What is the vertex of the quadratic function below? y=1/2x^2+x+3

Answer:

124.3 ft

Step-by-step explanation:

We solve the above question using the Trigonometric function of Tangent

= tan θ = Opposite/Adjacent

θ = Angle of Elevation = 73°

Adjacent = 38 ft

Opposite = x

Hence

tan 73° = x/38 ft

Cross Multiply

x = tan 73° × 38 ft

x = 124.2923995 ft

Approximately = 124.3 ft

Therefore, Nick is 124.3 ft from the ground.

Answer:

B. The second graph ! :)

Answer:

okay the first best step is to subtract 100 from both side the second best step is to divide 15 by both side

C

C is the answer. It is the only one that gives y when you input x.

Answer:

Your answer is C :)

Y = 3^x + 2.

You just substitute this into any of the functions. If you need more clarification I can help :)

Answer:

Median --> 357.5

Q1 --> 298

Q3 --> 422

IQR > 124

Step-by-step explanation:

3 daily attendance at the water park: 346, 250, 433, 369, 422,298

Find the median, Q1, Q3,and IQR

Step 1

We rearrange the given data set

250, 298, 346, 369, 422, 433

a) The Median

The formula to find the Median

= 1/2( n + 1)th term

Where n = Number of terms = 6

Median = 1/2(6 + 1)th

= 1/2(7)th term

= 3.5th term

The 3.5th term = The number between the 3rd and 4th term

3rd term = 346

4th term = 369

Hence,Median = 346 + 369/2

= 357.5

2) Q1 = First Quartile

= 1/4(n + 1)the

= 1/4( n + 1)th term

Where n = Number of terms = 6

Median = 1/4(6 + 1)th

= 1/4(7)th term

= 1.75th term

The 1.75th term = 2nd term

= 298

Q1 = 298

3) 3/4( n + 1)th term

Where n = Number of terms = 6

Median = 3/4(6 + 1)th

= 3/4(7)th term = 21/4th term

= 5.25th term

The 5.25th term = 6th term

Q3 = 422

4) Interquartile Range = Q3 - Q1

= 422 - 398

= 124

Answer:

15.833 pints of chalkboard paint

Step-by-step explanation:

Surface area of a rectangular prism = 2(lw × hl × hw)

Where,

L = length = 15 feet

w = Width = 13 feet

h = height = 10 feet

Surface area of a rectangular prism = 2(lw + hl + hw)

= 2(15*13 + 10*15 + 10*13)

= 2(195 + 150 + 130)

= 2(475)

= 950 square feet

One pint of chalkboard paint covers 60 square feet

Least number of pints needed to paint the walls = 950 square feet / 60 square feet

= 15.833 pints of chalkboard paint

The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;

2x^2−x+55 = (x+5)^2

2x^2−x+55 = x^2 + 10x + 25

Collect the like terms;

2x^2-x^2-x-10x+55-25 = 0

x^2 - 11x + 30 = 0

Factorize the result

x^2 - 6x - 5x + 30 =0

x(x-6)-5(x-6) = 0

x-5 = 0 and x - 6  = 0

x = 5 and 6

Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Answer:

-6

Step-by-step explanation:

Ok so if x=2

you have to do -3*2

and thats -6

hope this helped

good luck

Please read through this carefully. I’d love to help, but I want you to understand why this is the answer and not just copy and paste.

Answer:

1. -6

2. 20

Step-by-step explanation:

1. Simply replace x with 2, since x=2. 2x -3 is the same as -3+-3, which is -6.

2. Simply replace x with 2, since x=2. 2x5 is the same as 5+5, which is 10. 10+10=20, therefore, the answer is 20.

Distance is 124

Step-by-step explanation:

73 + 51

124

Answer: 124

Step-by-step explanation:

| 73 - (-53) |

124

Step-by-step explanation:

sin^2(x)= 3 cos^2(x)

Subtract sin^2(x) on both sides

0=3cos^2(x)-sin^2(x)

By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)

0=3(1-sin^2(x))-sin^2(x)

Distribute

0=3-3sin^2(x)-sin^2(x)

Combine like terms

0=3-4sin^2(x)

Add 4sin^2(x) on both sides

4sin^2(x)=3

Divide both sides by 4

sin^2(x)=3/4

Take the square root of both sides

sin(x)=+ or - sqrt(3/4)

sin(x)=+ or - sqrt(3)/sqrt(4)

sin(x)=+ or - sqrt(3)/2

This happens on the unit circle at

60 degrees

120 degrees

240 degrees

300 degrees

If we go around and around again forwards or backwards, we get the infinitely many other solutions including the one's already stated in the following solution sets

(60 +360n) degrees

(120 +360n)degrees

(240 +360n)degrees

(300 +360n)degrees

where n is an integer

x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.

240 degree one or the (240+360n) degrees terminates in the third.

Answer:

the right answer is:

Step-by-step explanation:

You take the equations that the exercise give you:

Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:

   3. y =  x - a

And now, you'll replace this third equation in the equation you didn't take (the first in this case).

Add the x variables:

That's the answer of the exercise, but you can represent this in this form:

By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].

Answer:

17,430g

Step-by-step explanation:

convert kilogram to gram

1kg = 100g

0.83 x 1000 = 830g

there are 7 days in a week

7 x 3 = 21 days

total grams used in 3 weeks = 21 x 830 = 17,430g

Answer:

The probability is 1/32

Step-by-step explanation:

What the question asks here is that in a throw of a coin 5 times, what is the probability that we have the head being revealed once in the 5 throws

for a fair coin, we can only get a head or a tail

So the probability of getting a head equals that of getting a tail

Since total probability is 1; then the probability of each will be 1/2

So, we can now have the probability as follows;

1 head (1/2) and 4 tails (1/2 * 1/2 * 1/2 * 1/2)

1/2 * 1/2 * 1/2 * 1/2 * 1/2 = (1/2)^5 = 1/32
