What error did Maria likely make?

raketka [301]

She didn’t notice that the 3 and the 4 both do not have the variable “n” with them
She just added up all the numbers together then added the variable at the end.

Please help. I need this answer, thanks if you answered. Also please be correct

-Dominant- [34]

The correct answer is 5/7 and 5/4.

We have given that the expression

$a. \frac{2}{7}+\frac{3}{7}$

$b. 2\times \frac{1}{4} +\frac{3}{4}$

<h3>What is the dividando and componendo?</h3>

Components and dividend is a theorem on proportions that allows for a quick way to perform calculations and reduce the number of expansions needed. It is particularly useful when dealing with equations involving fractions or rational functions in mathematical Olympiads, especially when you see fractions.

We have to determine the value of the given expression,

$=\frac{2}{7}+\frac{3}{7} \\=\frac{5}{7}$

Similarly, for the second equation, we get,

$b. 2\times \frac{1}{4} +\frac{3}{4}\\=\frac{2}{4} +\frac{3}{4}\\=\frac{5}{4}$

Therefore the correct answer is 5/7 and 5/4.

In circle F with m \angle EFG= 122m∠EFG=122 and EF=16EF=16 units, find the length of arc EG. Round to the nearest hundredth.

kow [346]

Given:

In circle F, $m\angle EFG=122^\circ,\ EF=16$ units.

To find:

The length of arc EG.

Solution:

It is given that, $m\angle EFG=122^\circ,\ EF=16$ units. It means the central angle of arc EG is 122 degrees and the radius of the circle F is 16 units.

Formula for arc length is:

$s=2\pi r\times \dfrac{\theta}{360^\circ }$

Where, r is the radius and $\theta$ is the central angle in degrees.

Putting $r=16,\ \theta=122^\circ,\ \pi=3.14$ , we get

$s=2(3.14)(16)\times \dfrac{122^\circ}{360^\circ }$

$s=100.48\times \dfrac{61}{180}$

$s=34.0515556$

$s\approx 34.05$

Therefore, the length of arc EG is 34.05 units.

Write an equation for each translation of y=|x| .

bija089 [108]

Answer:

y = |x| -13

Step-by-step explanation:

recall for any function y = f(x), to translate the function vertically by any value "a", we simply have to add "a" to f(x).

If a is positive, then the graph is translated in the positive y-direction (i.e upwards), if a is negative, then the graph is translated in the negative y-direction (i.e downwards)

In our case , the graph is translated vertically by 13 units (i.e a = 13) and it is to be translated downwards (i.e negative)

hence we add a= -13 to the original function.

y = f(x) + (-13)

y = |x| + (-13)

y = |x| -13
