

[tex]42.7^{\circ}F[/tex]

Subtract the number with the smallest value from the number with the biggest value to determine the difference between two numbers.

Temperature in a town during the day [tex]=34.1^{\circ}F[/tex]

Temperature in a town during the night [tex]=-8.6^{\circ}F[/tex]

Therefore,

Difference in temperatures [tex]=34.1-(-8.6)[/tex]

                                            [tex]=42.7^{\circ}F[/tex]
