can you help with What times 4/5 equals 3/10

Answer:

[tex]x=-4\text{ and } x=3[/tex]

Step-by-step explanation:

We are given the second derivative:

[tex]g''(x)=(x-3)^2(x+4)(x-6)[/tex]

And we want to find its inflection points.

To do so, we will first determine possible inflection points. These occur whenever g''(x) = 0 or is undefined.

Next, we will test values for the intervals. Inflection points occur if and only if the sign changes before and after the point.

So first, finding the zeros, we see that:

[tex]0=(x-3)^2(x+4)(x-6)\Rightarrow x=-4, 3, 6[/tex]

So, we can draw the following number-line:

<----(-4)--------------(3)----(6)---->

Now, we will test values for the intervals x < -4, -4 < x < 3, 3 < x < 6, and x > 6.

Testing for x < -4, we can use -5. So:

[tex]g^\prime^\prime(-5)=(-5-3)^2(-5+4)(-5-6)=704>0[/tex]

Since we acquired a positive result, g(x) is concave up for x < -4.

For -4 < x < 3, we can use 0. So:

[tex]g^\prime^\prime(0)=(0-3)^2(0+4)(0-6)=-216<0[/tex]

Since we acquired a negative result, g(x) is concave down for -4 < x < 3.

And since the sign changed before and after the possible inflection point at x = -4, x = -4 is indeed an inflection point.

For 3 < x < 6, we can use 4. So:

[tex]g^\prime^\prime(4)=(4-3)^2(4+4)(4-6)=-16<0[/tex]

Since we acquired a negative result, g(x) is concave down for 3 < x < 6.

Since the sign didn't change before and after the possible inflection point at x = 3 (it stayed negative both times), x = -3 is not a inflection point.

And finally, for x > 6, we can use 7. So:

[tex]g^\prime^\prime(7)=(7-3)^2(7+4)(7-6)=176>0[/tex]

So, g(x) is concave up for x > 6.

And since we changed signs before and after the inflection point at x = 6, x = 6 is indeed an inflection point.

Answer: a) one central angle is QPR

b) arc QTS is a semicircle

c) arc QR is a major arc

d) arc QTR = 235

e) arc QR = 125

Step-by-step explanation:

A central angle is an angle with its vertex as the midpoint of the circle.

A semicircle is half of a circle. Segment QS goes through the midpoint P splitting the circle in half : arc QTS and arc QRS are both semicircles.

The degree of a central angle is equal to the arc it encompasses. Central angle QPR is equal to 125, therefore arc QR is equal to 125 as well.

Given this information we can now find the remaining arc QTR. A circle is equal to 360 degrees. We know part of the circle is 125 degrees which means the remaking portion must be 235 degrees.

360 - 125 = 235

Using the understanding of trigonometric ratios, cos y = b/6.

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

tan y = a/b

sin y = a/6

tan y = sin y/ cos y

cos y = sin y /tan y = (a/6)/(a/b) = b/6

101+ 6x-5=180

6x=84

x=14

hope this helps!

Answer:

x = 14

Step-by-step explanation:

Since m || n, the two adjacent angles (101° and (6x-5)) must add up to 180°.

180° - 101° = 79°. Therefore, 6x - 5 = 79.

Add 5 to both sides, and the equation is 6x = 84.

Then divide both sides by 6 to get x = 14.

37 pages per hour

Step-by-step explanation:

Given that :

Time Given to read = 45 minutes ; 45 / 60 = 0.75

Number of pages readable ad by Davida within the given time frame = 27 3/4 pages

David's reading rate in pages per hour :

Number of pages read / time taken (hrs)

[27 3/4] ÷ (45/60)

[111 / 4] ÷ (45/60)

(111 / 4 ) * (60/45)

(111 * 60) / (4 * 45)

Answer:

68°

Step-by-step explanation:

A complete angle is 180 degrees, if MNO is 112 degrees, then you will subtract the two numbers to find the angle measure for LMN

180 - 112 = 68

The value of the angle LMN is [tex]68^{0}[/tex]

A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles. The rhombus is also called a diamond or rhombus diamond.

It is given that a rhombus LMNO with one angle MNO measures [tex]112^{0}[/tex].

We need to determine the value of the angle LMN.

Now, we know that the sum of the corresponding angles in the rhombus is always equals to [tex]180^{0}[/tex].

Therefore, angle MNO and angle LMN are the corresponding angles of the rhombus LMNO.

Thus,

Angle MNO + Angle LMN = [tex]180^{0}[/tex]

[tex]112^{0}+Angle LMN = 180^{0}[/tex]

Angle LMN = [tex]180^{0} -112^{0}[/tex]

Angle LMN = [tex]68^{0}[/tex]

Hence, the value of the angle LMN is [tex]68^{0}[/tex].
