The piecewise relation which defines a function is option B.

A function can be defined as a mathematical expression that defines and represents the relationship between two or more variable.

In Science, there are different types of functions and these include the following;

A piecewise-defined function refers to a type of function that is defined by two (2) or more mathematical expressions (equations) over a specific domain. As an example, we have:

Answer:

71.1 degrees

Step-by-step explanation:

The side opposite angle A is 35 and that adjacent to angle A is 12.  The trig function that connects A and these two sides is

tan A = (opp) / (adj)

which here is

tan A = 35/12.  Find A using a calculator's arctan function:

arctan 35/12 = 1.25 radian or 71.1 degrees.

Answer:

36

Step-by-step explanation:

for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this

1^3 + 2^3 + 3^3

or expanded out

(1x1x1)+(2x2x2)+(3x3x3)

Solving that down, the equation turns into this

1 + 8 + 27

Adding those values together leaves us with 36!

Answer:

36

Step-by-step explanation:

[tex]1^{3}[/tex] + [tex]2^{3}[/tex] +[tex]3^{3}[/tex] = 36

[tex]1^{3}[/tex] = 1 x 1 (= 1) x 1 = 1

The splitted bill of  £180 into a 7 : 5 ratios are  £105 and  £75 respectively.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A bill has to be split £180 in the ratio of 7 : 5.

∴ One part is (7/7 + 5)×180.

= (7/12)×180.

= 105.

Another part is (5/7 + 5)×180.

= (5/12)×180.

= 75.

Answer:

103.75 %

Step-by-step explanation:

[tex] \frac{265.6}{256} \times 100[/tex]

Take 265.6 and divide it by your original number of 256. Now multiply this resultant by 100 to see your final answer rounded to the nearest 10th.

Answer:

256:265*100 =

(256*100):265 =

25600:265 = 96.6

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 265 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=265$100%=265.

Step 4: In the same vein, $x\%=256$x%=256.

Step 5: This gives us a pair of simple equations:

100%=256(1)

x%=256(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%);

100%/x% = 256/256

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=256/256

-->x=96.6%

Therefore, 256 is 96.6% of 265

Third pair of triangles is congruent by SAS.

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

In the third pair, this rule is visible. Two pair of sides are equal to each other and the angles formed at the common vertex of the two sides are equal. Hence, the two triangles are congruent by SAS.

Vertie rode 3.5 kilometers on a bike. His friend Valene rode 2 000
