No problem. Since the - and + cancel and become a -, you get
3-4
which is -1
Hope this helped.
Answer:
maximum value y = 30
Step-by-step explanation:
Given
- x² + 10x + 5
To complete the square the coefficient of the x² term must be 1
factor out - 1
= - (x² - 10x) + 5
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 10x
= - (x² + 2(- 5)x + 25 - 25) + 5
= - (x - 5)² + 25 + 5
= - (x - 5)² + 30 ← in vertex form
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Hence vertex = (5, 30)
The max/ min occurs at the vertex
Since a < 0 then vertex is a maximum
Hence maximum value is y = 30
Answer:
This means it is between 22000000 m and 44000000 m.
Step-by-step explanation:
From the question, the UAE Hope Pobe is between 22 000 km and 44 000 km away from Mars.
Since,
1 000 m = 1 km
Then,
22 000 km = 22 000 x 1000 m
= 22000000 m
also,
44000 km = 44000 x 1000 m
= 44000000 m
Therefore, the Probe is between 22000000 m and 44000000 m.
No because that would just be measuring freshman a better sampling method would be surveying the same number of students for each grade
Answer:
$3.70
Step-by-step explanation:
$25.30 = 2P + 4D. p for popcorn and d for drinks
P= $5.25
$25.30 = 2($5.25) + 4D
$25.30 = $10.50 + 4D
-10.50. -10.50
inverse operations
$14.80 = 4D
÷4. ÷4
Inverse operations
$3.70 = D
