OLga [1]3 years ago
8 0

Answer:

z = 1

Step-by-step explanation:

Since this is an equation we can cross multiply the fractions

7/z = 84/12 ➡ 84×z = 7×12

84z = 84 divide both sides by 1

z = 1

Select the true statement. A. Neither function is even. B. Only function f is even. C. Only function g is even. D. Both function
astraxan [27]

Answer:

The answer is "Option C".

Step-by-step explanation:

The graph of the even function will have both ends pointed in the same direction, while the graph of the odd function will have both ends pointed inside the reverse way. Furthermore, as the y-axis approaches, and also regular expression graph becomes symmetric. The graph of an unusual function, on either hand, is symmetric around the origin and also has rotational symmetry around the origin. They could see that the graph of function g meets a function requirement by looking at it. That graph of function f, but on the other hand, is not symmetric about its y-axis, implying that function f is not even. As both a result, g is a function that is even.

Avery planed a circular garden and path as shown below. The radius of the garden is 4feet and the path around the garden is 2 fe
baherus [9]

Answer: The answer, rounded to the nearest tenth, is 113.0

Step-by-step explanation:

This is the formula for calculating the circumference of a circle:

C= 2pi r

R is the radius. Since the path is 2 feet wide, we can add 2 to the radius of the garden to get the radius of the whole path and garden.

2+4=6 so the radius for the total area of the garden and path is 6 feet.

Now we need to plug 6 into the formula to find circumference.

Ed is 7 years older then ted Ed's age is also 3/2 times ted's age how old are ed and ted ​
Rasek [7]

Answer:

if i'm right ted is 14 and ed is 21

Step-by-step explanation:

if ed is 7 years older than ted and is 3/2 times eds age, than we have to find out how much dose 2 represent in the equation 3/2 so we know that ed is seven years older than ted. so that means that if the equation 3/2 was 1/2, 1 would represent 7 years. (i hope your following me) so if 1 represents 7 than 2 must represent 14 and that would be the age of ted because in the equation 3/2 the 2 would represent teds age. and if the 2 represents teds age than 3 would be eds age. so 7 x 3 = 21.  (this is my first time answering a question so sorry if i'm confusing)
