4. What is the axis of symmetry for h(x) = 19(x – 5)^2 + 6

Mathematics
1 answer:
tester [92]3 years ago
4 0

Answer:

x = 5

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k ) are the coordinates of the vertex and a is a multiplier

h(x) = 19(x - 5)² + 6 ← is in vertex form

with vertex (h, k ) = (5, 6 )

The axis of symmetry is a vertical line passing through the vertex

with equation x = 5

an aquarium has a ratio of 5 rays for every 3 sharks. What percent of this grouping of animals are rays
sashaice [31]

Answer:

62.5%

Step-by-step explanation:

Total number of animals in a group= 5+3=8 animals

Number of rays=5

Since we only have 5 rays out of the total 8, to express the number of rays as a percentage of the total animals, we divide the number of rays by the total animals then multiply by 100 to express in percentage as needed in the question

Percentage of rays=\frac {5}{8}\times 100=62.5

Therefore, the percentage is 62.5%

How much water must be evaporated from 130 gallons of a 9% acid solution to make a 12% acid solution?
Bad White [126]

Answer: 33 gallons

Step-by-step explanation:

We initially have 130 gallons of a 9\% acid solution and we need to change it to a 12\% acid solution, and for that it is necessary to evaporate n gallons of water.

So, this situation can be mathemtically expressed as follows:

(130)(9\%)=(130-n)(12\%)

Then:

(130)(\frac{9}{100})=(130-n)(1\frac{12}{100})

Isolating n:

11.7=15.6-0.12 n

n=32.5 \approx 33

Hence, we need to evaporate 33 gallons of water.
