Hi there!
b=3·b=3b
This means:
1=3, 2=6, 3=9, 4=12, 5=15, 6=18, 7=21, 8=24, and 9=27.
Multiply by 3 everytime...
if b is 3, then the expression is is 3·b or 3b.
Final Result: 3b
As, we are given :
Minutes taken to fill Sylvia's bathtub with water = b minutes
Therefore,
Minutes taken to fill 3 bathtubs like Sylvia's bathtub = 3 × b minutes = 3b minutes
Hence, Minutes taken to fill 3 bathtubs like Sylvia's bathtub are 3b minutes.

Find a quadratic polynomial verifying f(-3) = – 18, f'(-3) = 16, f''(-3) = - 6.
Answers
Let f(x) = ax ² + bx + c. Then
f '(x) = 2ax + b
f ''(x) = 2a
f (-3) = -18, so
9a - 3b + c = -18
f ' (-3) = 16, so
-6a + b = 16
f '' (-3) = -6, so
2a = -6
Then a = -3, b = -2, and c = 3, so that
f(x) = -3x ² - 2x + 3

can someone give me the slope and y-intercept for this problem
Answers
Answer:
Slope: 2
Y-intercept: -4
Step-by-step explanation:
Slope = y2 - y1 / x2 - x1
Slope = -2 - -4 / 1 - 0
Slope = 2 / 1
Slope = 2
Y-intercept is when x = 0
This is shown on the first row
When x = 0, y = -4, which is our y-intercept

An Item is regularly priced at $60. It is now priced at a discount of 65% off the regular price. What is the price now?
Answers
Answer:
$21
Step-by-step explanation:
There are two ways to do this question:
1. Multiply 60 by .65 and minus the product from the original price ($60)
2. Multiply 60 by .35 (This is because the discounted price maintains 35% of the regular price)
Let's do it both ways:
1. (60)(.65) = 39
60 - 39 = 21
2. (60)(.35) = 21
Therefore, the price now is $21.
I hope this helps!!

Which statement is true if a is the fourth root of 16, Show your work
a x a x a x a = 16
a = 164
4a = 16
a = 16/4
Answers
Given:
The statement is " a is the fourth root of 16".
To find:
The true statement for the given statement.
Solution:
The given statement is
a is the fourth root of 16.
Mathematically, it can be written as
[tex]a=\sqrt[4]{16}[/tex]
Taking power 4 on both sides.
[tex]a^4=(\sqrt[4]{16})^4[/tex]
[tex]a\times a\times a\times a=16[/tex]
Therefore, the correct option is A.
A true statement , if a is the fourth root of 16 is
a x a x a x a = 16
Important Information :
'a' is the fourth root of 16'a' is the fourth root of 16 can be written as
[tex]a=\sqrt[4]{16}[/tex]
To remove fourth root, we take exponent 4 on both sides
[tex]a=\sqrt[4]{16}\\(a)^4=(\sqrt[4]{16})^4[/tex]
Exponent 4 and fourth root will get cancelled
[tex]a^4=16\\a \cdot a\cdot a \cdot a=16[/tex]
a x a x a x a = 16
A true statement , if a is the fourth root of 16 is
a x a x a x a = 16

Mario tiene un comercial tecnológico, vende una cámara web HD con una ganancia del 18% sobre el precio de costo. El compró la cámara en $15,00. ¿Cuál es el precio de venta de la cámara?
Answers
Answer:
El precio de venta de la cámara es de $17.70.
Step-by-step explanation:
Dado que Mario vende una cámara web HD con una tasa de ganancia del 18%, y compró dicho elemento a $15.00, para determinar el precio de venta del producto se debe realizar el siguiente cálculo:
15 + (15 x 18 / 100) = X
15 + (15 x 0.18) = X
15 + 2.70 = X
17.70 = X
Por lo tanto, el precio de venta de la cámara es de $17.70.
Ford and GM pick up trucks are being tested for fuel efficiency, which is commonly measured in miles per gallon (mpg). The fuel efficiency of Ford trucks is found to follow a normal distribution with mean 20 mpg and a standard deviation of 3 mpg. The fuel efficiency of GM trucks is found to follow a normal distribution with mean 24 mpg and standard deviation of 4 mpg. Compute the probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
Answers
Answer:
0.7881 = 78.81% probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Subtraction of normal variables:
When we subtract normal variables, the mean is the subtraction of the means, and the standard deviation is the square root of the sum of the variances.
The fuel efficiency of Ford trucks is found to follow a normal distribution with mean 20 mpg and a standard deviation of 3 mpg.
This means that [tex]\mu_{F} = 20, \sigma_{F} = 3[/tex]
The fuel efficiency of GM trucks is found to follow a normal distribution with mean 24 mpg and standard deviation of 4 mpg.
This means that [tex]\mu_{G} = 24, \sigma_{G} = 4[/tex]
Compute the probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
This is the probability that the subtraction of ford by gm is less than 0. First, we find the mean and the standard deviation.
[tex]\mu = \mu_{F} - \mu_{G} = 20 - 24 = -4[/tex]
[tex]\sigma = \sqrt{\sigma_{F}^2+\sigma_{G}^2} = \sqrt{3^2+4^2} = 5[/tex]
This probability is the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-4)}{5}[/tex]
[tex]Z = 0.8[/tex]
[tex]Z = 0.8[/tex] has a pvalue of 0.7881
0.7881 = 78.81% probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency

A napkin is folded into an isosceles triangle, triangle ABC, and placed on a plate, as shown. the napkin has a perimeter of 48 centimeters. trigonometric area formula: Area = 1/2abSin(c). To the nearest square centimeter, how many square centimeters of the plate are covered by the napkin? show your work for full credit.
Answers
Before finding the area of folded napkin, we should find the dimension of the napkin.
Find the length of the leg side, the two leg has similar length.
perimeter = 38
l + l + 8 = 38
2l + 8 = 38
2l = 30
l = 15
Each leg is 15 cm long.
Find the area of folded napkin
area = 1/2 × s × s × sin of angle between the sides
area = 1/2 × 15 × 15 × sin 30°
area = 1/2 × 15 × 15 × 1/2
area = 225/4
area = 56.25
to the nearest whole number >> 56 cm²
