Answer:
4 × 10^2 M
Step-by-step explanation:
We are given;
Speed of light as 3.0 × 10^8 m/s
Frequency of radio wave as 7.5 × 10^5 Hz
We are required to determine the wavelength.
Using the formula;
wavelength, λ = v/f
Note; Radio wave is an electromagnetic wave, therefore travels with the speed of light.
Therefore;
wavelength, λ = 3.0 × 10^8 m/s ÷ 7.5 × 10^5 Hz
= 4 × 10^2 M
Hence, the wavelength of the radio wave is 4 × 10^2 M
Y+2x=24
product is max
xy=max
we have
y+2x=24
minus 2x both sides
y=24-2x
sub that for y in xy=max
(24-2x)(x)=max
-2x^2+24x=max
we have a parabola opening down
the coordinates of the vertex is our answer
the x value of the vertex is -b/2a where
ax^2+bx+c=y
-24/2(-2)=-24/-4=6
xvalue=6
we can just sub
y=24-2x
y=24-2(6)
y=24-12
y=12
the numbers are 6 and 12
the product is 72
the numbers are 6 and 12
Answer:
- 7/10
Step-by-step explanation:
There you go hope alls well.
Because base angles are congruent, both angle A and B are congruent. If the two triangles are congruent, then the base angles are the same, meaning 5x=50*. Divide by 10 and you get the answer of x=5. :) Hope this helps!
203 is the answer there you go
