Answer:

5539 or 1764[tex]\pi[/tex]

Step-by-step explanation:

to find the area, we need the radius

The radius(R) is half of the diameter(D)

R = D/2

R = 42/2

R = 21

area of a circle(A) = pi x radius[tex]^{2}[/tex]

A = pi( which most times in a problem, equals 3.14) x 42[tex]^{2}[/tex]

A = 3.14 x 1764

A = 5538.96

A(when rounded) = 5539

Answer: 5.25

Step-by-step explanation:

Solve using PEMDAS,

(8)2 - (43) ÷ 4

16 - 10.75 = 5.25

Answer:

A

Step-by-step explanation:

A solution exists for constructing a triangle given two sides and the included angle if the triangle inequality theorem is satisfied

We have to draw a line segment to represent one of the given sides of the triangle.

From one endpoint of the line segment, use a protractor to measure the given angle. Mark this angle on the line segment.

Using a compass, set the compass to the length of the other given side of the triangle.

With the compass centered at the endpoint of the line segment, draw an arc that intersects the angle on the line segment.

Draw a line connecting the endpoint of the line segment to the point where the arc intersects the angle.

This line represents the second side of the triangle.

Finally, draw a line connecting the two endpoints of the sides you have constructed. This line completes the triangle.

The required negative function h(x) with a y-intercept at "-4" with one solution is x + 4

The y-intercept of an equation is the pint where the x-value of the function is 0, that is;

f(-4) = 0

Since the solution has one solution, hence it will be linear in nature

h(x) = x + 4

This gives the required negative function h(x) with a y-intercept at "-4" with one solution

Answer:(1, 5)

Step-by-step explanation:

The predicted height is close to the actual height of the plant by 0.69 cm

The equation of the height function of the plant is given as:

y = 1.44x + 1.55

The height on day 7 is calculated as:

y = 1.44 * 7 + 1.55

Evaluate

y = 11.63

The recorded height is given as 12.32

The residual is calculated as:

Residual = Recorded - Predicted

So, we have:

Residual = 12.32 - 11.63

Evaluate

Residual = 0.69

Hence, the predicted height is close to the actual height of the plant by 0.69 cm

The number of miles she drove the van for is 250 miles

From the question, we are to determine the number of miles Shelly drove the van

The given equation which shows the relationship between the number of days she rented the van, d, and the number of miles she drove the van, m is

20d + 0.7m = 235

Now, if she rented the van for 3 days, that is, d = 3

Putting the value of d = 3 into the equation to determine the value of m

We get

20(3) + 0.7m = 235

60 + 0.7m = 235

0.7m = 235 - 60

0.7m = 175

m = 175 / 0.7

m = 250

Hence, the number of miles she drove the van for is 250 miles

Answer:

Answer = 6^7

Step-by-step explanation:

When multiplying expressions with exponent you add the exponents together. So here you would get 6^13/6^6. However you can simplify this farther since the base (6) is the same. When dividing expressions with exponents you subtract the exponents so the the answer would be 6^7.

Answer:

2/7

Step-by-step explanation:

there's seven parts in green (2 yellow and 5 blue)

two of them are yellow

so 2/7 is the fraction

(seven is prime so it's already in simplest form.)

Answer:

A=0

B=2

so we have our question, h (x) x^3, x<0.

a is equal to 0 since that answer was already given.

so now it would be srqt/x over 0 of 4

4 divided by 0 is 0

1/2x x>4

turns into 1/2x x>4/1

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{1}{3}}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{-1}{3}} ~\hfill \stackrel{reciprocal}{\cfrac{3}{-1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{-1}\implies 3}}[/tex]

so we're really looking for the equation of a line whose slope is 3 and passes through (1 , 10)

Answer:

17

Step-by-step explanation:

→ f(x) = 3x + 2

→ f(5) = 3(5) + 2

→ 15 + 2

→ 17 is the answer.

Answer:

F(5) = 17

Step-by-step explanation:

to solve, we just need to plug all values of x into 5 as shown

f(x) = 3x + 2
f(5) = (3*5) + 2

then following the format of PEMDAS (explained at footer) we solve the new equation

f(5) = (3*5) + 2
f(5) = 15 + 2
f(5) = 17

therefor F(5) is equal to 17

The PEMDAS format of solving equations:

the term Pemdas stands for the steps involved in solving an equation
Parenthasis (follow PEMDAS within these ( ) first untill in simplest form)
Exponents (such as x^y)
Multiply (any multiplication)
Devide (any devision)
Addition (any addition)
Subtraction (any subtraction)
