Mathematics
1 answer:
aleksley [76]3 years ago
5 0

Answer:

BC=5

Step-by-step explanation:

4/10=x/x+3

4(x+3)=10x

4x+12=10x

subtract 4x from each side

6x=12

divide both sides by 6

6x/6=12/6

x=2

BC=x+3

substitute for x

BC=2+3

BC=5

What is the rate of change for the function f(x)=2x-3
Stolb23 [73]

Answer:

2

Step-by-step explanation:

f(x) = 2x - 3 is a linear function

The rate of change of a linear function is the measure of the slope.

The equation is in slope- intercept form, that is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 3 has slope m = 2

Thus rate of change = 2

PSYCHO15rus [73]

Answer:

in triangle BCD

relationship between base and hypotenuse is given by cos angle

cos 71=b/h

cos71=BD/BC

cos71=67/x

x=67/cos71=205.8ft.

the length of BC to the nearest tenth of a foot is 206ft.
