Answer:

1.7$

Step-by-step explanation:

Given

original price = $2.87

New price = $2.82

Percentage decrease = original price-New price/New price × 100

Percentage decrease = 2.87-2.82/2.87× 100

Percentage decrease = 0.05/2.87 × 100

Percentage decrease = 5/2.87

Percentage decrease = 1.7%

Please help answer choices are: A. 46° B. 67° C. 115° D. 134°

Answer:

134°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠XCA = ∠XAC . Congruent angles

∠XAC = 1/2(46) = 23° . because CE bisects ∠ C

∠XCA = 23°

180° - 23° - 23° = 134° . Sum of all angles in a triangle is 180°

What transformations change the graph of f(x) to the graph of g(x)?

Dennis_Churaev [7]

For this case we have that the main function is given by:

$f (x) = - 7x ^ 2$

We apply the following transformations:

Vertical expansions:

To graph y = a * f (x)

If a> 1, the graph of y = f (x) is expanded vertically by a factor a.

For a = 5 we have:

$h (x) = 5 * f (x)\\h (x) = 5 * (- 7x ^ 2)\\h (x) = - 35x ^ 2$

Vertical translations:

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

For k = 5 we have:

$g (x) = h (x) + k\\g (x) = - 35x ^ 2 + 5$

Answer:

The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.

A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f

kvasek [131]

Answer:

$\frac{dr}{dt}=0.11062ft/sec$

Step-by-step explanation:

From the question we are told that:

Radius $r=5ft$

Height $H=15ft$

Rate $R=15ft/3sec =5ft/s$

Surface Radius $R_{surf}=2.2ft$

Generally the equation for Volume is mathematically given by

$V=\frac{1}{3}\pi*r^2h$

Since radius to height ratio gives

$\frac{r}{h}=\frac{5}{15}$

$\frac{r}{h}=\frac{1}{3}$

$h=3r$

Therefore

$V=\frac{1}{3}\pi*r^2(3r)$

$V=\pi r^3$

Generally the equation for Change of Volume is mathematically given by

$\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)$

$\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}$

$\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{5}{45.62}$

$\frac{dr}{dt}=0.11062ft/sec$
