Answer:

y = (3 × 10^8 m/s)/x

Step-by-step explanation:

Speed of a wave is given by the product of wavelength and frequency.

Thus; speed = frequency × wavelength

If x = wavelength and y = frequency then speed will be;

speed = yx

Thus to get wavelength, y;

y = speed/x , but speed is 3 × 10^8 m/s

Thus;

y = (3 × 10^8 m/s)/x

I NEED HELP ASAP PLEASEEEE Evaluate the expression for m = –38. –23(m + 39) =

White raven [17]

Answer: -23

Step-by-step explanation:

Since we are given the value of m, all we have to do is to plug m into the expression and solve.

-23(-38+39) [parenthesis]

-23(1) [multiply]

-23

Now, we know that the expression is -23 when m=-38.

What is the equation of the line in slope-intercept form that passes through point (4, 5) and is parallel to the line y = −2x −

Anestetic [448]

Answer:

$y=-2x+13$

Step-by-step explanation:

Slope-intercept form of a linear equation:

$y=mx+b$

where:

m is the slope
b is the y-intercept

Given equation:

$y=-2x-2$

Therefore, comparing the given equation with the slope-intercept form:

slope (m) = -2
y-intercept (b) = -2

The slopes of parallel lines are equal.

Therefore, the slope of the new line is -2.

Substitute the given point (4, 5) and the slope m = -2 into the slope-intercept formula and solve for b:

$\implies y=mx+b$

$\implies 5=-2(4)+b$

$\implies 5=-8+b$

$\implies b=13$

Finally, substitute the found values of m and b into the formula to create the equation of the line that passes through the given point and is parallel to the given line:

$\implies y=-2x+13$

SURFACE AREAS - PYRAMIDS?

Bond [772]

The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.

$A_{hexagon}=6A_{triangle}=6\cdot \dfrac{1}{2} \cdot \dfrac{a^2\sqrt{3}}{4} =\dfrac{3}{4} \cdot 3^2\cdot \sqrt{3}=\dfrac{27\sqrt{3}}{4}$ sq. cm.

Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is

$A_{lateral}=\dfrac{1}{2}\cdot h\cdot a= \dfrac{1}{2}\cdot 12\cdot 3=18$ sq. cm.

Then the total surface area is:

$A_{total}= \dfrac{27\sqrt{3}}{4} +6\cdot 18=\dfrac{27\sqrt{3}}{4} +108=11.7+108=119.7$ sq. cm.

Answer: 119.7 sq. cm.
