if the point (-4,5) and (0,2) are used to find the slope of the line the slope is -3/4 what is the slope if the points (0,2) and (4,-1) are used

Answer:

(f+g)(1)

equals

3

Step-by-step explanation:

(f+g)(1) is f(1)+g(1).

f(1) means what y corresponds to x=1 so f(1)=-1.

g(1) means what y corresponds to x=1 so g(1)=4.

So (f+g)(1)=f(1)+g(1)=-1+4=3.

Answer:

5(5 + 2).

Step-by-step explanation:

5 is a factor of 25 and 10 so :

15 + 10 = 5(5 + 2).

For this case we have that by definition, the distributive property establishes:

[tex]a (b + c) = ab + ac[/tex]

Then, using the above definition, we must write an expression equivalent to:

[tex]25 + 10[/tex]:

The largest integer that divides both numbers without leaving residue is 5, then:

[tex]5 (5 + 2) = 5 * 5 + 5 * 2 = 25 + 10[/tex]

Answer:

192 pieces of tiles will be required.

Step-by-step explanation:

A customer is tiling a shower's back wall which is in the dimensions of 6' by 4'

This area of the wall is = 6 × 4 square feet = 24 feet²

Customer wants to cover this wall with the tiles measuring 3" by 6" or 3 inches by 6 inches.

Now we will convert these dimensions of the tiles in foot.

Since 12 inches = 1 foot

Therefore, 1 inch = [tex]\frac{1}{12}[/tex] foot

Dimensions of one tile in foot will be [tex]\frac{3}{12}[/tex] foot by [tex]\frac{6}{12}[/tex] foot.

In simplified form, dimensions of the tile is [tex]\frac{1}{4}[/tex] foot by [tex]\frac{1}{2}[/tex] foot.

Area of one tile = [tex]\frac{1}{4}\times \frac{1}{2}=\frac{1}{8}[/tex] square feet

Number of tiles = [tex]\frac{\text{Area of the wall}}{\text{Area of one tile}}[/tex]

                          = [tex]\frac{24}{\frac{1}{8}}[/tex]

                          = 24×8

                          = 192 tiles

Therefore, 192 pieces of tiles will be required.

Hence the angle of the painting with the mirror =58 degree.

Answer:

f(3) = 1

Step-by-step explanation:

f(x) = x² - 2ˣ

You are solving for f(3). Plug in 3 for x in the equation:

f(3) = (3)² - (2)³

Simplify. First, simplify each number by solving the powers, then subtract:

f(3) = (3 * 3) - (2 * 2 * 2)

f(3) = (9) - (8)

f(3) = 9 - 8

f(3) = 1

f(3) = 1 is your answer.

Answer:

Summation notation:

[tex]\frac{1}{2}\sum_{k=1}^6f((.5k))[/tex]

or after using your function part:

[tex]\frac{1}{2}\sum_{k=1}^6(-(.5k)^2+2(.5k)+4)[/tex]

After evaluating you get 11.125 square units.

Step-by-step explanation:

The width of each rectangle is the same so we want to take the distance from x=0 to x=3 and divide by 6 since we want 6 equal base lengths for our rectangles.

The distance between x=0 and x=3 is (3-0)=3.

We want to divide that length of 3 units by 6 which gives a length of a half per each base length.

We are doing right endpoint value so I'm going to stat at x=3. The first rectangle will be drawn to the height of f(3).

The next right endpoint is x=3-1/2=5/2=2.5, and the second rectangle will have a height of f(2.5).

The next will be at x=2.5-.5=2, and the third rectangle will have  a height of f(2).

The fourth rectangle will have a height of f(2-.5)=f(1.5).

The fifth one will have a height of f(1.5-.5)=f(1).

The last one because it is the sixth one will have a height of f(1-.5)=f(.5).

So to find the area of a rectangle you do base*time.

So we just need to evaluate:

[tex]\frac{1}{2}f(3)+\frac{1}{2}f(2.5)+\frac{1}{2}f(2)+\frac{1}{2}f(1.5)+\frac{1}{2}f(1)+\frac{1}{2}f(.5)[/tex]

or by factoring out the 1/2 part:

[tex]\frac{1}{2}(f(3)+f(2.5)+f(2)+f(1.5)+f(1)+f(.5))[/tex]

To find f(3) replace x in -x^2+2x+4 with 3:

-3^2+2(3)+4

-9+6+4

1

To find f(2.5) replace x in -x^2+2x+4 with 2.5:

-2.5^2+2(2.5)+4

-6.25+5+4

2.75

To find f(2) replace x in -x^2+2x+4 with 2:

-2^2+2(2)+4

-4+4+4

4

To find (1.5) replace x in -x^2+2x+4 with 1.5:

-1.5^2+2(1.5)+4

-2.25+3+4

4.75

To find f(1) replace x in -x^2+2x+4 with 1:

