Answer:
Given: If triangle CFH is similar to triangle TDM with a scale factor of 4: 5.
Similar triangle states that the two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
then by definition, we have;
[tex]\frac{CF}{TD}= \frac{FH}{DM} =\frac{CH}{TM}= \frac{4}{5}[/tex] .....[1]
From the figure, we have;
CF = x +7 , FH = x-1 , CH = x+3 , TD = 2x -13 , DM = x+6 and TM = x+ 11
Solve for x;
[1] ⇒ [tex]\frac{CF}{TD} =\frac{4}{5}[/tex]
Substitute the value of CF and TD to solve for x;
[tex]\frac{x+7}{2x-13} = \frac{4}{5}[/tex]
By cross multiply we get;
[tex]5 (x+7) = 4(2x-13)[/tex]
Using distributive property : [tex]a\cdot(b+c) = a\cdot b + a\cdot c[/tex]
5x + 35 = 8x - 52
Subtract 35 on both sides we get;
5x + 35 -35 = 8x - 52 -35
Simplify:
5x = 8x - 87
Subtract 8x on both sides we get;
5x -8x = 8x -87 -8x
Simplify:
-3x = -87
Divide both sides by -3 we get;
x = 29
To find the perimeter of triangle CFH;
Sides are:
CF = x + 7 = 29 + 7 = 36 units
CH = x+3 = 29 +3 = 32 units
FH = x -1 = 29 -1 = 28 cm.
Perimeter of any triangle is the sum of all the sides of the triangle.
Perimeter of triangle CFH = CF + CH + FH = 36 + 32 + 28 = 96 units
therefore, the perimeter of triangle CFH is, 96 units.
Without the perimeter of triangle TDM, we can't calculate the perimeter of triangle CFH using only the scale factor. When additional information is provided such as the length of a side in both triangles, it will be possible.
Explanation:The subject of this question is mathematics, specifically regarding similar triangles and the calculation of a triangle's perimeter when the scale factor is provided. In this case, the triangles CFH and TDM are similar with a scale factor of 4:5.
When triangles are similar, corresponding sides are proportional which means one side of triangle CFH is 4/5 the length of the corresponding side of triangle TDM. If we were given the perimeter of triangle TDM, we would multiply by the ratio (4/5 or 0.8) to get the perimeter of triangle CFH. However, without this extra information, we aren't able to provide the exact perimeter of triangle CFH.

You go to a school dance. There is an entrance fee, and there are slices of pizza for sale. After having 1 slice of pizza, you have spent a total of $6. After having 2 more slices of pizza, you have spent a total of $10. Write an equation that represents the total cost y after buying x slices of pizza at the dance.
The equation representing the total cost after buying x slices of pizza
is [tex]\( C(x) = E + x \times P \)[/tex].
Let's denote the entrance fee as E (in dollars) and the cost of each slice of pizza as P (also in dollars). Given the problem, we can write the following equations based on the given information:
After having 1 slice of pizza, the total cost is $6:
[tex]\(E + 1 \times P = 6\)[/tex]
After having 2 more slices of pizza (total 3 slices), the total cost is $10:
[tex]\(E + 3 \times P = 10\)[/tex]
To find the equation that represents the total cost (y) after buying x slices of pizza (let's call it C(x), we need to generalize the pattern observed in the given equations.
Notice that the entrance fee remains constant regardless of the number of slices of pizza bought. So, we can write the equation as:
[tex]\[ E + x \times P = C(x) \][/tex]
Substituting the values given in the problem:
[tex]\[ C(x) = E + x \times P \][/tex]
So, the equation representing the total cost after buying x slices of pizza
is [tex]\( C(x) = E + x \times P \)[/tex]. This equation gives the total cost (y) as a function of the number of slices of pizza bought (x).

Graph the function represented in the table on the coordinate plane.
x: −2, −1, 0, 1, 2
y: 8, 5, 2, −1 , −4
please make answer a picture, im a bit dumb
Step-by-step explanation:
We are given the co-ordinates,
x : -2, -1, 0, 1, 2
y : 8, 5, 2, -1, -4
According to the graph, we see that this function represents a straight line.
The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.
So, taking any two points we will find the equation of the straight line.
Consider, (0,2) and (1, -1). Now, slope is given by,
m = [tex]\frac{-1-2}{1-0}[/tex]
i.e. m = -3
Now, we will find the y-intercept of this equation using (0,2) and m = -3,
i.e. y = -3x + c
i.e. 2 = c
Hence, the equation of the straight line is y = -3x + 2.

