Guys, I really need help!

Mathematics
1 answer:
TiliK225 [7]2 years ago
4 0

Answer:

The answer is

p =  \frac{ - 3}{1000} n + 97

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

m =  \frac{91 - 82}{2000 - 5000}  =  \frac{ - 3}{1000}  \\ to \: find \: the \: b \\ 91 =  \frac{ - 3}{1000}  \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \:  \\ p =  \frac{ - 3}{1000} n + 97

In ABC, BC=4 cm, angle b=angle c, and angle a=20 degrees, what is ac to two decimal places
zubka84 [21]

Answer:

Therefore,

AC=11.52\ cm

Step-by-step explanation:

Given:

In ΔABC, BC=4 cm,

angle b=angle c, and

angle a=20°

To Find:;

AC = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

\angle a+\angle b+\angle c=180\\\therefore 2m\angle b =180-20=160\\m\angle b=\dfrac{160}{2}=80\°

We know in a Triangle Sine Rule Says that,  

In Δ ABC,

\dfrac{a}{\sin A}= \dfrac{b}{\sin b}= \dfrac{c}{\sin C}

substituting the given values we get

\dfrac{BC}{\sin a}= \dfrac{AC}{\sin b}

\dfrac{4}{\sin 20}= \dfrac{AC}{\sin 80}\\\\AC=11.517=11.52\ cm

Therefore,

AC=11.52\ cm

Please what is the solution for the question above.......
Ivanshal [37]

Answer:

A

Step-by-step explanation:

simple interest (I) is calculated as

I = \frac{PRT}{100}

P is the principal. R the rate of interest and T the time in years

Here P = 880000, R = 3.5 and T = 2.5 , then

I = \frac{880000(3.5)(2.5)}{100}

 = 8800 × 3.5 × 2.5

 = 77000 → A