-1^2+2(1)+4

-1+2+4

5

To find f(.5) replace x in -x^2+2x+4 with .5:

-.5^2+2(.5)+4

-.25+1+4

4.75

Now let's add those heights.  After we obtain this sum we multiply by 1/2 and we have our approximate area:

[tex]\frac{1}{2}(f(3)+f(2.5)+f(2)+f(1.5)+f(1)+f(.5))[/tex]

[tex]\frac{1}{2}(1+2.75+4+4.75+5+4.75)[/tex]

[tex]\frac{1}{2}(22.25)[/tex]

[tex]11.125[/tex]

Okay now if you wanted the summation notation for:

[tex]\frac{1}{2}(f(3)+f(2.5)+f(2)+f(1.5)+f(1)+f(.5))[/tex]

is it

[tex]\frac{1}{2}\sum_{k=1}^{6}(f(.5+.5(k-1)))[/tex]

or after simplifying a bit:

[tex]\frac{1}{2}\sum_{k=1}^6 f((.5+.5k-.5))[/tex]

[tex]\frac{1}{2}\sum_{k=1}^6f((.5k))[/tex]

If you are wondering how I obtain the .5+.5(k-1):

I realize that 3,2.5,2,1.5,1,.5 is an arithmetic sequence with first term .5 if you the sequence from right to left (instead of left to right) and it is going up by .5 (reading from right to left.)

Step-by-step explanation:

Point slope form: Y-y1=m(x-x1)

Answer:

Step-by-step explanation:

Point-slope form of a line is [tex]y-y_1=m(x-x_1)[/tex] where the slope is [tex]m[/tex] and [tex](x_1,y_1)[/tex] is a point on the line.

We know both of those things so we have enough information without doing any math to do this problem.  You just got to plug in.

So replace [tex]m[/tex] with -2, [tex]x_1[/tex] with 4, and [tex]y_1[/tex] with -6.

Answer:

  x-axis

Step-by-step explanation:

A line with a slope of zero has the same y-value everywhere, so is parallel to the line y=0, the x-axis.

Answer:

x- axis

Step-by-step explanation:

We  are given that any line whose slope is zero.

We have to find the line with a slope  of zero is parallel to which axis.

We know that when any line is parallel to x- axis

It means y does not change with

Therefore, [tex]\frac{dy}{dx}=0[/tex]

Slope of a line which is parallel to x- axis is zero because y does not vary with x.

But when a line parallel to y - axis then slope of that line is undefined.

When line y=x

Then , [tex]\frac{dy}{dx}=1\neq 0[/tex]

Hence, any line with slope of zero is parallel to the x- axis.

Answer:x- axis.

Answer:

D. 3

Step-by-step explanation:

In the Point-Slope Formula, y - y₁ = m(x - x₁), m represents the rate of change [slope], which in this case is 3.

I am joyous to assist you anytime.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The slope of the line y + 1 = 3 (x - 4) is 3.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line y + 1 = 3 (x - 4)

y + 1 = 3 (x - 4)

Subtract 1 on both sides.

y = 3(x - 4) - 1

y = 3x - 12 -1

y = 3x - 13

This is in the form of y = mx + c

Now,

Slope = m

m = 3

Thus,

The slope of the line y + 1 = 3 (x - 4) is 3.

Answer:

360 miles

Step-by-step explanation:

If you travel 90 miles in 1 ½ hours, it will take 360 miles if you drove 6 hours.

All you have to do is, multiply 1 ½  until you get to 6.

The easiest way is:

1 ½ = 90 miles

1 ½ (90 miles) x 2 = 3 or 180 miles

3 (180 miles) x 2 = 6 or 360

Therefore, 6 hours = 360 miles.

Final answer:

This detailed answer explains how to calculate distances based on speed and time using a specific formula.

Explanation:

The question is about calculating distances traveled based on time and speed.

To find the distance, use the formula: distance = speed × time.

Given 90 miles in 1 ½ hours, first find the speed: 90 miles ÷ 1.5 hours = 60 miles/hour.

Then for 6 hours of travel: distance = 60 miles/hour × 6 hours = 360 miles.

Answer: c) 24.9

Step-by-step explanation:

Use the distance formula then add and round to nearest tenth

The perimeter of the triangle ABC will be 24.9. Then the correct option is C.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x – h)² + (y – k)²

The vertices of the triangle are A(1, 3), B(11, 4), and C(7, 9).

The distance between AB will be

AB² = (11 – 1)² + (4 – 3)²

AB² = 101

AB = 10.05

The distance between BC will be

BC² = (11 – 7)² + (4 – 9)²

BC² = 41

BC = 6.40

The distance between AC will be

AC² = (7 – 1)² + (9 – 3)²

AC² = 72

AC = 8.50

Then the perimeter of the triangle ABC will be

Perimeter = AB + BC + CA

Perimeter = 10.05 + 6.40 + 8.50

Perimeter = 24.95 ≈ 24.9

The perimeter of the triangle ABC will be 24.9.

