The truth table is completed for each column as T T F F T T T

A truth table is a mathematical table which shows all the truth values of a given combination of logic statements.

Analysis:

The truth table is shown in the attached file

in the attached file, the first two columns were given,

The third column is the negation of p, and P is true(T) which means its negation is false(F).

The fourth column is the negation of Q, which means Q is true(T) so its negation is false(F).

In the fifth column, negation P is implies negation Q. The truth table for implication, is only false if Q is false, else it is True.

Same as in the sixth column.

The last column is bi-implication, the truth table for this only true, if both statements are false or both are true else, it is false.

In the case above, Jaime claim is true.

1. Note that radian measure:

=   [tex]\frac{60° }{360°}[/tex] x 2π  x 3

= 1/6 x 6π  

= π  

2. Note that radian measure:

=  [tex]\frac{60° }{360°}[/tex] x 2π  x 6

= 1/6  x 2π  x 6

=2π  

So we can write it as:

π/3  x 180°/π    = 60°

Therefore, via the solution above, Jaime claim is true.

3. Note that: Radian measures: the percentage of arc measures x  2π  x radius and so one can say that The explanation to agree with Jaime’s statement or not is that the longer the length of the radius, the longer the length of the arc.

Answer:

27

Step-by-step explanation:

When solving complicated equations like this, we need to remember the order of operations (PEMDAS), which is the order that we solve an equation

P arentheses

E xponents

M ultiplication

D ivision

A ddition

S ubtraction

now, here's the thing: we actually to multiplication/division at the same time, and the same thing with addition/subtraction

(as in, adding -4 is the same thing as subtracting 4, so we can't truly make a distinction between the two)

so, when we have multiple instances of multiplication/division , we solve left to right

(and then the same thing for addition/subtraction)

8 × 3 + 70 ÷ 7 - 7

so, we first need to multiply 8 by 3

8 × 3 = 24

next, we move to the right:

and we divide 70 by 7

70 ÷ 7 = 10

let's rewrite our equation:

(24) + (10) - 7

24 + 10 - 7 = 27

so, the answer to this expression is 27

The expression that is equivalent to 2.3p – 10.1 = 6.5p – 4 – 0.01p are given below,

If the given expression 2.3p – 10.1 = 6.5p – 4 – 0.01 is simplified, then the expression can be written as,

2.3p – 10.1 = 6.5p – 4 – 0.01

2.3p – 10.1 = 6.49p – 4

Thus, Option A is one of the option.

Using the multiplication property of Equality, if we multiply both the sides of the equation by 100, then we will get,

230p – 1010 = 650p – 400 – p

A quadratic equation is in the form of ax²+bx+c. The time at which the height of the ball is 16 feets is 0.717 seconds and 1.221 seconds.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

The complete question is:

A ball is thrown from an initial height of 2 feet with an initial upward velocity of 31 ft/s. The ball's height h (in feet) after 7 seconds is given by the following, h=2+31t-16t². Find all values of t for which the ball's height is  16 feet. Round your answer(s) to the nearest hundredth.

The time at which the height of the ball is 16 feet can be found by,

h = 2 + 31t - 16t²

16 = 2 + 31t - 16t²

16 - 2 - 31t + 16t² = 0

16t² - 31t + 14 = 0

[tex]t = \dfrac{-(-31)\pm \sqrt{(-31)^2-4(16)(14)}}{2(16)}\\\\[/tex]

t = 0.717 , 1.221

Hence, the time at which the height of the ball is 16 feets is 0.717 seconds and 1.221 seconds.

Answer: y = -x + 5

Step-by-step explanation:

      A slope-intercept equation is in the form y = mx + b where m is the slope and b is the y-intercept. Since we are given the slope, we will plug it in with the point they gave us, and solve for b.

y = mx + b

(1) = (-1)(4) + b

1 = -4 + b

5 = b

      Lastly, we will write our equation by substituting m with -1 and b with 5.

y = mx + b

y = -1x + 5 or y = -x + 5

Answer:

33.75 Euros

Step-by-step explanation:

Trust me bro, I did the working.

Explanation:

When you change the size of a shape by a scale factor ("enlarge" means increasing the shape by a scale factor > 1), you increase all dimensions of that shape by a factor.

For example, if a rectangle's length is 2 units [two boxes in this case]. you make that size 6 units [2 · 3 = 6]; and if its width is 1 unit, you make that 3 units [1 · 3 = 3]

[scaling up our dimensions:]

So, we apply the same logic here. Any side length is now three times longer, so when the original length [along the bottom] was two boxes, that should now cover 6 boxes.

The height of 1 box [left side] will now be expanded to 3 boxes.

The other height of 2 boxes will now be 6 boxes [2 · 3 = 6]

The slanted portion should be easy to connect between your new side lengths and width

[but you could always use Pythagorean theorem to figure out the length; it would be 1² + 2² = c², or 5 = c², so the literal length of this side would be √5 ; you probably aren't expected to do this / you don't have to]

You didn't show the new graph to graph it on, but this is how you would graph it.

hope this helps!! have a lovely day :)
