Answer:
let the numbers be x and y then by given conditions:
x + y = 10 ….. eq 1
and
xy = 9….. eq 2
from eq 2. y = 9/x
put this in eq. 1
x + 9/x = 10
x + 9= 10x
x = 1
now,
xy = 9put value of x
y = 9

Answer:
❝ D. 13 feet ❞
Step-by-step explanation:
Here,
- Window is in the rectangular shape.
- Measure of its one diagonal is 13 feet.
According to the properties of rectangle,
→ Diagonals of a rectangle are equal.
So, here the length of other diagonal will be 13 feet too.
Answer:
Hence x = y = 2
Step-by-step explanation:
Using the SOH CAH TOA identity
Hypotenuse = 2√2
Opposite = x
theta = 45
Sin theta = opp/hyp
Sin 45 =x/2√2
1/√2 = x/2√2
x = 2√2 * 1/√2
x = 2
To get y we will use the pythagoras theorem;
(2√2)² = x² +y²
(2√2)² = 2²+y²
8 = 4 + y²
y² = 8-4
y² = 4
y = √4
y = 2
Hence x = y = 2
Answer:
Miles in 10 gallons = 195
Miles in 1 gallon = 195/10 = <u>1</u><u>9</u><u>.</u><u>5</u>
Miles in 18 gallons = 19.5 × 18 = <u>3</u><u>5</u><u>1</u><u> </u><u>miles</u><u>.</u>
Set the function to equal zero:
To find the zeros, or solutions, to this problem, we will use the quadratic formula:
Plug the values into the equation:
Solve for both plus and minus:
The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.
The answer is
'<span>
x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.</span>