Step-by-step explanation:

The slope - intercept equation is

[tex]y = mx + b[/tex]

where m = slope

and b = intercept

The line intercepts the y axis in -9/2, so b = -9/2

To calculate the slope we can take two points where the line passes:

Answer:

14-inch pizza

Step-by-step explanation:

The area of a circle (or a pizza) is πr^2, if r is the radius.

For a 14-inch pizza, the radius is 14/2=7 and therefore the area is π*7^2 which is approximately 154 square inches. Therefore, the price per square inch is 12/154, or approximately 0.078 dollars per inch.

Similarly, the area of a 4-inch pizza is π*2^2 which is approximately 12.5 square inches, two 4-inch pizzas are 25, and so the price per square inch is 8/25 which is approximately 0.32 dollars per inch.

So the 14-inch pizza is the better deal.

1 meter = 100 cm

6.5 meters = 6.5 * 100 = 6500 cm

1 km = 1000 meters.

5 km = 5 * 1000 meters = 5000 meters.

Answer:

A, B, E, F

Step-by-step explanation:

In a 30-60-90 triangle, the hypotenuse is twice the length of the short leg.

That makes choice E possible.

In a 30-60-90 triangle, the long leg is sqrt(3) times the length of the short leg.

That makes choices A, B, and F possible.

Answer:

First option.

Option 5.

Option 6.

Step-by-step explanation:

The formula for a 30-60-90 triangle is this:

1) Side opposite to 30 will be value [tex]a[/tex].

2) Side opposite to 60 will be value [tex]a\sqrt{3}[/tex].

3) Hypotenuse will be [tex]2a[/tex].

So let's look and see:

First option: [tex]AB=4[/tex] and [tex]BC=4\sqrt{3}[/tex]

AB is opposite of the angle with 30 degree measurement.

BC is opposite of the angle with 60 degree measurement.

So [tex]a=4[/tex] here.

So the side opposite of 60 using the formula should be [tex]4 \sqrt{3}[/tex] which it is here.

So first option looks good.

Second option: [tex]BC=2\sqrt{3}[/tex] and [tex]AC=2[/tex].

We aren't given the side opposite to 30.

AC is the hypotenuse so 2a=2 which means the side opposite to 30 is a=2/2=1.

This means using the formula that the side opposite to 60 will be [tex]1\sqrt{3}=\sqrt{3}[/tex] but we don't have that.

So not option 2.

Third option: [tex]AB=3[/tex] and [tex]AC=3\sqrt{3}[/tex]

AB is the side opposite of 30, so we have [tex]a=3[/tex]

AC is the hypotenuse so that side should be [tex]2a=6[/tex] and it isn't.

Option 3 is not working.

Fourth option: [tex]BC=10[/tex] and [tex]AC=4\sqrt{3}[/tex]

So we have that [tex]2a=4\sqrt{3}[/tex] which means [tex]a=2\sqrt{3}[/tex] and so [tex]a\sqrt{3}=2\sqrt{3}\sqrt{3}=2(3)=6[/tex] but that is a contradiction because we have this value should be 10.

Not option 4.

Option 5: [tex]AB=7[/tex] and [tex]AC=14[/tex]

So we have [tex]a=7[/tex] and [tex]2a=14[/tex] so this looks good.

Option 6: [tex]AB=11[/tex] and [tex]BC=11\sqrt{3}[/tex]

[tex]a=11[/tex] so [tex]a\sqrt{3}=11\sqrt{3}[/tex] which is what we have.

Option 6 works.

Answer:

The domain is {1,2,3,4,5}

The range is {150,135,120,105,90}

Step-by-step explanation:

Domain is the set of x-values (x axis) and Range is the set of y-values (y axis).

Now if you look at the relation (points given), you can see the 5 points corresponds to 1,2,3,4, adn 5 in the x axis (minutes). So this is the domain - 1,2,3,4,5.

If we look at the y-axis (Heart Rate) , the values corresponding to 1,2,3,4,and 5 are 150, 135, 120, 105, and 90. These are the range.

Hence the last choice is the correct answer.

Answer: Domain = {1,2,3,4,5}

Range = {150,135, 120,105, 90}

Step-by-step explanation:

We know that,

Domain : Set of all input values .

Range : Set of output values.

In a graph, x values are the input values and y values are output values.

Given : The graph shows Melissa's heart rate in beats per minute be) during the first few minutes other cool down after  jogging .

In the graph, number of minutes are shown by x-values and heart rate are shown by y-values.

Thus from graph, Domain = {1,2,3,4,5}

Range = {150,135, 120,105, 90}

Answer:

the area of a sector is 151.976 cm²....

