Xin leans a 26-foot ladder against a wall so that it forms an angle of 78^{\circ} ∘ with the ground. What’s the horizontal distance between the base of the ladder and the wall? Round your answer to the nearest hundredth of a foot if necessary
The ladder and the wall it leans on are illustrations of right triangle
The horizontal distance from the base of the ladder is 5.41 feet
How to determine the horizontal distance?The given parameters are:
Length (L) = 26 feet
Angle of elevation (θ) = 78 degrees
The horizontal distance (D) is calculated using the following cosine ratio
cos(θ) = D/L
Substitute known values
cos(78) = D/26
Make D the subject
D = 26 * cos(78)
Multiply
D = 5.41
Hence, the horizontal distance from the base of the ladder is 5.41 feet

What two numbers multiply to egalitarian -35 and add to equal -2
Using a system of equations, it is found that the numbers are 5 and -7.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, we say that the numbers are x and y.
They multiply to -35, hence:
xy = -35.
They add to -2, hence:
x + y = -2 -> y = -2 - x
Replacing on the first equation:
x(-2 - x) = -35
-x² - 2x + 35 = 0
x² + 2x - 35 = 0
(x + 7)(x - 5) = 0
x = -7 -> y = 5
x = 5 -> y = -7
Hence the numbers are 5 and -7.

Find the coordinates of the turning point for the equation of the graph below
y=x^2– 16x +39
=
Answer:
x = 8 - sqrt(y + 25)
Step-by-step explanation:
Step-by-step explanation:
comparing given equation with ax^2+bx+c;
a=1 b=-16 c=39
now,
x coordinate of vertex = -b/2a
= 16/2*1
= 8
again,
y coordinate of vertex = (8)^2-16(8)+39
=-25
Therefore, the turning point is (8,-25).

Answer:
(0,4).
Step-by-step explanation:
The point (0, 4) is on the y axis ( as x = 0) so the answer is (0,4).

Answer:
32 x 2
---------- = 16
.....4
To start off we can do 32 x 2.
32 x 2 = 64
Next, we divide 64 by 4 to equal the fraction 32 x 2 / 4.
64 divided by 4 = 16
In conclusion the fraction 32 x 2 / 4 is equal to 16.

What shape has been used to form the quilt pattern below?
Answer:
Right Triangles
Step-by-step explanation:
This is because in a right angled triangle, there is one angle that is equal to 90 degrees, and 2 that are 45 degrees each.
These 45 degree corners make up the corners of the square (45+45 = 90 = right angle = corner of square)
Hope this makes sense.

Levi just started a running plan where he runs 8 miles the first week and then
increases the number of miles he runs by 5% each week. If he keeps up this plan for
19 weeks, how many total miles would Levi have run, to the nearest whole number?
Answer:
244 miles (nearest whole number)
Step-by-step explanation:
This scenario can be modeled as a geometric series.
From the information given:
[tex]a[/tex] (initial term) = 8 (miles)[tex]r[/tex] (common ratio) = 1.05 (as number of miles increases by 5% each week)[tex]n[/tex] = 19 (as the plan is for 19 weeks)The formula for the sum of the first n terms of a geometric series is:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Therefore, the sum of the first 19 terms is:
[tex]\implies S_{19}=\dfrac{8(1-1.05^{19})}{1-1.05}[/tex]
[tex]\implies S_{19}=244.3120313...[/tex]
Solution244 miles (to the nearest whole number)
So
It's a GP
we need Sum
[tex]\\ \rm\Rrightarrow S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
[tex]\\ \rm\Rrightarrow S_{19}=\dfrac{8(1-1.05^{19})}{1-1.05}[/tex]
[tex]\\ \rm\Rrightarrow S_{19}=\dfrac{−12.21560156300510578244137725830078125}{-0.05}[/tex]
[tex]\\ \rm\Rrightarrow S_{19}=244.312\approx 244mi[/tex]

5. If p(x) = 1/2(x–5)^2+ 14, what is the
value of p(3)?
Answer:
i think since p(x) = p(3)
Step-by-step explanation:
then p(3) = 3
where you see x add 3
so 1/2(x-5)^2 + 14
1/2(3-5)^2 + 14
1/2(-2)^2 + 14
1/2 x 4 + 14
cancel out 4 by 2 ( divide)
you get 2 + 14
16.
p(x) = 16.

The binomial factor of the equation [tex]\rm 9x^2 -64[/tex] is 3x-8.
What is a binomial factor?The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.
Factoring binomials means breaking down a binomial expression into its simplest form.
Binomials are algebraic expressions with two terms.
The given binomial is;
[tex]\rm 9x^2 -64[/tex]
The binomial is determined in the following steps given below.
[tex]\rm =9x^2 -64\\\\= (3)^2x^2-8^2\\\\= (3x)^2-8^2\\\\= (3x-8)(3x+8)[/tex]
