A cube has 6 sides so we multiply the measurement of one of the sides by 6 to get the surface area of the whole cube.Let f(x) = -2x + 4 and g(x) = -6x - 7. Find f(x) - g(x).
can anybody help me with this? show your work if you can too, please!
Answer:
f(x) -g(x) = 4x +11
Step-by-step explanation:
Substitute the given expressions and simplify.
f(x) -g(x) = (-2x+4) -(-6x-7)
Eliminating parentheses, we get ...
f(x) -g(x) = -2x +4 +6x +7 = (-2+6)x +(4 +7) . . . . combining like terms
f(x) -g(x) = 4x +11
A local newspaper compiles data on the number of days, X, people in a neighborhood receive the newspaper. The probability distribution for the data is shown in the table below. What is the probability that a randomly chosen person receives the newspaper at least one day per week? A probability distribution has number of days on the x-axis and probability on the y-axis. The probability of 0 days is 0. 17; 1 day is 0. 16; 2 days is 0. 14; 3 days is 0; 4 days is 0; 5 days is 0. 12; 6 days is 0; 7 days is 0. 41. 16% 33% 41% 83%.
The probability for a person to receive the newspaper at least one day per week is 83 %. Then the correct option is D.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
A local newspaper compiles data on the number of days, X, people in a neighborhood receive the newspaper.
The table will be
X P(X)
0 0.17
1 0.16
2 0.14
5 0.12
7 0.41
We are asked the probability for a person to receive the newspaper at least one day per week. Then the probability will be
Probability = 0.16 + 0.14 + 0.12 + 0.41
Probability = 0.83
Probability = 83 %

The length and the width of a rectangle are in the ratio of 5 to 2, and the area is 1,000 sq. ft. Find the dimensions.
Step-by-step explanation:
l = length
w = width
l/w = 5/2
l = 5w/2
l×w = 1000ft²
(5w/2)×w = 1000
5w²/2 = 1000
5w² = 2000
w² = 400
w = 20ft
l = 5w/2 = 5×20/2 = 5×10 = 50ft
the length is 50ft.
the width is 20ft.

Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredients. His recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze. How many 1/4 cup scoops of sugar does he need?
Answer: The answer is 15.
Step-by-step explanation:
In the question, we are informed:
2 1/2 cups sugar for the cake and 1 1/4 cup sugar for the vanilla icing are called for in Mr. Smith's recipe.
1st step
We total the amount of sugar he'll require.
1 1/4 + 2 1/2
(1/2 + 1/4) + (2 + 1)
= 3 + (2 Plus a quarter)
a total of 3 3/4 cups of sugar
2nd Step
How many 1/4 cup sugar scoops does he require?
This can be calculated as follows:
1/4 cup sugar 3 3/4 cup sugar
= 15/4 x 1/4 = 15/4 x 1/4 = 15/4 x 1/4 =
= 15/4/4 = 15/4/4 = 15/4/4 = 15/4/4 = 15/4
15
As a result, he'll require 15, 1/4 cup sugar scoops.

Step-by-step explanation:
you have been transported to a jungle-scape in the body of a mathematician. you build a catapult to launch messages to your team, who are on the other side of a deep and wide revine. the graph below shows the trajectory of your message. you launch the message 7 feet east of a tree that is 5 feet west of the edge of the revine. the ravine is 12 feet wide.
The trajectory of your message illustrates a quadratic function
The equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]
How to determine the equation of the graph?The trajectory graph (see attachment) is a quadratic function that passes through the following points:
(x,y) = (7,0) and (27,0)
And the vertex is:
(h,b) = (17,20)
A quadratic function is represented as:
[tex]y = a(x - h)^2 + b[/tex]
So, we have:
[tex]y = a(x - 17)^2 + 20[/tex]
Substitute (7,0) for (x,y)
[tex]0 = a(7 - 17)^2 + 20[/tex]
Evaluate
[tex]0 = 100a + 20[/tex]
Collect like terms
[tex]100a = -20[/tex]
Divide both sides by 100
[tex]a = -\frac 15[/tex]
Recall that:
[tex]y = a(x - 17)^2 + 20[/tex]
So, we have:
[tex]y = -\frac 15(x - 17)^2 + 20[/tex]
Hence, the equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]

