A flagpole is 12 feet tall. Its shadow is 14 ft long. How far is it from the top of the
flagpole to the end of its shadow?
Answer:
Step-by-step explanation:
AC = length of flagpole = 12 ft
AB = length of shadow = 14 ft
BC = length from the top of the flagpole to the end of the shadow = x ft
Use Pythagorean theorem to find the length of x,
x² = AC² + BC²
= 12² + 14²
= 144 + 196
= 340
x = √340
x = 18.4 ft

Answer:
x = 698.771
step-by-step explanation:
[tex]\sf \rightarrow \log _{2x}\left(5^{\dfrac{3}{2}}\right)=\dfrac{1}{3}[/tex]
apply ln rules
[tex]\sf \rightarrow \dfrac{\ln \left(5^{\dfrac{3}{2}}\right)}{\ln \left(2x\right)}=\dfrac{1}{3}[/tex]
cross multiply
[tex]\sf \rightarrow \ln \left(5^{\dfrac{3}{2}}\right)\cdot \:3=\ln \left(2x\right)\cdot \:1[/tex]
simplify using calculator
[tex]\sf \rightarrow 7.24247 = ln(2x)[/tex]
shift sides
[tex]\sf \rightarrow e^{7.24247 }= 2x[/tex]
divide both sides by 2
[tex]\sf \rightarrow 698.771= x[/tex]
Answer:
[tex]x=698.771[/tex]
Step-by-step explanation:
[tex]log_{2x} (5\frac{3}{2})=\frac{1}{3}[/tex]
[tex](5\frac{3}{2})*3=In(2x)*1[/tex]
[tex]7.24247=In(2x)[/tex]
[tex]e^{7.24247}=2x[/tex]

Consider the system of equations.
2.+y=0
- 3x + 4y= 22
How do you solve the system of equations with Cramer's rule?
Drag a value or determinant expression into each box to correctly
solve the system using Cramer's rule.
I've arranged the tiles into the correct positions, and wrote in the final result for each x and y.
The basic idea is to divide determinants as the vertical bars indicate (they aren't absolute value bars).
In each denominator is the determinant of the matrix [tex]\begin{bmatrix}2 & 1\\-3 & 4\end{bmatrix}[/tex] which are the coefficients of the left hand side of each original equation given to you.
-------------
The numerators are a slight variation of this matrix. The x determinant will have you replace the first column with 0 & 22 getting [tex]\begin{bmatrix}0 & 1\\22 & 4\end{bmatrix}[/tex] which helps figure out the x solution. The y solution is similar as well, but we replace the y column instead of the x column. So that explains the [tex]\begin{bmatrix}2 & 0\\-3 & 22\end{bmatrix}[/tex]
After you have the proper determinants set up, you just evaluate each determinant using the formula
[tex]\begin{vmatrix}a & b\\ c & d\end{vmatrix} = a*d - b*c[/tex]
and then simplify the results.
Marco made $50 for every 2 hours he works, how much will he make in 10 hours?
Answer:
$500
Step-by-step explanation:
if Marco gets $50 for every 2 hours and it say how much he'll have every 10 hours what your gonna do is multiply 10 by 50 so 10×50= 500 so Marco will make $500 every 10 hours
$250 will he make in 10 hours for the work that Marco has done.
What is multiplication?When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however, other symbols like the "*" sign are also occasionally used.
The information that is provided is:
Marco made $50 for the two hours he is working for.
For one hour of the work that he is doing the amount that he will be paid is
= 50 / 2
$25
For working 10 hours Marco will earn
= 10*25
$250

The total percent discount offered by the merchant is 57.12%.
What is the total percent discount?A discount is when the price of an items is reduced. It makes a good cheaper when a discount is applied.
The percent change in price after the first discount = 100% - 32% = 68%
The final price after the second discount = (100 - 16%) x 68%

a = −b
b = −c
a + b + c = 8
Answer:
8
Step-by-step explanation:
if a = -b, then -a = b.
plug that into the (b = -c) problem, and you get -a = -c, or a = c
if a and c ar equal, then and b = -c, b also equals -a.
the problem then becomes a - b +c, where a = 8, c = 8, and b = -8
a = -b -> 8 = -(-8)
b = -c -> -8 = -(8)
a = c -> 8 = 8

The diameter of a circle is 28 millimeters. What is the circle's area
Use 3.14 for .
Answer:
615.44 mm²
Step-by-step explanation:
Before finding the area of the circle, first, let us find the radius of the circle.
Given that,
diameter ⇒ 28 mm
Therefore,
d = 2r28 = 2r
Divide both sides by 2.
14mm = radius
And now, let us find the area.
The formula to find the area of the circle is :
Area = π r²Let us solve now.
Area = π r²
= 3.14 × 14 × 14
= 43.96 × 14
= 615.44 mm²
Determine the discriminant for the quadratic equation -3=x2+4x+1. Based on the
discriminant value, how many real number solutions does the equation have?
Discriminant = b2-4ac
Given -
x² + 4x + 1 = -3
To find -
the discriminant for the quadratic equation and to find how many real number solutions does the equation have. If it's discriminant = b² - 4ac
Concept applied -
As we know, Discriminant = b² - 4ac
A quadratic equation ax²+ bx + c = 0 has -
two distinct real roots, if b² - 4ac > 0 , two equal roots (i.e., coincident roots), if b²- 4ac = 0, and no real roots, if b² - 4ac < 0.Solution -
Solving the quadratic equation to bring it in the form of ax² + bx + c = 0,
➛ x² + 4x + 1 = -3
➛ x² + 4x +3 + 1 = 0
➛ x² + 4x + 4 = 0
Here,
a = 1, b = 4 and c = 4.
Putting the values in the the formula, b²- 4ac = 0.
➙ (4)²- 4(1)(4)
➙ 16- 16
➙ 0
As, b²- 4ac = 0 hence the quadratic equation will have two equal roots (i.e., coincident roots).
Answer:
1 aka b

find the first six terms of the geometric sequence-1, -3, -9, _, _, _
Hey there!
A geometric sequence is where we use multiplication or division to get to the next term.
In this case, we use multiplication (we multiply every term by 3)
So we have
-1, -3, -9, -27, -81, -243...
Steps:
Since we multiply every term by 3, we multiply -9 times 3. then we multiply the product of 9 & 3 times 3, and so on...Hope everything is clear.

D and E are the mid-points of the sides AB and AC of ΔABC and O is any point
on side BC. O is joined to A. If P and Q are the mid-points of OB and OC
respectively, then prove that DEQP is a parallelogram.
Check out the diagram below.
Since D and E are midpoints of AB and AC this means midsegment DE is parallel to side BC. Furthermore, it means DE is parallel to PQ because PQ is entirely on BC.
---------
Note how I drew a line from A to O. This forms two triangles ABO and ACO
For triangle ABO, segment DP is a midsegment because D and P are midpoints of AB and OB respectively. This means side DP is parallel to side AO. Keep this in mind as we'll use it later.
For triangle ACO, segment EQ is parallel to AO because EQ is a midsegment for similar reasons as already mentioned (E and Q are midpoints of AC and OC respectively). So this must mean that AO is parallel to EQ
Now chain the arguments together: if DP || AO and AO || EQ, then DP || EQ by the transitive property.
-----------
In short, we've proven two things
DE is parallel to PQDP is parallel to EQThis is enough to conclude that DEQP is a parallelogram. By definition, a parallelogram has two pairs of opposite parallel sides.
