Answer:
b(10) = 76
Step-by-step explanation:
To find b(10) substitute n = 10 into the formula
b(10) = - 5 + 9(10 - 1) = - 5 + 9(9) = - 5 + 81 = 76
Answer:
x=10
Step-by-step explanation:
I think..i tired
Divide both sides by 55.
{x}^{2}=-\frac{500}{5}x2=−5500
2
Simplify \frac{500}{5}5500 to 100100.
{x}^{2}=-100x2=−100
3
Take the square root of both sides.
x=\pm \sqrt{-100}x=±√−100
4
Simplify \sqrt{-100}√−100 to \sqrt{100}\imath√100ı.
x=\pm \sqrt{100}\imathx=±√100ı
5
Since 10\times 10=10010×10=100, the square root of 100100 is 1010.
Answer:
x>4

Answer:
The percentage of her shots that will travel less than 180 yards is approximately 15.9%
Step-by-step explanation:
First it will be required to find the standard or z-score from the following formula
Where:
z = z or standard score
x = value that is observed = 180 yards
μ = Sample mean = 200 yards
σ = Sample standard deviation yards
Plugging the values, we have;
Therefore, the probability that her shots will travel less than 180 is given by the relation;
p( x < 180 yards) = p(z < -1) = 0.15866
Therefore, the percentage of her shots that will travel less than 180 = 0.15866 × 100
= 15.866% ≈ 15.9%.
Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
