Answer:

Step-by-step explanation:

The equation of a straight line is :

y=mx+c

where m is the gradient and c is the y-intercept

so if m equals 5 then the gradient is 5

Answer:

gradient = 5

Step-by-step explanation:

The gradient is the coefficient of x, so for y = 5x + 5 it is 5.

(the +5 part is the y-intercept, i.e. where x = 0)

Given that the square root function is only defined for non-negative numbers, define the domain of f in terms of c. {x | ≥ 0}

diamong [38]

Answer:

c:(0;+∞)

Step-by-step explanation:

Given the situation, that the square root function only allows you values above than "0" (not equal neither), then you must consider that every value above 0 belongs to it's domain.

Then, to express the domain, going from your most negative number, to your most possitive number (in this case all positive number, thats why we use infinite) you must use the parenthesis wich means, you are not considering the value (in this case 0), but the value right after it, to the next value that as we said before, is inifinite. Also remember, that when you express a domain, and use infinite (despite it's going to negative way, or possitive way, it also goes with parenthesis).

1+sec^2xsin^2x=sec^2x

Sholpan [36]

1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1

White raven [17]

Answer:

C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}

Step-by-step explanation:

A={x | x is an even integer}

B={x | x is an odd integer},

C={2, 3, 4, 5},

D={8, 9, 10, 11}.

A union of two or more sets is the collection of the members of the sets in a set without repeating any element.

Given sets C and D above, the union of the two sets is the set:

C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}

Note: The Intersection is the collection of sets that are common to C and D. in this case no element is common, therefore the intersection is a Null Set.

What is true regarding two adjacent arcs created by two<br> intersecting diameters?

Juli2301 [7.4K]

Given:

Two diameters intersect each other.

To find:

The correct statement regarding two adjacent arcs created by two intersecting diameters.

Solution:

We know that, two diameter intersect each other at origin and measure of arc is equal to the corresponding angle generated by the intersection of diameters.

If two lines intersect each other then we get 4 angles and sum of any two adjacent angles is 180°.

It means the sum of any two adjacent central angles generated by the intersection of diameters is 180°.

So, the sum of two adjacent arcs created by two intersecting diameters is 180°.

Therefore, the correct option is C.
