Mathematics

Answer:

\frac{21}{2} units²

Step-by-step explanation:

D and E lie on the x- axis and F is vertically below D

The triangle formed is right at D with legs of length 3 and 7

The area (A) of a right triangle is found using the formula

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = 3 and h = 7, hence

A = \frac{1}{2} × 3 × 7 = \frac{21}{2} units ²

Which inequality is represented by the graph?
PSYCHO15rus [73]

Answer:

<h2>NONE OF THEM</h2>

Step-by-step explanation:

From the graph,

y and x intercepts are (0,-3) and approximately (1.9,0) respectively

for A, C and D : y=53x-3

x intercept the value of y=0, and y intercept x=0.

x and y intercepts are (\frac{3}{53},0 ) and approximately (0,-3) respectively

for B: y=35x-5

 x and y intercepts are (\frac{3}{35},0 ) and approximately (0,-3) respectively

Therefore x and y intercepts for the lines y\leq 53x-3,y>53x-3, y and y they are not equal to the x and y intercepts of the given graph

If an airplanes speed is 850mi/h what is it’s speed in m/s
Blizzard [7]

we are given

speed is 850mi/h

we know that

1 mile =1609.34 metre

1 hour = 3600 second

now, we can replace 1mi and 1hour

850mi/h=850*\frac{1609.34}{3600} m/s

now, we can solve it

379.98306

850mi/h=379.98306 m/s...........Answer
