Answer:

d) 5.88 × 10⁻⁹

Explanation:

\rightarrow \sf \left(1.2\cdot 10^7\right)\left(4.9\cdot 10^2\right)

\sf apply \ exponent \ rule : a^b + a^c = a^{b + c}

\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^{7}\cdot \:10^{2}

\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^{7+2}

\rightarrow \sf 1.2\cdot \:4.9\cdot \:10^9

\rightarrow \sf 5.88 \cdot \:10^9

Compute the value of the discriminant and give the number of real solutions of the quadratic equation. -9x to the second power-6
Step2247 [10]
Answer:
discriminant=0
Number of real solutions=1


Step-by-step explanation:

Given the equation:
-9x^2-6x-1=0
Let a: coefficient of x^2
Let b: coefficient of x
Let c: constant
a=-9
b=-6
c=-1
The formula of the discriminant is given by:
discriminant= b^2 - 4ac
discriminant= (-6)^2 - 4(-9)(-1)
= 36 - 36 = 0
We know that:
If discriminant<0 then the equation has no real root
If discriminant=0 the equation has one real root
If discriminant>0 the equation has 2 real roots

Here we got discriminant=0 so the quadratic equation has 1 real root.
