Find f(x)=(x^2)+x+39, when x=50. (don't write a comma in answer.)

Answers

f(x) = x² + x + 39

f(50) = 50² + 50 + 39

f(50) = 2500 + 89

Anna said that the product of 78⋅112=7278·112=72.


How can you tell that her answer is wrong?

Answers

Answer:

The easiest way I can think of to show someone who is not very mathematically inclined that the calculation is wrong (other than using a scientific calculator) is this:

Explain that one half contains four eighths - you can visualize this very simply with a pie chart.

Then tell Anna that mathematically speaking this translates to the equation:

1/2 = 4 * 1/8

Now, if ONE half is equal to four times ONE eighths, then SEVEN halves is equal to four times SEVEN eighths - basically, you just multiply both sides by 7:

7/2 = 4 * 7/8

Now, compare this to the equation proposed by Anna:

7/2 = 1½ * 7/8

I guess, at this point it will be easy to convince Anna that 1½ is not 4, and therefore her equation is faulty.

-----

Alternatively, if she's sound with fractions you could also tell her that to get from 7/8 to 7/2 you will need a factor which only affects the denominator as the numerator stay the same. The factor that turns 8 into 2 is 1/4 but since this takes place in the denominator we need the reciprocal to turn 1/8 into 1/2 - and the reciprocal of 1/4 is of course 4. At which point we've arrived at the same place of argumentation as before (which is that 4 ≠ 1½).

#5 angle 1 = 97 degrees

#5 angle 2 = 82 degrees

#5 angle 3 = 83 degrees

Step-by-step explanation:

The image displays which angles are the same on line equations like these using color coding.

In order to translate between the green angle and the pink angle you subtract it from 180.

Equation: 180 - angle type 1 = angle type 2

Tennis balls: Must rebound approximately 111 cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120 cm when dropped from 200 cm onto a steel plate. Basketballs: Must rebound approximately 53 .5 inches when dropped from 72 inches onto a wooden floor. Squash balls: Must rebound approximately 29 .5 inches when dropped from 100 inches onto a steel plate at 70∘ Which ball listed above is the bounciest

Answers

Answer:

There is no basis for comparison because the effect of the other variables that are not being studied are not minimized

Step-by-step explanation:

The rate at which each type of ball bounce are;

Tennis balls;

The height to which the ball is must rebounds ≈ 111 cm

The height from which the ball is dropped = 200 cm

Surface = Steel plate

Basketballs;

The height to which the ball must rebounds ≈ 5.35 inches

The height from which the ball is dropped = 72 inches

Surface = Wooden floor

Squash balls

The height to which the ball must rebounds ≈ 29.5 inches

The height from which the ball is dropped = 100 inches

Steel plate at 70°

Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison

Answer:

a) 16.4 kmb) 79°c) 10 km

Step-by-step explanation:

Find the m∠B:

m∠B = (360° - 310°) + 50° = 100°

a)

Find AC using law of cosines:

AC = √(8² + 13² - 28*13*cos 100°) = 16.4 km (rounded)

b)

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?

a) 3 1/8
b) 1/8
c) 8
d) 8/25

Answers

Answer:

b) 1/8

Step-by-step explanation:

5/8 ÷ 5 = 1/8

The unit rate in cups per teaspoon is 1/8 cup of sugar.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

5/8 cup of sugar=5 teaspoons of vanilla.

or, 5 teaspoons of vanilla = 5/8 cup of sugar

So, 1  teaspoon of vanilla = (5/8)/5 cup of sugar

(5/8)/5 = (5/8)*(1/5)

(5/8)/5 =1/8

So, 1 teaspoon of vanilla = 1/8 cup of sugar

Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.