The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4
What is a quadratic function?A quadratic function is in the form:
y = ax² + bx + c
Given that:
f(x) = 2x² + 8x - 3, hence:
The zero is at:
2x² + 8x - 3 = 0
2x² + 8x = 3
Dividing through by 2:
x² + 4x = 3/2
add to both sides 4:
(x + 2)² = 3/2 + 4
(x + 2)² = 11/4
x + 2 = ±√11/4
x = -2 ±√11/4
The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4

Answer:

Step-by-step explanation:
[12] [tex]7x^2+75+50[/tex]
The first term is, 7x^2 its coefficient is 7 .The middle term is, +75x its coefficient is 75 .The last term, "the constant", is +50First, Multiply the coefficient of the first term by the constant 7 × 50 = 350
Then, find two factors of 350 whose sum equals the coefficient of the middle term, which is 75 .
Then, Rewrite the polynomial splitting the middle term using the two factors 5 and 70
7x^2 + 5x + 70x + 50
Add up the first 2 terms, pulling out like factors :
x × (7x+5)
Add up the last 2 terms, pulling out common factors :
10 × (7x+5)
(x+10) • (7x+5)
Hence, Answer = 7x + 5

A perfect square trinomial is a quadratic equation of the form
[tex]ax^2+bx+c=0[/tex]
and a result of squaring a binomial. This means that the first and third term of the trinomial is equal to the square of the first and second term of a binomial. Therefore, in order to determine the value of the third term, we can use the method of completing the square in which the formula is
[tex]c=(\frac{b}{2a})^2[/tex]
where c is the constant and b and a are the coefficients of the first and the second term.
The trinomial 9x^2+72x+144 is a perfect square trinomial, because it's discriminant is equal to zero
Δ=b 2 −4ac=72 2 −4(9)(144)=0

d1 = length of diagonal 1
d2 = length of diagonal 2

A scale model of a ramp is a right triangular prism as given in this figure. In the actual ramp, the triangular base has a height of 1.2 feet.
What is the surface area of the actual ramp, including the underside?
Enter your answer as a decimal in the box.
Answer:
16.8
Step-by-step explanation:
The scale factor is a ratio. The surface area of the real ramp is 16.80 ft².
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
As we know that the height of the real ramp is 1.2 feet, while the height of the drawing is 6 cm, therefore, the scale factor can be written as,
[tex]\rm Scale\ factor = \dfrac{\text{Area of Image}}{\text{Area of pre-image}}=\dfrac{1.2 \ feet}{6\ cm} = 0.2[/tex]
Now, the area of the pre-image can be written as,
[tex]\rm \text{Area of pre-image} = 2triangles+ 2 rectangle + 1 rectangle\ at\ base[/tex]
[tex]= 2(0.5 \times 6 \times 16) + 2(10 \times 9) + (16 \times 9)\\\\= 2(48)+2(90)+144\\\\= 96 + 180 + 144\\\\ = 420\ cm^2[/tex]
Further, the area of the actual ramp can be written as,
[tex]{\text{Area of pre-image}} \times \rm Scale\ factor = \text{Area of Image}\\\\ \text{Area of Image}= 420 \times (0.2)^2 \\\\ \text{Area of Image}= 16.8\ ft^2[/tex]
Hence, the surface area of the real ramp is 16.80 ft².

What are the measures of angles 1,2, and 3?
Step-by-step explanation:
this is unclear.
did this mean the left and the right sides are the same length (and parallel)?
it seems then they are 2 congruent triangles and the whole shape a parallelogram.
remember, the sum of all 3 angles in any triangle is always 180°.
so,
angle 1 = 180 - 70 - 60 = 50°
the congruence principle then makes angle 3 = angle 1 = 50°.
and then angle 2 must be 70°, as 70° + angle 3 = angle 1 + angle 2.
if I misunderstood, then angle 3 and then angle 2 can't be determined.
