70 + x + 55 + 30 = 180

7 Days It will take a week aka 7 days

Answer:

x = 3

y = 17  

or (3,17)

Step-by-step explanation:

y = 4x + 5

y = -1/3x - 8

4x + 5 = -1/3x - 8

4x = -1/3x - 13

12x = -x - 39

13x = -39

x = 3

y = 4(3) + 5

y = 12 + 5

y = 17

Answer:

Step-by-step explanation:

Letter B is the correct answer

Initial population is 200, tripled every hour

200 x 3 = 600

First hour 200

Second hour = 600 + 200 = 800

Third hour 800x3 = 2400 + 800 = 3200

and so on.

Enter the equation in standard form.

y –4=-(x + 3)

we know that

The equation of the line in standard form is equal to

Ax+By=C

where

A is a ositive integer

B and C are integers

so

we have

y-4=-(x+3)

REmove the parenthesis right side

y-4=-x-3

Group terms

x+y=4-3

x+y=1

therefore

the answer is

x+y=1

Answer:

Below

Step-by-step explanation:

First find the area of the triangle

A = bh/2

   = (5)(10)/2

   = 50/2

   = 25 in^2

*the height of the triangle is 10 because we are disregarding the 3 inches as it is not a part of the triangle

You can now find the volume of the triangular part

V = area x height

   = (25)(10)

   = 250 in^3

Now find the volume of the rectangular part

V = LWH

   = (10)(5)(3)

   = 150 in^3

Add these two up to get the total volume

150+250 =400 in^3

I hope that is correct.... good luck!

Answer:

y= 5/6x+4

Step-by-step explanation:

you go up 5

over 6

so 5/6

then its already on positive 4 so its +4

Slope-intercept form is the form of a line where y equals the product of the slope and the input plus the y-intercept, or:

y = mx + b

\(m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{9 - 4}{6-0}\\m = \frac{5}{6}\)

b = 4

The final equation of the line is:

y = 5/6x + 4

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

y = (2)³ - 4(2) + 6 = 6: (2, 0)

The equations at these points are

y = 8x + 16

y = 8x - 16

1. The quadratic function for the Area in terms of x: A(x) = 24x.

2. The cross-sectional area is maximized when the depth of the gutter is 0.

3. The maximum cross-sectional area is square inches 0.

To determine the depth of the gutter that maximizes its cross-sectional area and allows the greatest amount of water to flow, we need to follow a step-by-step process.

1. Write a quadratic function for the area in terms of x:

The cross-sectional area of the gutter can be represented as a rectangle with a width of 24 inches and a depth of x. Therefore, the area, A(x), is given by A(x) = 24x.

2. The cross-sectional area is maximized when the depth of the gutter is:

To find the value of x that maximizes the area, we need to find the vertex of the quadratic function. The vertex of a quadratic function in form f(x) = ax² + bx + c is given by x = -b/(2a). In our case, a = 0 (since there is no x² term), b = 24, and c = 0. Thus, the depth of the gutter that maximizes the area is x = -24/(2 * 0) = 0.

3. The maximum cross-sectional area is square inches:

Substituting the value of x = 0 into the quadratic function A(x) = 24x, we get A(0) = 24 * 0 = 0. Therefore, the maximum cross-sectional area is 0 square inches.

No, Raul is not correct, he will run 0.233333 miles each day which is much less than what he needs to run each day

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Raul wants to run 30 miles this week

He wants to run the same number of miles each day

He says he will run 7/30 miles each day

Does he correct = ?

If he wants to run 30 miles this week and wants to run the same number of miles each day,

then he needs to run

= 30 miles / 7 days

= 4.285714 miles each day.

Running 7/30 miles each day would mean that he runs,

7 miles / 30 days

= 0.233333 miles each day,

which is much less than what he needs to run each day in order to achieve his goal of 30 miles for the week.

The counter example of the statement is an image of parallel lines l and m

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the two lines be represented as line l and m

Now , if two intersecting lines form two pairs of vertical angles, one pair of angles will be acute, and one pair of angles will be obtuse

So , the angles can be either right angles

When lines intersect, two angle relationships are formed:
