Answer:

third side is 4

Step-by-step explanation:

using Pythagoras theorem,

(√33)² + l² = 7²

The equation

ra1l [238]

<h2>Explanation:</h2>

Let's use a trial and improvement method to find this solution.

Step 1. Let's choose x = 8.5

Substituting into the equation:

$(8.5)^2+ 3(8.5) - 94=0? \\ \\ 72.25+25.5-94=0? \\ \\ 3.75\neq 0$

Step 2. Let's choose x = 8.4

Substituting into the equation:

$(8.4)^2+ 3(8.4) - 94=0? \\ \\ 70.56+25.2-94=0? \\ \\ 1.76\neq 0$

Step 3. Let's choose x = 8.3

Substituting into the equation:

$(8.3)^2+ 3(8.3) - 94=0? \\ \\ 68.89+24.9-94=0? \\ \\ -0.21\neq 0$

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

$x=8.3$

A tutor gives John 5 assignments and asks him to complete 5. How many possible combinations? Pls answer ASAP

Fittoniya [83]

Answer:

There is 1 possible combination

Step-by-step explanation:

There are 5 assignments and they must be completed. 5. We want to find the number of combinations, then we use the formula of combinations.

$nCr =\frac{n!}{r!(n-r)!}$

Where n is the total number of objects and you choose r from them

Then

$n= 5\\\\r = 5$

$5C5 =\frac{5!}{5!(5-5)!}$

$5C5 =\frac{5!}{5!(0)!}$

$5C5 =\frac{5!}{5!}$

$5C5 =1$
