Lincoln has p pennies and n nickles .he has at least $0 worth of coins altogether.write this situation as a inequality

skelet666 [1.2K]

Answer:

$p+n=0$

Step-by-step explanation:

Given that Lincoln has $p$ pennies and $n$ nickles and that his total worth is $0,

we can express his total using the inequality:

$p+n=0$

Where the sum of n and p is his total

Hence, Lincoln's situation is expressed as p+n=0

Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if BY = 3, YC = 2

Mazyrski [523]

Answer:

The ratio of the area of triangle XBY to the area of triangle ABC is $\frac{9}{25}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

In this problem

Triangles XBY and ABC are similar, because the corresponding internal angles are congruent

see the attached figure to better understand the problem

step 1

Find the scale factor

Let

z-------> the scale factor

$z=\frac{BY}{BC}$

we have

$BY=3\ units$

$BC=2+3=5\ units$

substitute

$z=\frac{3}{5}$

step 2

Find the ratio of the area of triangle XBY to the area of triangle ABC

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

we have

$z=\frac{3}{5}$ -----> scale factor

so

$z^{2} =(\frac{3}{5})^{2} =\frac{9}{25}$

Dy/dx = (cos x) e^(y+sinx) and y = 0 when x = 0. find the original equation

Korvikt [17]

Find the general solution by separating the variables then integrating:
dy / dx = cosx℮^(y + sinx)
dy / dx = cosx℮ʸ℮^(sinx)
℮^(-y) dy = cosx℮^(sinx) dx
∫ ℮^(-y) dy = ∫ cosx℮^(sinx) dx
-℮^(-y) = ℮^(sinx) + C
℮^(-y) = C - ℮^(sinx)
-y = ln[C - ℮^(sinx)]
y = -ln[C - ℮^(sinx)]

Find the particular solution by solving for the constant:
When x = 0, y = 0
-ln(C - 1) = 0
ln(C - 1) = 0
C - 1 = 1
C = 2
<span>y = -ln[2 - ℮^(sinx)]

Kisachek [45]

Answer:

D. 4, B. 4, C. 8

Step-by-step explanation:

The data are centered around 4; the plot is pretty evenly spread out around the center, 4 miles. (The actual average is 3.88.)

The most number of miles run (look for tallest column of dots) is 4.

The number of people who ran is 8 (count the dots above the 5-mile label).
