If cos x = .34, what is sin x?

1 answer:

6 0

Use the formula:
$\sin^2 x + \cos^2 x = 1$
$\sin^2 x + (0.34)^2 = 1$
$\sin^2 x = 1-0.34^2 = 0.8844$
$\sin x =\pm 0.9404$

Help Please.. 1 /2x + y = 4 What is the x-intercept? What is the y-intercept?

IgorC [24]

Answer:

x - intercept = 8

y - intercept = 4

Step-by-step explanation:

In order to to find x- intercept, plug y = 0, in the given equation of line.

$\frac{1} {2} x+y = 4\\\\\frac{1} {2} x+0 = 4..(plug \: y = 0)\\\frac{1} {2} x = 4\\x = 2\times 4\\x = 8\\\huge \red {\boxed {\therefore x-intercept = 8}}$

In order to to find y- intercept, plug x = 0, in the given equation of line.

$\frac{1} {2} x+y = 4\\\\\frac{1} {2} \times 0+y = 4..(plug \: x = 0)\\0+y = 4\\y = 4\\\huge \purple {\boxed {\therefore y-intercept = 4}}$

Large Number Calculations

pantera1 [17]

Answer:

19.2 kg

Step-by-step explanation:

Amount of Bananas consumed in US per year = 5.77 million metric tons

Since 1 million = $10^{6}$ and 1 metric ton = 1000 kg, we can write:

Amount of Bananas consumed in US per year = $5.77 \times 10^{6}$ metric tons

Amount of Bananas consumed in US per year = $5.77 \times 10^{6} \times 1000 = 5.77 \times 10^{9}$ kg

Number of people in US = 301 million = $301 \times 10^{6}= 3.01 \times 10^{8}$

We have to find how many kilograms of bananas are consumed per person in 1 year in US. For this we have to divide the total amount of bananas eaten in US per year with total number of people in US, which will be:

$\frac{5.77 \times 10^{9}}{3.01 \times 10^{8}} \\\\ = 19.2$

This means, 19.2 kilograms of bananas are eaten in US per person in a year.

Jane says that she can use addition to show that the graphs of 2x - 3y = 1 and 2x + 3y = 2 are intersecting lines. In two or mor

iogann1982 [59]

For this case we have the following equations:
2x - 3y = 1
2x + 3y = 2
When adding both equations we observe that:
Sentence 1: we have an equation of a variable, which in this case will be x. We can clear the value of x.
Sentence 2: Knowing the value of x, we can substitute in any equation and find the value of y.
Sentence 3: The value of x and y represents the point of intersection of both lines (x, y).
