Answer:

7 = x^1/2.

Step-by-step explanation:

logx 7 = 1/2

Converting to exponential form ( the value of the log is the exponent and x is the base):

7 = x^1/2

A boundary stripe 6 in. wide is painted around a rectangle whose dimensions are 120 ft by 230 ft. Use differentials to approxima

Nimfa-mama [501]

Answer:

350 square feet

Step-by-step explanation:

We are given that

Width of strip=6 in

Dimension of rectangle= $20 ft\times 230 ft$

We know that

Area of rectangle ,A=xy

Differentiate

$dA=\frac{\partial A}{\partial x}x+\frac{\partial A}{\partial y}y$

We have $\frac{\partial A}{\partial x}=y=230 ft$

$\frac{\partial A}{\partial y}=x=120$

$dx=\frac{12}{12}=1 ft$

1 ft=12 in

Because 6 in added in both side of breadth

dy= $\frac{12}{12}=1 ft$

Because 6 in added on both sides of length of rectangle

Substitute the values

$dA=230\times 1+120\times 1=350 ft^2$

Hence, the number of square feet of paint in the strip=350 square feet

Which ordered pair is a solution to the system of inequalities ? (1, –5) (3, 0) (–1, –2) (1, 5)

Musya8 [376]

Point (3,0) is system solution.

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

We have

y> -2

x + y <4

For (1,-5):

First inequation:

-5> -2 (incorrect)

Second inequality:

1-5 <4 (correct)

For (3,0):

First inequation:

0> -2 (correct)

Second inequality:

0+3 <4 (correct)

For (-1,-2):

First inequation:

-2> -2 (incorrect)

Second inequality:

-1-2 <4 (correct)

For (1,5):

First inequation:

5> -2 (correct)

Second inequality:

1+5 <4 (incorrect)

Hence, Point (3,0) is system solution.

F(x) = -4x + 15 g(x) = 7x^3 Find (f-g)(2)

djyliett [7]

$(f-g)(2)=f(2)-g(2)$

Therefore, find f(2) and g(2) first before subtracting.

$f(x)=-4x+15$

Therefore,

$f(2)=-4(2)+15\\f(2)=-8+15\\f(2)=7$

Then find g(2)

$g(x)=7x^3\\g(2)=7(2)^3\\g(2)=7(8)\\g(2)=56$

Then put f(2) to subtract g(2)

$f(2)-g(2)=7-56\\f(2)-g(2)=-49$

Therefore, the answer is (f-g)(2) = -49.
