Answer:

50

Step-by-step explanation:

a to the power of two plus b to the power of two equals the diagonal squared

a=30

b=40

30*30+40*40= the diagonal squared (d squared)

900+1600=d squared

2500=d squared

d=50

STALIN [3.7K]

Answer:

-40x

Step-by-step explanation:

f(x) =-3x-5

g(x) =4x-2

(f+g)(x) =?

now,

f(g(x))

=f(4x-2)

=-3×4x-2-5

=-10×4x

=-40x

What is the quotient ? a-3/7 divided by 3-a/21
LUCKY_DIMON [66]
Final result :  -3



Step by step solution :Step  1  :            3 - a Simplify   —————             21  Equation at the end of step  1  :  (a - 3)   (3 - a)  ——————— ÷ ———————     7        21   Step  2  :            a - 3 Simplify   —————              7  Equation at the end of step  2  :  (a - 3)   (3 - a)  ——————— ÷ ———————     7        21   Step  3  :         a-3      3-a Divide  ———  by  ———          7       21 
 3.1    Dividing fractions 
To divide fractions, write the divison as multiplication by the reciprocal of the divisor :
a - 3     3 - a       a - 3        21  —————  ÷  —————   =   —————  •  ———————  7        21           7       (3 - a)
 3.2    Rewrite   (3-a)    as  (-1) •  (a-3) Canceling Out : 3.3    Cancel out  (a-3)  which now appears on both sides of the fraction line.
Final result :  -3

Write an equation in slope-intercept form of the line shown.
7nadin3 [17]

Answer:

y = 2x - 5

Step-by-step explanation:

Find the slope using the points, (1, -3) and (3, 1):

slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-3)}{3 - 1} = \frac{4}{2} = 2

m = 2

Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in y = mx + b

-3 = (2)(1) + b

-3 = 2 + b

Subtract 2 from both sides

-3 - 2 = 2 + b - 2

-5 = b

b = -5

Plug in the value of m and b into the slope-intercept form equation, y = mx + b.

Thus:

y = 2x +(-5)

✅y = 2x - 5

A password has to use the following format: LDDDDLLL, where L can be any of the upper case letters in the alphabet, and D can be
maw [93]

Answer:

Only vowels and odd numbers:

P = \frac{5}{26} *\frac{4}{25}* \frac{3}{24}* \frac{2}{23} *\frac{5}{10}* \frac{4}{9} *\frac{3}{8} *\frac{2}{7}

Spells math:

P = \frac{1}{26} *\frac{1}{25}* \frac{1}{24}* \frac{1}{23}

Step-by-step explanation:

We have four letters, so the probability that one letter is a vowel is 5/26 (we have 5 vowels in a total of 26 letters), then the second letter has a probability of 4/25 of being a vowel (1 vowel used), and so on (third letter being vowel = 3/24 and fourth letter being vowel = 2/23)

Then, for the digits, we do the same, one digits has 5/10 probability of being odd, then the second digit has 4/9, the third has 3/8 and the fourth has 2/7.

So the final probability would be:

P = \frac{5}{26} *\frac{4}{25}* \frac{3}{24}* \frac{2}{23} *\frac{5}{10}* \frac{4}{9} *\frac{3}{8} *\frac{2}{7}

To find the probability that the password spells the word “MATH", each letter has to be a specific letter, so the first letter has 1/26 probability, the second has 1/25, and so on:

P = \frac{1}{26} *\frac{1}{25}* \frac{1}{24}* \frac{1}{23}
