Answer:

Step-by-step explanation:

recall that the point-slope form of a linear equation is given by

y = mx + c

Rearranging so that it is in the same form as the answer choices, we get

y = c + mx

where m is the slope and c is the y-intercept

we note the following observations

1) The line goes from top left to bottom right, this means that the slope is negative, hence m has to be negative. (in our case, all the choices have negative x)

2) The line crosses the y-axis at y = 4, this means the y-intercept is 4 and hence c = 4.

If we look at the choices, only choice B satisfies both observations (that m is negative and c = 4)

what is (5.91 x 10^-3) - (8.7 x 10^10) written in a scientific notation? Please answer asap thank you :))

nata0808 [166]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

$\left(5.91\times \:10^{-3}\right)-\left(8.7\times \:10^{10}\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$=5.91\times \:10^{-3}-8.7\times \:10^{10}$

$5.91\times \:10^{-3}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}$

$=5.91\times \frac{1}{10^3}$

$=\frac{5.91}{1000}$

$=0.00591$

similarly

$8.7\times \:10^{10}$

Convert element to a decimal form

$10^{10}=10000000000$

$=10000000000\times \:8.7$

$\mathrm{Multiply\:the\:numbers:}\:8.7\times \:10000000000=87000000000$

$=87000000000$

Thus, the expression becomes

$\left(5.91\times \:\:10^{-3}\right)-\left(8.7\times \:\:10^{10}\right)=5.91\times \:\:10^{-3}-8.7\times \:\:10^{10}$

$=0.00591-87000000000$

$=-86999999999.9941$

Hence,

converting -86999999999.9941 in a scientific notation

In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:

−86999999999.9941 ⟶ 86999999999.9941

In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:

8.6999999999.9941

So, we need to move the decimal point 10 places to the right.

This means that the power of 10 will be positive 10.

Now we have that the

Number part = 8.69999999999941 and

Exponent part = 10

Thus, we conclude that:

−86999999999.9941 = − 8.69999999999941 × 10¹⁰

A company is worth $79,600,000. Write this number in scientific notation. 79,600,000=

Alina [70]

Answer:

The answer is 7.96×10⁷ .

Step-by-step explanation:

As the decimal moves to the left , you have to add one more power to the base 10 :

e.g

7 960 000.0 = 7 960 000×10¹

796 000.00 = 796 000×10²

79 600.000 = 79 600×10³

7 960.0000 = 7 960×10⁴

796.00000 = 796×10⁵

79.600000 = 79.6×10⁶

7.9600000 = 7.96×10⁷

* Take note :

$a \times {10}^{n}$

0 < a < 10 ('a' must be greater than 0 but smaller than 10)

Solve the triangle. A = 46° a = 33 b = 26

frozen [14]

Using sin rule:
a/sin A =b/sin B=c/sin c
SIN A=sin 46=0.72
THEN:sin B =(0.72*26)/33=0.57
then B= 34°
AS the sum of triangle angles=180
then C=180-(46+34)=100°
then c =(a*sin C)/sin A
sin C=sin 100=0.98
=(33*0.98)*0.72=45