Step-by-step explanation:

Area of sector(A)is given by:

A=πr².θ/360°

where,

r is the radius and θ is the angle in degree.

As per the statement:

A central angle of 4π/5 radians and a radius of 11 cm.

r=11cm

Use conversion:

1 radian=180/π

then:

4π/5 radians=180/π * 4π/5

=144°

θ=144°

Substitute these given values and use 3.14 for π we have;

A=3.14*(11)²*144/360

A=3.14(121)*144/360

A=379.94*0.4

A=151.976 cm²

Therefore the area of a sector is 151.976 cm²....

The area of a sector with a central angle of 4π/5 radians and a radius of 11 cm is approximately 96.8 cm², calculated using the formula A = (θ/2π) * πr² and rounded to two significant figures.

To find the area of a sector of a circle with a given central angle in radians and a specific radius, you can use the formula:

A = (θ/2π) * πr²

where A is the area of the sector, θ is the central angle in radians, and r is the radius of the circle.

In this case, the central angle is 4π/5 radians and the radius is 11 cm. Substituting the given values into the formula:

A = (4π/5/2π) * π * (11 cm)²
= (2/5) * π * 121 cm²
= (2/5) * 3.1415927 * 121 cm²
= 96.76 cm² to two significant figures, since the radius is given to two significant figures.

Hence, the area of the sector is approximately 96.8 cm².

Answer: x = 24

Step-by-step explanation:

3/4 (x/4 + 8) - x/2 +2 = 3/8 (4-x) - x/4

3x/16 + 6 - x = 3/2 - 3x/8 - x/4

collect like term

3x/16 - x+ 3x/8 +x/4 = 3/2 -6

3x-16x+6x +4x / 16 = 3-12 / 2

-3x/16 = -9/2

cross multiply

-6x = -144

Divide bothside by -6

-6x/-6 = -144/6

x = 24

Sure, let's solve the equation:
\[ \frac{3}{4}\left(\frac{1}{4}x + 8\right) - \left(\frac{1}{2}x + 2\right) = \frac{3}{8}(4 - x) - \frac{1}{4}x \]
First, distribute the fractions across the terms inside the parentheses:
\[ \frac{3}{4} \cdot \frac{1}{4}x + \frac{3}{4} \cdot 8 - \frac{1}{2}x - 2 = \frac{3}{8} \cdot 4 - \frac{3}{8} \cdot x - \frac{1}{4}x \]
[Simplify the terms]:
\[ \frac{3}{16}x + 6 - \frac{1}{2}x - 2 = \frac{3}{2} - \left(\frac{3}{8} + \frac{1}{4}\right)x \]
Now, combine like terms:
\[ \frac{3}{16}x - \frac{8}{16}x + 4 = \frac{3}{2} - \frac{3}{8}x - \frac{2}{8}x \]
\[ -\frac{5}{16}x + 4 = \frac{3}{2} - \frac{5}{8}x \]
Next, we want to solve for \( x \), so we'll move all the \( x \)-terms to one side and the constants to the other side:
\[ -\frac{5}{16}x + \frac{5}{8}x = \frac{3}{2} - 4 \]
Convert \( \frac{5}{8} \) to a fraction with a denominator of 16:
\[ -\frac{5}{16}x + \frac{10}{16}x = \frac{6}{4} - \frac{16}{4} \]
Combine like terms again:
\[ \frac{5}{16}x  = -\frac{10}{4} \]
\[ \frac{5}{16}x = -2.5 \]
Finally, solve for \( x \):
\[ x = \frac{-2.5}{\frac{5}{16}} \]
\[ x = -2.5 \cdot \frac{16}{5} \]
\[ x = -2.5 \cdot 3.2 \]
\[ x = -8 \]
So the solution for \( x \) in the given equation is \( x = -8 \).

Answer:5 vans   7 cars

Step-by-step explanation:

c=cars         v=vans

c+v= 12

c =( 12-v)

11v + 4(12-v) = 83

11v + 48-4v = 83

7v = 35

v= 5

c = 12-5         c = 7

7 cars x 4 students = 28 students

5 vans x 11 students = 55 students

55+28 = 83 students

Answer:

5'4"

Step-by-step explanation:

In terms of height, the apostrophe ( ' ) stands for feet and the quotation mark ( " ) stands for inches.

Your first term includes 4 feet and 9 inches. There are 12 inches in a foot, so we can simplify this as being 57 (48+9) inches.

Your second term includes 7 inches.

Add your two terms (57 and 7) together, and you have 64 inches.

Again, there are 12 inches in a foot, so to convert 64 inches to feet, count how many times you can put 12 into 64 without surpassing 64.

12 / 24 / 36 / 48 / 60

This will result in 5 times, so you have 5 feet and 4 inches left over.
