Answer:
First angle is 71, and the other is 19
A complementary angle is 90, so 71 + 19 = 90, while having a 52 degree difference
Answer:

Step-by-step explanation:
Given a general quadratic formula given as ax²bx+c = 0
To generate the general formula to solve the quadratic equation, we can use the completing the square method as shown;
Step 1:
Bringing c to the other side
ax²+bx = -c
Dividing through by coefficient of x² which is 'a' will give:
x²+(b/a)x = -c/a
- Completing the square at the left hand side of the equation by adding the square of half the coefficient x i.e (b/2a)² and adding it to both sides of the equation we have:
x²+(b/a)x+(b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a + b²/4a²
- Taking the square root of both sides
√(x+b/2a)² = ±√-c/a + b²/√4a²
x+b/2a = ±√(-4ac+b²)/√4a²
x+b/2a =±√b²-4ac/2a
- Taking b/2a to the other side
x = -b/2a±√√b²-4ac/2a
Taking the LCM:
x = {-b±√b²-4ac}/2a
This gives the vertex form with how it is used to Solve a quadratic equation.
Answer: A.
Step-by-step explanation:
To answer this, you must first understand what fractional exponents mean.
An exponent of 1 is simply the base itself. 7^1 = 7.
An exponent of 2 is squaring the base: 7^2 = 49.
An exponent of 1/2 is taking the square root of the base: 7^(1/2) = sq root of 7
Therefore, an exponent of 1/3 is taking the cube root of the base.
In this case, the base is 2.03 * t.
Therefore, this can be represented as the cube root of the product of 2.03 and the age of the mammal, so the answer is A.
No solution! Hope this helped
