A line segment ad, contains points b & c such that c is between a and d, and b is between a and

1 answer:

3 0

If you drew out this line segment with the points in the order we are given them, the segment would be labeled as a, b, c, d in that order. We are given a measure for ab, and we are also given a measure for bd with c being ignored for a minute. The entire length of the segment can be found by adding ab and bd. 6 + 23 = ad and ad = 29. So the length of the whole segment is 29. We have the length of cd given to be equal to ab, so cd = 6. ab + bc + cd = ad and we are looking for bc. Since we have the other lengths and the length of the whole segment, we fill in accordingly: 6 + bc + 6 = 29. Solving for bc we get bc = 17.

A curve has equation y=x√x.find the equation of the tangent to the curve at the point(1, 5)

rewona [7]

Answer:

y - 5 = $\frac{3}{2}$ (x - 1)

Step-by-step explanation:

Note that $\frac{dy}{dx}$ = $m_{tangent}$

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x $\sqrt{x}$ = x. $x^{\frac{1}{2} }$ = $x^{\frac{3}{2} }$ , then

$\frac{dy}{dx}$ = $\frac{3}{2}$ $x^{\frac{1}{2} }$

When x = 1

$\frac{dy}{dx}$ = $\frac{3}{2}$ . 1 = $\frac{3}{2}$

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = $\frac{3}{2}$ and (a, b) = (1, 5), thus

y - 5 = $\frac{3}{2}$ (x - 1) ← equation of tangent

Jorge got a hit 8/25 of the times that he

kondor19780726 [428]

Answer:

32%

Step-by-step explanation:

Percent means out of 100 so we need the denominator to be 100

8/25 * 4/4 = 32/100

The percent is the numerator since it is now out of 100

Tourists from a tour bus were asked about places they visited during their stay in a city. The results are shown in the table.

denis23 [38]

So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo.
Hope this helps!
