Answer: It's a tie between f(x) and h(x). Both have the same max of y = 3

The highest point shown on the graph of f(x) is at (x,y) = (pi,3). The y value here is y = 3.

For h(x), the max occurs when cosine is at its largest: when cos(x) = 1.
So,
h(x) = 2*cos(x)+1
turns into
h(x) = 2*1+1
h(x) = 2+1
h(x) = 3
showing that h(x) maxes out at y = 3 as well

--------------------------------

Note: g(x) has all of its y values smaller than 0, so there's no way it can have a max y value larger than y = 3. See the attached image to see what this graph would look like if you plotted the 7 points. A parabola seems to form. Note how point D = (-3, -2) is the highest point for g(x). So the max for g(x) is y = -2

15/20 times 1/4 thank me if u like brainly

MaRussiya [10]

Answer: 3/16

Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.

$\frac{15}{20}$ × $\frac{1}{4}$ = ?

15 × 1 = 15

20 × 4 = 80

$\frac{15}{20}$ can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.

15 ÷ 5 = 3

80 ÷ 5 = 16

Therefore, $\frac{15}{20}$ × $\frac{1}{4}$ = $\frac{3}{16}$

Anestetic [448]

Answer:

4n - 4

Step-by-step explanation:

3n-4 = the amount of tickets Evie has

n = the amount of tickets Mark has

3n - 4 + n = 4n - 4

Whats the awenser for (9m - 6)7

svet-max [94.6K]

(9m - 6)7
Distribute 7 to both sides
63m - 42
Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3
