Answer:
1,274
Step-by-step explanation:
5a^4 + 6b^3 when a = 4 and b = -1
~Substitute
5(4)^4 + 6(-1)^3
~Solve the exponents
5(256) + 6(-1)
~Multiply
1280 - 6
~Subtract
1,274
Best of Luck!
Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=4 u
leg₂=7 u
Therefore:
hypotenuse²=(4 u)²+(7 u)²
hypotenuse²=16 u²+49 u²
hypotenuse²=65 u²
hypotenuse=√(65 u²)≈8.06 u
Answer: the length of the hypotenuse is 8.06 u
You basically have to use the quadratic formula to solve this since there are no factors of - 9 which add to give 6.
Then you use
To find which numbers will go into what place inside the quadratic equation.
So a = 1 (because x is alone)
b = 6
c = -9
Then you solve it. I've included a picture of how I did it and I got the answer x=-3+-3sqrt2

<span>The inequality equation that can be used to
express Dexter’s earnings would be “50<e>100”. Since he earns no less
than 50, meaning his earnings cannot be below 50, thus the expression would be “more
than (<)”. In addition, he earns not more than 100, meaning his earnings
would not be above 100, thus the best expression would be “less than (>)”.</span>
