Answer:

4.50 or 4.5. The only reason you got it wrong was because you didn't round to the nearest hundredth. 4.499 rounds up to 4.50

Step-by-step explanation:

Hopefully you know what the sine and cosine functions are...

So you gotta use the sine function for this equation since you are given the hypotenuse and B.

$sine(40)=\frac{x}{7}$

We put the degree measure next to sine because there can only be one unknown

So we can solve from here by multiplying both sides by 7

$(7)sine(40)=x$

Now put your calculator in the degree mode and insert this equation into it.

You get 4.499 rounded to the nearest hundredth is 4.50

Rufina [12.5K]

Answer:

It would take 22 seconds to walk from one end of sidewalk to the other.

Step-by-step explanation:

i) distance from the shopping area to the parking garage = 220 feet

ii) normal walking rate = 6 ft / second

iii) moving sidewalk = 4 ft/second

iv) total speed therefore = 6 + 4 = 10 ft/second

v) number of seconds to walk from one end of sidewalk to the other

= 220 ft / (10 ft/second) = 22 seconds.

Solve the volume formula V= /wh for h.

Sladkaya [172]

Answer:

V = lwh

/lw /lw

First isolate the variable by seperating lw from the side that h is on. You do this by dividing both sides by lw. This will result in h being volume over lenght and width.

(e) The number of bees spotted in Amelie's garden can also be modeled by the function B(x) = 50√ k + 2x where x is the daily hig

Lunna [17]

Answer:

$\frac{dB}{dt}=4$

Step-by-step explanation:

Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.

Given:

Number of bees is modeled by the function $B(x)=50\sqrt{k}+2x$

The daily high temperature is increasing at a rate of 2 °F per day when the number of bees spotted is 100.

To find:

rate of change of number of bees when 100 bees are spotted

Solution:

$B(x)=50\sqrt{k}+2x$

Differentiate with respect to t,

$\frac{dB}{dt}=0+2(\frac{dx}{dt}) \\\frac{dB}{dt}=2(\frac{dx}{dt}) \\$

Put $(\frac{dx}{dt}) =2$

$\frac{dB}{dt}=2(2)=4$

At x = 100, $\frac{dB}{dt}=4$

Which Greek mathematician wrote the most definitive text on geometry, one that is still referred to today?

frutty [35]

The Greek mathematician who wrote the most definitive text on geometry, one that is still referred to today is Euclid. Euclid of Alexandria is also called "Father of Geometry". He was a great Greek mathematician. Euclidean geometry is still widely taught in schools and colleges. I hope the answer comes to your help.
