Find all solutions to the equation. 7 sin2x - 14 sin x + 2 = -5

Alenkinab [10]

7sin²x-14sinx+2= -5
7sin²x-14sinx+7=0
7(sin²x-2sinx+1)=0
sin²x-2sinx+1=0
(sinx-1)(sinx-1)=0
sinx-1=0
sinx=1
$x= \frac{ \pi }{2} +2n \pi$ where n is an integer

Simplify the square root of -72

kupik [55]

Answer:

6i $\sqrt{2}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$ and $\sqrt{-1}$ = i

Given

$\sqrt{-72}$

= $\sqrt{36(2)(-1)}$

= $\sqrt{36}$ × $\sqrt{2}$ × $\sqrt{-1}$

= 6 $\sqrt{2}$ × i

= 6i $\sqrt{2}$

A spider ate 25%25\% 25% 25, percent more bugs this month than last month. The spider ate 88 8 8 bugs last month. How many bugs

alekssr [168]

Answer:

10 bugs

Step-by-step explanation:

If last month the spider ate 8 bugs, and this month the spider ate 25% more bugs, we can calculate the amount of bugs the spider ate this month finding how much is 25% of 8 bugs, and them we sum this value to the 8 bugs it ate last month.

25% of 8 = 8 * 25 / 100 = 2

Now we know that the spider ate 2 more bugs, so the amount of bugs it ate this month is 8 + 2 = 10 bugs.

We can also solve this problem multiplying directly 8 by 1.25 (1.25 represents the 25% increase in the bug consumption):

8 * 1.25 = 10 bugs.
