Answer:

[tex]\frac{-3}{-26}[/tex]

Step-by-step explanation:

[tex]\frac{-x-8}{x^{2}-4x-21}[/tex] is what you are looking for.

So with x = -5, it would look like this

[tex]\frac{-(-5)-8}{-5^{2}-(-5)4-21}[/tex]

Simple math now.

-(-5) is 5

[tex]-5^{2} = -25[/tex]

-5 * -4 = 20.

So it should be [tex]\frac{5-8}{-25+20-21}[/tex]

5-8=-3

-25+20-21 = -26

So the answer is[tex]\frac{-3}{-26}[/tex]

Answer:

the circumference is 69.08

Step-by-step explanation:

If 22 is the diameter, all u do to find the circumference is multiply the diameter by 3.14.

Answer:

34.54

Step-by-step explanation:

22 is diameter

formula for circumference is radius  times pi

2 radius=1 diameter

22/2=11

11*3.14=34.54

Step-by-step explanation:

z = 180° - 113° = 67°

sum of angles of quadrilateral shape = 360°

y = 360° - ( 67° + 81° + 106° ) = 106°

Answer:

25/6

Step-by-step explanation:

Take the number on the left multiply by the denominator and add the numerator which is 4×6+1 =25

Reuse the same denominator which is 6 so 25/6

Work backwards: 25/6 to 4 1/6 (25 divide by 6 is 4 remainder 1 so 4 on the left and 1 as the numerator)

Answer:

25/6

Step-by-step explanation:

put the denominator as it is

434

because 7 times 31 will give u 217 and 217 divided by 4 will give an answer of 434.I hope my answer will help u.

Answer:

[tex](x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]

Step-by-step explanation:

Equation of circle is:

[tex](x - h) {}^{2} + (y - k) {}^{2} = r {}^{2} \\ [/tex]

Here (h,k) are the coordinates of center and r is radius

(h,k) =(2,-5)

r. = 4

plug in the values of h,k and r

[tex](x - 2) {}^{2} + (y - ( - 5)) {}^{2} = 4 {}^{2} \\ (x - 2) {}^{2} + (y + 5) {}^{2} = 16[/tex]

Answer:

[tex](x-2)^2+(y+5)^2=16[/tex]

Step-by-step explanation:

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where (a, b) is the center and r is the radius)

Given:

Substitute the given values into the equation:

[tex]\implies (x-2)^2+(y-(-5))^2=4^2[/tex]

[tex]\implies (x-2)^2+(y+5)^2=16[/tex]

Answer:

10 mm

Step-by-step explanation:

We know that the formula for a triangle is A= 1/2(b)(h)

Plug in 30mm for the area as shown and 6 for the base= 30=1/2(6)(h)

Solve= 30=3h

Divide each side by 3 to get h by itself. h=10 or b= 10

depends on which one is missing ^^

Step-by-step explanation:

Hello!

This is one of three special binomial products:

All you have to do is expand the parenthesis, and this will give you a simple format to follow. This can be used to quickly factor the expanded forms, or quickly multiply the factored forms.

An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of x in the given equation can be written as,

[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]

Hence, the value of x is the equation ax-b=c is (c+b)/(a).

The prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

[tex]E(X) = np\\[/tex]

Given that the characters that can be used are numbers 0 through 9 and lowercase letters. Therefore, a total of 36 different characters are available.

Since we need to know the passwords made with vowels, therefore, the probability of a password in which the first character will be a, e, i, o, u is (5/36).

Now as the computer produces 400 passwords, therefore, the predicted value can be written as,

[tex]E = np = 400 \times \dfrac{5}{36} = 55.5556 \approx 56[/tex]

Hence, the prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Answer:

The answer is AC = 3.76

Step-by-step explanation:

CohCahToa

Coh: sin(theta) = Opp/Hyp

sin(theta°) = AC/AB

sin(70°) = AC/4

AC = 4*sin(70°)

AC ≈ 3.758770483

AC = 3.76

Answer:

AC = 3.76

Answer:

The distance around the outside of the track is 4183.58m².

Step-by-step explanation:

The area of running track that goes around the field is 9.76m

To proof :

Formula -

(Area of rectangle = length × breadth)

(Area of running track = outside area - inside area)

First case (outside),

length = 73 +2× 9.76

= 92.52m

Breadth = 84.39 m

radius of outside semi circle,

= 46.26m

outside area = area of rectangle + 2 × area of the semi-circle

= 92.52 x 84.39 + 3.14 x 46.26 × 46 × 26

= 7807.76+6719.56

Second case,

radius of the semi-circle,

=36.5m

inside area = area of rectangle + 2x area of the semi-circle

=73x 84.39+ 3.14x 36.5×36.5

= 6160.47 +4183.27

= 10343.74m²

Now,

Area of running track = 14527.32 m²- 10343.74m²

= 4183.58m²

The distance around the outside of track is 4183.58m².

Answer:

m∠XWY = 70°

Explanation:

Two opposite interior angle sum up to one exterior angle on a straight line.

============

? + 45° = 115°

? = 115° - 45°

? = 70°

Answer:

The value of angle XWY = 70°

Step-by-step explanation:

=> angle XYZ + angle XYW = 180° { linear pair }

=> angle XYW + 115° = 180°

=> angle XYW = 180° - 115°

=> angle XYW = 65°

Now angle WXY + angle XWY + angle XYW = 180° { sum of angles of a triangle is 180° }

=> 45° + 65° + angle XWY = 180°

=> angle XWY + 110° = 180°

=> angle XWY = 180° - 110°

=> angle XWY = 70°
