We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:

\dfrac{1}{2} \times \dfrac{\sqrt{98}}{7}

We can rewrite 98 into 2 \times 49

\dfrac{1}{2} \times \dfrac{\sqrt{2 \times 49}}{7}

=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times \sqrt{49}}{7}

The square root of 49 is 7

=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times 7}{7}

=\dfrac{1}{2} \times\sqrt{2}

=\dfrac{\sqrt{2}}{2}

This should be your answer. Let me know if you need any clarifications, thanks!

Answer:

√2/2

Step-by-step explanation:

Reciprocal of 7/sqrt(98) = sqrt(98)/7 = √98/7

One-half of the reciprocal = 1/2 × √98/7 = √98/14 = 7√2/14 = √2/2

Someone please help I don’t understand!!!
Fantom [35]

Answer:

y=3

Step-by-step explanation:

This is because it is a straight line, there is no need for x-intercepts or y-intercepts because it already intercepts y at y=3.So, your answer is y=3

Find the value of x.
Leya [2.2K]

9514 1404 393

Answer:

  120°

Step-by-step explanation:

There are several ways you can redraw this figure to help you find the value of x. One of them is to draw a line perpendicular to the parallel lines, intersecting the vertices of the given angles*. Then the interior angles of the triangle formed will be ...

  125° -90° = 35°

  115° -90° = 25°

The angle that is a vertical angle with x is the third angle of the triangle, so its measure is ...

  x = 180° -35° -25° = 120°

The value of x is 120°.

The curve with equation y2 = 5x4 − x2 is called a kampyle of eudoxus. find an equation of the tangent line to this curve at the
Vesnalui [34]
To find the tangent line we will need the slope of the tangent at x=-1 (the x-coordinate of the point given). We find the slope by using the derivative of the curve.

Th curve given is y^{2} =5 x^{4} - x^{2} which can be solved for y by taking the root of both sides. We obtain y=(5 x^{4}- x^{2} ) ^{1/2}

We find the derivative using the chain rule. Bring down the exponent, keep the expression in the parenthesis, raise it to 1/2 - 1 and then take the derivative of what is inside.

y’=(1/2)(5 x^{4} - x^{2} )^{-1/2}(20 x^{3} -2x)

Next we evaluate this expression for x=-1 and obtain:
\frac{20(-1)^{3} -(2)(-1)}{2 \sqrt{5(-1 ^{4}-(-1 ^{2})  } }= \frac{-20+2}{2 \sqrt{5-1} }=-18/4=-9/2

So we are looking for a line through (-1,2) with slope equal to -9/2. We use y=mx+b with m=-9/2, x=-1 and y=2 to find b.

2=(-9/2)(-1)+b
2-(9/2)=b
b=-5/2

So the tangent line is given by y=(-9/2)x+(-5/2)

Line p is parallel to line q. If the measure of angle 3 is 54 what is the measure of angle 6?... Help
inn [45]

Answer:

54°

Step-by-step explanation:

Because p and q are parallel, angle 3 equal to angle 6 as they are alternative angles.

So angle 6 is <u>54°</u>.

Alternative

Line p and line q is parallel, so that the sum of a pair of interior angles (angle 3 and angle 5, angle 4 and angle 6) are equal to 180°.

So angle 4 + angle 6 = 180°.

Find angle 4 first:

180° - angle 3 = angle 4

180° - 54° = 126°

So the measure of angle 6 is

180° - 126° = <u>54°</u>