Given: ABC is a right triangle with right angle C. AB=18 centimeters and m∠A=22∘ .
What is BC ?
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
BC = 6.7 cm (rounded to nearest tenth)
Explanation:
Given: ABC is a right triangle with right angle C as shown below.
Side AB=18 cm and m∠A=22°.
Using Sine ratio in triangle ABC to find BC.
Sine ratio is defined as the ratio of the opposite side of a right triangle to the hypotenuse.
i.e
[tex]\sin A = \frac{Opposite side}{Hypotenuse side}[/tex]
Let BC = x (opposite side) and AB = 18 cm(Hypotenuse side)
then;
[tex]\sin 22^{\circ} = \frac{x}{18}[/tex]
[tex]0.37460659341 = \frac{x}{18}[/tex]
Multiply both sides by 18 we get;
[tex]x = 0.37460659341 \times 18 = 6.74291868[/tex]
therefore, value of BC (nearest tenth place) is, 6.7 cm

The perimeter of the rectangle is 42m.
Explanation:To find the perimeter of the rectangle, we need to know the lengths of its sides. From the given information, we know that the area of the rectangle is 108m^2 and its diagonal is 15m. We can use this information to find the lengths of the sides.
Let the length of the rectangle be 'l' and the width be 'w'.
Given, lw = 108 and sqrt(l^2 + w^2) = 15.
Squaring both sides of the second equation, we get l^2 + w^2 = 225.
Since lw = 108, we can solve the quadratic equation l^2 - 108l + 225 = 0 to find l. In this particular case, the quadratic factors as (l - 9)(l - 12) = 0, so l = 9 or l = 12.
Substituting the values of l in the equation lw = 108, we find w = 12 or w = 9.
Since the perimeter is the sum of all the sides, the perimeter of the rectangle is (2l + 2w) = (2 * 9 + 2 * 12) = 42m.

Can anyone walk me through this?
Assuming that we are solving in terms of n.
Start by distributing:
2(n + 5)
(2*n) + (5*2)
2n + 10 = -2
Subtract 10 to start toward isolating your variable:
2n = -12
Divide by two to finish solving:
n = -6
Answer:
n=-6
Step-by-step explanation:
2(n+5)=-2
distribute the 2 to the numbers in the parentheses:
2n+10=-2
Get the n factor alone, subtract 10 from both sides:
2n=-12
Now you just want the n alone so you are going to use the inverse operation on 2n to both sides: 2n/2=-12/2
n=-6

It is apparently obvious we could expand the bracket and integrate term-by-term. This method would work but is very time consuming (and you could easily make a mistake) so we use a different method: integration by substitution.
Integration by substitution involves swapping the variable [tex]x[/tex] for another variable which depends on x: [tex]u(x)[/tex]. (We are going to choose [tex]u[/tex] for this question).
The very first step is to choose a suitable substitution. That is, an equation [tex]u=f(x)[/tex] which is going to make the integration easier. There is a trick for spotting this however: if an integral contains both a term and it's derivative then use the substitution [tex]u=\text{The Term}[/tex].
Your integral contains the term [tex]x^2 + 3[/tex]. The derivative is [tex]2x[/tex] and (ignoring the constants) we see [tex]x[/tex] is also in the integral and so the substitution [tex]u=x^2+3[/tex] will unravel this integral!
Step 2: We must now swap the variable of integration from x to u. That means interchanging all the x's in the integrand (the term being integrated) for u's and also swapping (dx" to "du").
[tex]u=x^2+3 \Rightarrow \frac{du}{dx}=2x \Rightarrow dx = \frac{1}{2x} du[/tex]
Then,
[tex]\int 3x(x^2+3)^4 \ dx = \int 3x \cdot u^4 \cdot \frac{1}{2x} du = \int \frac{3}{2}u^4\ du[/tex].
The substitution has made this integral is easy to solve!
[tex]\int \frac{3}{2}u^4\ du= \frac{3}{10}u^5 + C[/tex]
Finally we can substitute back to get the answer in terms of x:
[tex]\int 3x(x^2+3)^4 \ dx = \frac{3}{10}(x^2+3)^5+C[/tex]

write the following inequality in slope-intercept form. 5x-5y≥70
To rewrite the inequality 5x - 5y ≥ 70 in slope-intercept form, we solve for y by subtracting 5x from both sides and then dividing by -5, resulting in y ≤ x - 14, with a slope of 1 and a y-intercept of -14.
Explanation:The question is asking to rewrite the inequality 5x - 5y ≥ 70 in slope-intercept form. The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. To convert the given inequality into this form, we need to solve for y.
Steps to rewrite the inequality in slope-intercept form:
Subtract 5x from both sides of the inequality: -5y ≥ -5x + 70Divide every term by -5 to solve for y: y ≤ x - 14. Note that when dividing by a negative, the inequality symbol reverses its direction.The inequality in slope-intercept form is y ≤ x - 14. The slope is 1 and the y-intercept is -14.
