<h3>Answer:</h3>

Option B: 63

<h2>Given that:</h2>

The given function is    f(x)=2x^2+2x+3

<h2>Explanation:</h2>

To evaluate the value of a function at given value of input, you should replace the variable given in the function with the value of input that is given, in your case it is x = 5.

For x = 5, we have

f(5) = 50 + 10 + 3      = 63

Similarly, you will be able to evaluate the value of the function for any other input given, which is assumed to be valid.

Hence option b: 63 is the correct option.

ExtremeBDS [4]

Answer:

Looking for four values or answers

(A) 5.05

(B) 13

(C) $254,140.33

(D) $254,145.38

Step-by-step explanation:

(A) The value of the margin of error.

Using a 90% confidence level or 0.10 alpha level,

1 - alpha = 1 - 0.10 = 0.90

The degrees of freedom = n - 1 = 14 - 1 = 13

Using the t table, 0.90 under 13 is 1.350

Sample size divided by √n is equal to

14/√14 = 3.742

1.35 × 3.742 = 5.05

(B) 13 degrees of freedom

(C) To find the lower and upper limits, you find the mean value first and then subtract / add to half of the margin of error which is 5.05÷2 = 2.525

Adding the 14 values together, you have $3,558,000

Dividing by 14 to get the mean;

Mean = $254,142.8571

Lower Limit: $254,140.33

Upper Limit: $254,145.38

Sandra bought a tube of toothpaste for $1.89, shampoo for $3.19 and a jar of peanuts for $2.29 from the local supermarket. Using
uranmaximum [27]
To find the total cost, you need to add these numbers together

1.89 + 3.19 + 2.29 = 7.37
you get 7.37 as your answer, but you need to round this to the nearest whole number.

rounding 7.37 will make it 7.

the total cost is about $7

If RSTU is a rhombus, find the measure of angle RUT.
Schach [20]

<u>Finding x:</u>

We know that the diagonals of a rhombus bisect its angles

So, since US is a diagonal of the given rhombus:

∠RUS = ∠TUS

10x - 23 = 3x + 19                      [replacing the given values of the angles]

7x - 23 = 19                                [subtracting 3x from both sides]

7x = 42                                       [adding 23 on both sides]

x = 6                                           [dividing both sides by 7]

<u>Finding ∠RUT:</u>

We can see that:

∠RUT = ∠RUS + ∠TUS

<em>Since we are given the values of ∠RUS and ∠TUS:</em>

∠RUT = (10x - 23) + (3x + 19)

∠RUT = 13x - 4

<em>We know that x = 6:</em>

∠RUT = 13(6)-  4

∠RUT = 74°

A ball is thrown at an initial height of 7 feet with an initial upward velocity at 27 ft/s. The balls height h (in feet) after t
lianna [129]

Answer:

The height of ball is 17 ft at t=0.55 and t=1.14.

Step-by-step explanation:

The general projectile motion is defined as

y=-16t^2+vt+y_0

Where, v is initial velocity and y₀ is initial height.

It is given that the initial height is 7 and the initial upward velocity is 27.

Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.

h(t)=-16t^2+27t+7

The height of ball is 17 ft. Put h(t)=17.

17=-16t^2+27t+7

0=-16t^2+27t-10

On solving this equation using graphing calculator we get

t=0.549,1.139

t\approx 0.55,1.14

Therefore the height of ball is 17 ft at t=0.55 and t=1.14.
