Mathematics
1 answer:
Elanso [62]3 years ago
3 0

Answer:

The rectangle doesn't exists

Step-by-step explanation:

(4x+3).(x+1)= ?

4x² + 4x + 3x + 3 = ?

4x² + 7x + 3 = ?

4 = a

7 = b

3 = c

delta = b² - 4.a.c

delta = 7² - 4.4.3

delta = 49 - 4.4.3

delta = 49 - 48

delta = 1

x1 = -b + (square root)delta / 2.a

x1 = -7 + 1/2.4

x1 = -6 / 8

x2 = -7 - 1/2.4

x2 = -8/8

x2 = -1

A county's population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponential
aliina [53]
Let t=number of years since 1991.
Then 
P(t)=147 e^(kt)   ... in millions
P(0)=147 e^(0)=147
P(7)=147 e^(7k)=153
e^(7k)=(153/147)
take ln both sides
ln(e^(7k))=ln(153/147)
7k=0.0400 => k=0.005715

Year 2017=>t=2017-1991=26
P(26)=147e^(26*.005715)=170.55
Answer: in 2017, the projected population is 170.55 millions.

kvv77 [185]

Answer:

10/13 = 76.92%

Step-by-step explanation:

The question is missing some information because the underline is missing.

If we make table based on if the letter upper case (A) or lower case(a), and if the letter underlined(B) vs not underlined(b) the data will be:

             A          a

B           4           3         7

b           3           3         6

total      7          6

There are total of 13 letter there. The calculation will be:

P(A or B) = P(A) + P (B) - P(A and B) = (7 + 7 -4) / 13= 10/13 = 76.92%
