Answer: a=2.72
Explanation:
Move all the terms containing a to the left side of the equation
-0.5a+4.96=3.6
Subtract 4.96 from right side
-0.5a=3.6-4.96
Would be
-0.5a=-1.36
Divide each term by -0.5 and simplify
a= 2.72
Our quadratic polynomial function is:
f(x) = 4x^2 + 2x + 5
our linear binomial form is:
x - a = -2
hence:
a = x + 2
and so we have:
f(x) = 4x^2 + 2x + 5
f(a) = 4(x + 2)^2 + 2<span>(x + 2)</span> + 5
= 4(x^2 + 4x + 4) + 2x + 4 + 5
f(a) = 4x^2 + 18x + 25
X^2+8x-3>-19 | +19
x^2+8x+16>0
x^2+4x+4x+16>0
x(x+4)+4(x+4)>0
(x+4)(x+4)^2>0
this is true cause (X+4)^2 >0 cause X+4>0
Answer:
The temp at sunset was 16 degrees
Step-by-step explanation:
-2 + 18 = 16
The answer is letter a. m∠BAD = 108.42<span>°
The solution is as follows:
If </span>m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° - m∠BCA - <span>m∠BAC
</span>m∠CBA = <span>108.42°
</span>
Since m∠BAD = m∠CBA due to the parallelogram's property,
<span>m∠BAD</span> = <span>108.42°.</span>
