The price of a gallon of gasoline dropped by $0.08 on Wednesday and by 0.25 of that amount on Thursday. Which best represents how the price of a gallon of gasoline changed on Thursday? –0.32 –0.02 0.02 0.32

Answer:

Less Than

Step-by-step explanation:

 Given;

The equation of one exponential function is

[tex]g(x)=-9(0.1)^x[/tex]

Solve for (y-intercept of g(x))

⇒ [tex]g(x) = -9(0.1)^x[/tex]

⇒ [tex]y = -9(0.1)^0[/tex]

⇒ [tex]y = -9[/tex]

Note;

The y-intercept is when x = 0

y-intercept of h(x) = 6

Hence, knowing that  -9 < 6.

Thus, y-intercept of g(x) is less than the y-intercept of h(x).

Answer:

less than

Step-by-step explanation:

The y-intercept is when x = 0

Function g(x)

[tex]g(x)=-9(0.1)^x[/tex]

Input x = 0 into the equation and solve:

[tex]\implies g(0)=-9(0.1)^0=-9[/tex]

Therefore, the y-intercept of g(x) is (0, -9)

Function h(x)

From inspection of the table, the y-intercept of h(x) is (0, 6)

As -9 < 6, the y-coordinate of the y-intercept of g(x) is less than the y-coordinate of the y-intercept of h(x)

Answer:

2:1

Step-by-step explanation:

use k:1 as ratio, and then apply the section formula.

let's use the x co-ordinate pf the point in between the other two which is=(3)

section formula says,

x=mx2 + nx1/(m+n)

m=k , n=1

substitute all the values,

3=5k+(-1)/(k+1)

take k+1 to left side,

3(k+1)=5k-1

3k+3=5k-1

5k-3k=3+1

2k=4

(÷2)

k=2

hence, the ratio = 2:1

Answer:Top Left

Step-by-step explanation:

Graph A represents the given inequality 3y−5x>−6. Option A is correct.

From the graphs, the graph is to choose which best describes the inequality 3y−5x>−6

Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Given inequality,

3y−5x>−6.

Since the inequality contains only greater than sign, so options B and C will be omitted because both the graphs show boundary conditions that are wrong for the given inequality.
Now, graph A and D show now boundary condition and shaded portions

3y−5x>−6

Since the inequality is shown greater than -6 so the inequality will start from a negative y toward the positive y i.e.

3y−5x > −6

3y > 5x - 6
y > (5x - 6)/3

The above expression shows the value of y lies above the line y =5x/3-2 which implies graph A is correct.

Thus, Graph A represents the given inequality 3y−5x>−6. Option A is correct.

My guess is that 10/36 students weren't playing sports.

Answer:

Beatrice traveled the last 220 miles of the trip at 55 miles per hour. The entire trip covered 430 miles and took 7 hours. What was her rate for the first 210 mile?

Let Beatrice's average speed for the first 210 miles = S

220/55 + 210/S

Solve for S:

4 + 210/S = 7

Bring 4 + 210/S together using the common denominator S:

(2 (2 S + 105))/S = 7

Multiply both sides by S:

2 (2 S + 105) = 7 S

Expand out terms of the left hand side:

4 S + 210 = 7 S

Subtract 7 S + 210 from both sides:

-3 S = -210

Divide both sides by -3:

+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=1

ab=−56

Since ab is negative, a and b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −56.

Step-by-step explanation:

You can tell how to isolate a variable by listing the operations done to it, as prescribed by the order of operations. Then, you work backwards up the list performing inverse operations as you go.

__

Additional comment

Where mixed powers of the variable are involved, as in polynomials of degree higher than 1, there is generally not an inverse operation you can use to isolate the variable. Rather, special forms are used that facilitate isolating the variable. The variable in a quadratic, for example, can be isolated by "completing the square." Similar procedures are available for solving cubic and quartic equations, though those tend to be somewhat more complicated.

There are many kinds of equations in which there are no methods for isolating the variable. In general, any mix of polynomial terms and logarithmic, exponential, or trigonometric function terms are in that category: x +sin(x) -3 = 0, for example. (A graphing calculator shows the solution is near x=2.18, where the angle is in radians.)

Answer:

location after 2 minutes dive from the surface = -440 feet

Step-by-step explanation:

We are told that he dives 1,760 feet in 8 minutes.

Now, we are told that he dives down at a constant rate.

Thus means that the distance he dives per minute can be gotten.

Distance dived per minute = 1760/8 = 220 feet/minutes

Now, we want to find the location of the penguin in relation to the surface 2 minutes after beginning his dive.

Thus;

Distance after 2 minutes = 220 feet/minutes × 2 minutes = 440 feet

Now, because the dive is below the surface, the location will be negative.

Thus, location after 2 minutes dive from the surface = -440 feet

[tex]131=6w[/tex]

Step-by-step explanation:

[tex]l=length\\\\w=width\\\\\Longrightarrow l=2w\\\\\Rightarrow Perimeter=l+l+w+w\\\\P=2l+2w\\\\P=2(2w)+2w\\\\P=4w+2w\\\\P=6w\\\\P=131\\\\131=6w\\\\w=\frac{131}{6}\\\\w=21.8\overline{3}\\\\l=43.\overline{6}[/tex]

Answer:

A) l = 2 * w

B) 131 = 2l + 2w

B) 2l = 131 -2w

B) l = 65.5 -w

Substituting this into A)

65.5 -w = 2w

3w = 65.5

width = 21.8333333333

length = 43.6666666666

Double - Check

131 = 2 * 21.833333333 + 2 * 43.6666666666

131  = 43.6666666  + 87.33333333

Step-by-step explanation:

Where are given that the cost of medical service delivery is given by the expression

c=0.5m+10

m= the number of miles

when the number of miles is 75.5 mile we want to find the cost

put m=75.5 in the expression

c=0.5(75.5)+10

solving for c we have

c=37.75+10

c=47.75

Therefore the cost will be $47.75 for a distance of 75.5miles
