Answer:

a) 1.24 g/ml

b) 2.4%

Step-by-step explanation:

density = mass/volume

volume of sample = 28.4 - 15 = 13.4mL

density = 13.4/10.8

=1.24 g/ml

percent error

1.27 - 1.24 = 0.03

0.03/1.24 *100% = 2.4% error

Carlos Martin received a statement from his bank showing a balance of $56.75 as of March 15th his check book shows a balance of $87.37 as of March 20th. the bank returned all the cancelled checks but too. One check was for $5 and the other was for $13.25 how much did Carlos deposit in his account between the March 15th and the March 20th.A. $125.87
B. $11.22
C. $162.37
D. $48.87

Answers

Answer:

$48.87

Step-by-step explanation:

Let the deposited amount between the March 15th and the March 20th be x

Balance on 15th march = $56.75

The bank returned all the cancelled checks but too. One check was for $5 and the other was for $13.25

And he also deposited x amount

After deposits and deductions

So, balance = 56.75 +x - (13.25+5)

The new balance on 20th march = $87.37

⇒ $56.75 +x - (13.25+5)=87.37$

⇒ $56.75 +x - 18.25=87.37$

⇒ $38.5 +x =87.37$

⇒ $x =87.37-38.5$

⇒ $x =48.87$

Hence Carlos deposited $48.87 in his account between the March 15th and the March 20th.

March 15 balance: 56.75
Add: Deposit x
Less: Outstanding check 18.25 ⇒ 5 + 13.25
March 20 balance: 87.37

56.75 + x - 18.25 = 87.37
x = 87.37 - 56.75 + 18.25
x = 48.87 CHOICE D.

Outstanding checks are issued checks that are not yet deducted from the account.

A curve is described by the following parametric equations:x = 2 - t
y = x^2 + 1
Which statement best describes the curve?

The curve is a parabola with a vertex at (2, 1) and is traced from left to right for increasing values of t.
The curve is a parabola with a vertex at (2, 1) and is traced from right to left for increasing values of t.
The curve is a parabola with a vertex at (-2, -1) and is traced from left to right for increasing values of t.
The curve is a parabola with a vertex at (-2, -1) and is traced from right to left for increasing values of t.

Answers

When you use a parameter to describe equations then you are talking about Parametric Equations, that is, you can write both $x$ and $y$ as functions of a parameter $t$ . In this problem we have the following equations:

$x=2-t \n y=x^(2)+1$

So substituting $x$ in $y$ we have:

$y=(2-t)^2+1 \n y=4-4t+t^2+1 \n y=t^2-4t+5$

So this equation represents a parabola where $y$ is the dependent variable and $t$ is the independent variable. This equation is shown in the figure below, the best statement that describes this curve is:

The curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t.

A curve is described by parametric equations x = 2 - t;

y = x^2 + 1 statement the curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t is the best-described curve.

We use a parameter to describe equations then we are talking about Parametric Equations, that isWe can write both as functions of a parameter.

We have given the parametric equation

$x = 2 - t\ny = x^2 + 1$

What is the parametric equation?

The parametric equation defines a group of quantities as functions of one or more independent variables called parameters.

So substituting the value of x in y we get,

$y=(2-t)^2+1\ny=2^2-4t+t^2+1\ny=4-4t+t^2+1\ny=5-4t+t^2\n$

So this equation represents a parabola where y is the dependent variable and t is the independent variable.

This equation is shown in the following figure, the best statement that describes the curve.

Therefore we can say that the curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t.
