Tan x = -0.25 for 0< x < 720​

Mathematics
1 answer:
grigory [225]4 years ago
3 0

Answer:

Below in bold.

Step-by-step explanation:

The smallest angle for which -0.25 is the tangent is in the  second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.

So for the range 0 to 720, x = 165.96, 345.96 and  360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.

In the figure, angle B measures 44°, angle A measures 62°, and angle E measures 50°.
Gre4nikov [31]
We don't need the figure
angle b = 44 degrees
angle a = 62 degrees
angle e = 50 degrees
angle f = unknown
we know that 
angle a + b + e + f = 180 degrees
50 + 44 + 62 + f =180 degrees
f= 180-50-44-62
but here there is only one blank so we have to add 44 and 62 to make one number that is 106
therefore, f = 180-50-106
if you further want to solve it angle f is 24

-3,6,-9,12,-15 which of the following represents the general term for the sequence give?
Mademuasel [1]

The general term for the sequence a_{n}=(-1)^{n} 3 n

<h3><u>Solution:</u></h3>

Given sequence is -3, 6, -9, 12, -15

We have to find the general term of sequence

The terms in the sequence are found out by using the recursive definition:

a_{n}=(-1)^{n} 3 n

Let us use this definition to find out the terms and check if it matches our given sequence

\begin{array}{l}{\text { For } n=1:-(-1)^{n} 3 n=(-1)^{1} \times 3 \times 1=-3} \\\\ {\text { For } n=2:-(-1)^{n} 3 n=(-1)^{2} \times 3 \times 2=1 \times 6=6} \\\\ {\text { For } n=3:-(-1)^{n} 3 n=(-1)^{3} \times 3 \times 3=-1 \times 9=-9} \\\\ {\text { For } n=4:-(-1)^{n} 3 n=(-1)^{4} \times 3 \times 4=1 \times 12=12} \\\\ {\text { For } n=5:-(-1)^{n} 3 n=(-1)^{5} \times 3 \times 5=-1 \times 15=-15}\end{array}

Thus the general term is given by a_{n}=(-1)^{n} 3 n

En una empresa se realizan dos descuentos sucesivos : el primero del 30% y luego otro del 10% para la venta de sus artículos ¿ c
FromTheMoon [43]

If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.

<h3>What was the equivalent discount?</h3>

Assume that the price of a good in the company was $10.

The initial discount of 30% takes the price to:

= 10 x ( 1  - 30%)

= $7

Then there is a 10% discount:

= 7 x (1 - 10%)

= $6.30

The equivalent discount is:

= (10 - 6.3) / 10

= 37%
