Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.
Which of the following is equivalent to –(4 + (–7))?
–4 + 7
–4 + (–7)
4 + (–7)
–4 – (–7)
Answer:
-4+7, -4 - (-7)
Step-by-step explanation:
The given expression can be simplified:
-(4+(-7)) = -(4-7) = -(-3) = 3
The equivalent choices will all equal 3. Testing each choice:
-4+7 = 3
-4+(-7) = -4-7 = -11
4+(-7) = 4 - 7 = -3
-4 - (-7) = -4 + 7 = 3
Only the first and last choice are equivalent to the original expression.
Factor the expression
Answer:
(2x+1)(x−2)(2x−5)
Step-by-step explanation:
(3x−6)(4x2−1)−(2x−4)(4x2+4x+1)
4x3−16x2+11x+10
=(2x+1)(x−2)(2x−5)

submarine titan descended 93 meters into the ocean to look for fish. Submarine Odyssey descended 3 times as deep. What is Odyssey's depth below sea level in meters?
Answer:
279 meters
Step-by-step explanation:
This is just some simple multiplication. 93*3=279
Submarine Odyssey's depth below sea level is 279 meters.
Given that two submarines titan and odyssey, titan descended 93 meters and odyssey descended 3 times as deep.
We need to find the depth of the submarine odyssey.
To find Odyssey's depth below sea level, we can start by determining the depth that Submarine Titan descended.
According to the given information, Submarine Titan descended 93 meters into the ocean to look for fish.
Now, we need to find the depth that Submarine Odyssey descended, which is three times as deep as Submarine Titan.
We can calculate this by multiplying the depth of Submarine Titan (93 meters) by 3:
Depth of Submarine Odyssey = 93 meters x 3 = 279 meters
Therefore, Submarine Odyssey's depth below sea level is 279 meters.
