bulgar [2K]

Answer: (a,a)


Step-by-step explanation:

Given: A  right isosceles triangle which is placed on the coordinate plane such that one of the legs of the triangle lies along the x-axis and the other leg is parallel to the y-axis.

From the given figure one vertex is on origin(0,0) and second on x -axis as (a,0) .ii.e. one side of the triangle is on the x axis with length 'a' and the side parallel to the y axis should perpendicular to the x axis with length 'a'.(∵ two sides are equal in a right isosceles triangle)

So the coordinates should she assign to the third vertex of the right isosceles triangle is (a,a).[as the point lie above the point (a,0), so its x abscissa should be same]

pshichka [43]

Answer: A. Approximately 0.017 pounds

Step-by-step explanation:

Formula to find the margin of error :

E=z^*\dfrac{s}{\sqrt{n}} , where z* = critical value for confidence interval , s= standard deviation , n= sample size.

As per given , we have

s= 0.15 pound

n= 300

Critical value for 95% confidence = 1.96

Then, Margin of error for 9%% confidence interval will be :

E=(1.96)\dfrac{0.15}{\sqrt{300}}\\\\=0.0169740979142\approx0.017

Hence, they can expect a margin error of 0.017 pound (approximately.)

Thus , the correct answer is A. Approximately 0.017 pounds

Write the slope-intercept form of the equation that passes through the point (1,5) and is perpendicular to the line y =-x + 3
Diano4ka-milaya [45]

Answer:

y = -1/7x - 23/7

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (-4 + 3)/(5 + 2)

m = -1/7

y = -1/7x + b

Step 2: Find <em>b</em>

-3 = -1/7(-2) + b

-3 = 2/7 + b

b = -23/7

Step 3: Rewrite equation

y = -1/7x - 23/7

Enter in standard form the equation of the line passing through the given point and having the given slope.
Olin [163]
M = -2/3,   B(2, -5),   x₁ = 2, y₁ = -5

y - y₁ = m(x - <span>x₁)

</span>y - -5 = -(2/3)(x - 2<span>)
</span>
3(y + 5) = -2(x - 2)

3y + 15 = -2x + 4

3y + 2x = 4 - 15

3y + 2x = -11
