The Height Of An Acorn Falling Out Of A Tree Is Given By N = -16t2 + B. If An Acorn Takes 1 Second To
Answer 2

Answer:

b = 16.

Step-by-step explanation:

When the acorn reaches the ground the height n = 0. So we have:

-16(1)^2 + b = 0

-16 + b = 0

b = 16.

There are 10 chocolates in a box.
7 of the chocolates have soft centres and 3 of the chocolates have hard centres. Kyla takes at random a chocolate from the box and eats it.
She then takes at random another chocolate from the box and eats it.

Answers

What’s the question?

The probability of getting chocolates with harder center is 7/15.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, there are 10 chocolates in a box. 7 of the chocolates have soft centers and 3 of the chocolates have hard centers.

Probability of choosing first chocolate with hard center is

Total number of outcomes =10

Number of favorable outcomes =7

Now, probability is 7/10

Probability of choosing second chocolate with hard center is

Total number of outcomes =9

Number of favorable outcomes =6

Now, probability is 6/9

Probability of an event = 7/10 × 6/9

= 7/10 × 2/3

= 7/5 × 1/3

= 7/15

Therefore, the probability of getting chocolates with harder center is 7/15.

The equation of the piecewise function f(x) is below. What is the value of f(3)?

Answers

Answer:

5

Step-by-step explanation:

Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...

F(3)=x+2

F(3)=3+2

F(3)=5

We are to check the options and choose which applies to the triangle

The options which applies is option C, Scalene and option For, Acute

Obtuse: It is not an obtuse angle because none of the angles are greater than 90°

Isosceles: It is not an isosceles triangle because it has no two equal sides

Scalene: It is a scalene triangle because all the sides are not equal sides

Equilateral: It is not an equilateral triangle because all the sides are not equal

Right: It is not a right angle because none of the angles form a straight line equivalent to 90°

Acute: It is an acute angle because the angles measures less than 90°

The correct answer is Scalene and acute
