Answer:

See below.

Step-by-step explanation:

The answer is C.

The slopes are different, so they would have to intersect at some point. If they were the same, they either would have no solutions or infinite solutions.

Write an inequality for the given graph.

Gekata [30.6K]

Answer:

$y$

Step-by-step explanation:

<em>Find the equation of the dashed line</em>

The line pass through the points

$A(0,-3)$ -----> is the y-intercept of the line

$B(6,0)$

Find the slope of the line m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{0+3}{6-0}=0.5$

Remember that

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=0.5$

$b=-3$

substitute

$y=0.5x-3$

<em>Find the inequality</em>

we know that

The solution of the inequality is the shaded area below the dashed line

$y$

olchik [2.2K]

Write and solve an equation of ratios:

5 *10^9 years 100 m
------------------- = --------------
5 * 10^3 yrs x

Reducing the first fraction,

100 m
10^6 = ----------
x
100 m
Solving for x, x = ------------- = 10^(-4) m, or [10^(-1)] * [10^(-3))]
10^6
this comes out to one tenth of 1 millimeter.

Inessa [10]

Answer:

Ginni and Waren

Step-by-step explanation:

Here both Ginni and ware are partners in the Company after a year when ginni founded it.

Both Ginni and Waren are risk, because both the partners have unlimited personal liability so it does not matter who owns the larger share of the company. The risk will be equal on both the partners whereas Phebe here is at the least risk .

Evaluate the following integral using trigonometric substitution.

wariber [46]

Answer:

Step-by-step explanation:

1. Given the integral function $\int\limits {\sqrt{a^{2} -x^{2} } } \, dx$ , using trigonometric substitution, the substitution that will be most helpful in this case is substituting x as $asin \theta$ i.e $x = a sin\theta$ .

All integrals in the form $\int\limits {\sqrt{a^{2} -x^{2} } } \, dx$ are always evaluated using the substitute given where 'a' is any constant.

From the given integral, $\int\limits {7\sqrt{49-x^{2} } } \, dx = \int\limits {7\sqrt{7^{2} -x^{2} } } \, dx$ where a = 7 in this case.

The substitute will therefore be $x = 7 sin\theta$

2.) Given $x = 7 sin\theta$

$\frac{dx}{d \theta} = 7cos \theta$

cross multiplying

$dx = 7cos\theta d\theta$

3.) Rewriting the given integral using the substiution will result into;

$\int\limits {7\sqrt{49-x^{2} } } \, dx \\= \int\limits {7\sqrt{7^{2} -x^{2} } } \, dx\\= \int\limits {7\sqrt{7^{2} -(7sin\theta)^{2} } } \, dx\\= \int\limits {7\sqrt{7^{2} -49sin^{2}\theta } } \, dx\\= \int\limits {7\sqrt{49(1-sin^{2}\theta)} } } \, dx\\= \int\limits {7\sqrt{49(cos^{2}\theta)} } } \, dx\\since\ dx = 7cos\theta d\theta\\= \int\limits {7\sqrt{49(cos^{2}\theta)} } } \, 7cos\theta d\theta\\= \int\limits {7\{7(cos\theta)} }}} \, 7cos\theta d\theta\\$

$= \int\limits343 cos^{2} \theta \, d\theta$
