Answer:

A. (-4, 6 )

Step-by-step explanation:

Signals of x and y in each quadrant:

Suppose we have a point P(x,y).

In the first quadrant, we have that both are positive, that is, x > 0, y > 0.

In the second quadrant, x is negative, while y is positive, that is, x < 0, y > 0.

In the third quadrant, both are negative, that is, x < 0, y < 0.

In the fourth quadrant, x is positive while y is negative, that is, x > 0, y < 0.

In this question:

In the second quadrant, we have x negative and y positive, so the ordered pair that best describes is given by option A.

Answer:

y=5

Step-by-step explanation:

25-20=y

Therefore: y=5

Answer:

y = 5

Step-by-step explanation:

25 = y + 20         Subtract 20 from both sides

-20        -20

5     = y

Answer: B. Completely Randomized Design

Step-by-step explanation:

A completely randomized design is an experimental design such that treatments are assigned at random completely in order for each experimental unit to have same chance of receiving treatment.

In this scenario, since all the dogs are randomly assigned treatment by picking a card without taking into consideration other factors, then we can infer that thus is a completely randomized design.

I think its D

Answer:

x = 19

Step-by-step explanation:

The two angles form a right angle

A right angle has a measure of 90 degrees

Thus, x + 14 + 3x = 90

               ^This is the equation we will use to solve for x

x + 14 + 3x = 90

step 1 combine like terms

x + 3x = 4x

we now have 4x + 14 = 90

step 2 subtract 14 from each side

90 - 14 = 76

14 - 14 cancels out

we now have 76 = 4x

step 3 divide each side by 4

4x / 4 = x

76 / 4 = 19

we're left with x = 19

Answer: 13 is a rational number

Step-by-step explanation: By definition, a rational number is a number q that can be written as a fraction in the form q=a/b where a and b are integers and b≠0. So, 1/3 is rational because it is exactly what you get when you divide one integer by another.

Answer:

392

Step-by-step explanation:

I would separate this into 2 shapes a triangle and a square. So first take the area of the square

area of square = base x height

16x19=304

Than take the area of the triangle

area of triangle = 1/2(base x height)

you can find the height of the triangle by subtracting 19 from 30 which is 11, and the base is the same as the base of the square which is 16

1/2(16x11)= 88

Add them together

304+88=392

Answer:

-9x^2+x-10

Step-by-step explanation:

Answer:

Answer is Option B.

That is the nth term of the sequence.

1/8 + 1/16 + 1/32....

You notice that all the numerators are the same. Which is (1).

so we have to both about getting the nth term of the denominator

Since all the denominator are divisible by 2... and Your intuition should tell you that they'd multiples of 2

So Lets go with 2^n

2^n

let n be all Integers

let take 1,2,3

2¹ = 2

2² = 4

2³ = 8

Now Observe that

If you multiply all these by 4... We will have all the values of the denominator

which are 4,16,32

So thats our nth term

1/4(2^n)

as n approaches positive Infinity.

The expression is [tex]\lim_{n \to \infty} \frac{1}{4(2^{n}) }[/tex] , so option (B) is the correct expression.

"A series expansion is an expansion of a function into a series or infinite sum. It is a method for calculating a function that cannot be expressed by just elementary operators (addition, subtraction, multiplication, and division)".

For the given situation,

The series is given as [tex]\frac{1}{8} +\frac{1}{16}+ \frac{1}{32}+ \frac{1}{64}+ \frac{1}{128}+......[/tex]

In the series, all the numerators are 1 and the denominators are even numbers so multiples of 2.

Now, we examine the denominators alone.

[tex]8,16,32,64,128[/tex]

⇒ Multiples of 2. So we get [tex]2^{n}[/tex] multiplied by some integers.

Put [tex]n=1,[/tex]

⇒ [tex]2^{1}[/tex] × [tex]4=8[/tex]

Put [tex]n=2,[/tex]

⇒ [tex]2^{2}[/tex] × [tex]4=8[/tex]

Put [tex]n=3,[/tex]

⇒ [tex]2^{3}[/tex] × [tex]4=32[/tex]

Put [tex]n=4,\\[/tex]

⇒ [tex]2^{4}[/tex] × [tex]4=64[/tex]

Put [tex]n=5[/tex],

⇒ [tex]2^{5}[/tex] × [tex]4=128[/tex]

Thus [tex]2^{n}[/tex] expression becomes [tex]2^{n}(4)[/tex] .

Hence we can conclude that the expression is [tex]\lim_{n \to \infty} \frac{1}{4(2^{n}) }[/tex] . So option (B) is the correct expression.

Answer:

B. 75

Step-by-step explanation:

According to vertical angles theorem, angles that are opposite of one another with shared lines will be equal, so we can set 5x = x +60.

Solving for x, we get x = 15, and substituting into the angle we get 15 + 60 = 75 degrees.

Answer:

12

Step-by-step explanation:

Use the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c

[tex]a^2+b^2=c^2[/tex]

[tex]5^2+b^2=13^2[/tex]

[tex]25+b^2=169[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

Answer:

b = 12m

Step-by-step explanation:

5^2 + b^2 = 13^2

25 + b^2 = 169 --> *subtract 25 form both sides*

b^2 = 144 --> find square root of 144*

b = 12

Answer:

13.74

Step-by-step explanation:

Answer:

13.74

Step-by-step explanation:

Add 0.4+0.3 = 0.7, so the equation now looks like this: 12.95+0.7+0.09

Add 0.7 + 0.09 = 0.79, so the equation now looks like this: 12.95 + 0.79

Add 12.95 + 0.79, so now you are left with: 13.74

Answer: the answer is  |x-5,if x<5|

Step-by-step explanation:

Answer:

the Pythagorean theorem states:  

a^2 + b^2 = c^2  in your case a=24 and c=40

Step-by-step explanation:

24^2 + b^2 = 40^2

24x24 + b^2 = 40x40

(576 + b^2 = 1600)  

b^2 = 1600 - 576

b^2 = 1024

b= √1024

b = 32

Final answer: 32

The length of b is 32 units in triangle ΔABC.

Pythagoras theorem states that, a right-angled triangle, the square of the one side is equal to the sum of the squares of the other two sides.

a² + b² = c²

Given data as :  a=24 and c=40

Substitute the values of a and c in the equation,

24² + b² = 40²

24x24 + b² = 40x40

(576 + b² = 1600)  

b² = 1600 - 576

b² = 1024

b= √1024

b = 32

Hence, the length of b is 32 units.
