After checking with each triplet whether they form a Pythagorean triplet, we find that D) [10, 24, 26] is the only one that applies with the triplet.

The ratio 2:7. Add 7 and 2 together to get 9. Then divide 243 by 9 which is 27. 27x2 is 54 so. There was 54 students out of state. And 189 that were in state

Which of there polynomials could have (x-2) as a factor?

sertanlavr [38]

Answer:

x-2 is a factor of following polynomials:

b(x) = 3x² + 15x - 42
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70

Step-by-step explanation:

In order to check that which polynomials might have x-2 as a factor, we will put

x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.

So,

a(x) = 6x² - 7x - 5

Putting x = 2

$a(2) = 6(2)^2-7(2)-5\\= 6(4)-14-5\\=24-14-5\\=24-19\\=5 \neq 0$

b(x) = 3x² + 15x - 42

$b(2) = 3(2)^2 + 15(2) - 42\\=3(4)+30-42\\=12+30-42\\=42-42 = 0$

c(x) = 2x³ + 13x² + 16x + 5

$c(2) = 2(2)^3 + 13(2)^2 + 16(2) + 5\\=2(8)+13(4)+32+5\\=16+52+32+5\\=105 \neq 0$

d(x) = 3x³ - 2x² - 15x + 14

$d(2) = 3(2)^3 - 2(2)^2 - 15(2) + 14\\= 3(8)-2(4)-30+14\\=24-8-30+14\\=38-38 = 0$

e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70

$e(2) = 8(2)^4 - 41(2)^3 - 18(2)^2 + 101(2) + 70\\= 8(16)-41(8)-18(4)+202+70\\=128-328-72+202+70\\=0$

$f(2) = (2)^4 + 5(2)^3 - 27(2)^2 - 101(2) - 70\\=16+5(8)-27(4)-202-70\\=16+40-108-202-70\\=-324 \neq 0$

Hence,

x-2 is a factor of following polynomials:

b(x) = 3x² + 15x - 42
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70

What is the solution to 2log↓g(x)=log↓g8+log↓g(x-2)?

trapecia [35]

Answer:

x = 4

Step-by-step explanation:

$2log_9(x)=log_98+log_9(x-2) \\ log_9( {x}^{2} )=log_9 \{8 \times (x-2) \} \\ {x}^{2} =8 \times (x-2) \\ {x}^{2} = 8x - 16 \\ {x}^{2} - 8x + 16 = 0 \\ (x - 4)^{2} = 0 \\ x - 4 = 0 \\ \huge \red { \boxed{x = 4}}$
