Answer:
Step-by-step explanation:
The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.
DG*DE/2 = GE * DF/2 Multiply both sides by 2
DG*DE = GE * DF
DG = 8
DE = 15
GE = 17
8*15 = 17* DF
120 = 17 * DF Divide by 17
120/17 = DF
DF = 7.06

if the distance between town a and b is 1350 KM and the distance between town A and C is in the same direction is approximately two fifth of this. what is the approximate distance of town B and C
Answer:
BC = 810 KM
Step-by-step explanation:
It is 2/5 from A to C so the remaining distance 1 -2/5 = 5/5 -2/5 = 3/5 is the distance from C to B
BC = 3/5 * 1350
BC = 810 KM
I need help guys like rn please someone!!
Answer:
B
Step-by-step explanation:
The correct answer is B, because you have -4 +(-6)+(-2) which is really just
-4-6-2 which is -12. Think of it as getting rid of the plus sign and just leaving the negative sign. Which this would make the answer to the equation be -12, but for the answer of the question, it would be B because it is accumulating the drops in temperatures making the numbers go down in temperature, therefore making them negative.
A is not the answer because although it is similar to letter B, the difference is the final sentence, "What was the overall change in temperature?" Since -4 is listed as the pre-existing temperature, that would make -6 - 2 be equal to negative eight (-8).
C is not the answer because it includes a temperature rising by 18 degrees.
D is not the answer either because it is saying the temperature rose, which is shouldn't have risen.
The only time C and D could be right, is if they included bigger number that equaled out to negative twelve (-12), like saying the temperature rose 18 degrees, but fell by 26 degrees by midnight, that would make the equation look like -4 + 18 - 26 = - 12
Even in that case, C and D would be wrong immediately because of the use of numbers outside of the expression given.
Hope this helps!
The product 2+bi)(3+2i) is equal to 13i. What is the value b?
Answer:
[tex]b = 3[/tex]
Step-by-step explanation:
We are given that:
[tex](2 + bi)(3+2i) = 13i[/tex]
And we want to determine the value of b.
First, expand:
[tex]\displaystyle \begin{aligned} (2+bi)(3+2i)&=2(3+2i)+bi(3+2i) \\ &= (6+4i)+(3bi+2bi^2) \\ &= (6+2b(-1))+(4i+3bi) \\ &= (6-2b) + (4+3b)i\end{aligned}[/tex]
Therefore, we can write that:
[tex](6-2b) + (4+3b)i = 0+ 13i[/tex]
If two complex numbers are equivalent, their real and imaginary parts must be equivalent. Hence:
[tex]6-2b = 0 \text{ and } 4+3b = 13[/tex]
Solve for each case:
[tex]b=3 \text{ and } b=3[/tex]
The two solutions are equivalent, hence such a number b exists.
In conclusion, b = 3.

DUE SOON HELPPP PLZzz
Answer:
C
Step-by-step explanation:
It looks impossible to tell if you don't know one simple fact. You have to know that the Plane that contains WTSR and V is opaque which means you can't see through it. So the line that goes through it (containing WQ) is partially not seen.
It is represented by a dashed line that shows the line is there, but it is invisible.
So Q is on the plane, but W is not. W is the answer.

[tex]\\ \rm\longmapsto 12+2[/tex]
[tex]\\ \rm\longmapsto 14[/tex]
Answer:
14
Step-by-step explanation:
f(x) = 3x² - x
To find f(-2), substitute -2 for x into the function f.
f(-2) = 3(-2)² - (-2)Now, use PEMDAS to evaluate the function.
Start by evaluating the exponent.
f(-2) = 3(4) - (-2)Next, multiply 3 and 4 and -2 by -1.
f(-2) = 12 + 2Add the two terms together.
f(-2) = 14The correct answer is f(-2) = 14.
please guys someone help i need the answer
Step-by-step explanation:
2x + y + x+ 2y = 180
3x + 3y = 180
3y +20+2x+y=180
4y + 2x = 160
3x + 3y = 180
2x + 4y = 160
elimination
6x + 6y= 360
6x + 12y = 480
= 6y = 120
y= 20
substitute
3x + 3y = 180
3x + 3(20)= 180
3x + 60 = 180
3x = 120
x= 40
x+2y
40+2(20)=80
<4=<8= 80°

Help me solve the following formula for v1
Answer:
v1 = at + v0
Step-by-step explanation:
We want to end up with a formula that looks like v1 = algebraic expression
Start by multiplying both sides of the given formula by t, to eliminate fractions:
at = v1 - v0
Next we isolate v1 by adding v0 to both sides of the above equation:
at + v0 = v1 - v0 + v0, or v1 = at + v0
Answer:
V1=at+V0

What is the equation of the line that passes through the point (8,1) and has a slope
of –3/4?
Answer:
[tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is already given as [tex]-\frac{3}{4}[/tex] so all we have to do is solve for y-intercept
First, write the equation in slope-intercept form
[tex]y=-\frac{3}{4}x+b[/tex]
Next, use the point to substitute the x and y value and solve for the y-intercept
[tex]y=-\frac{3}{4} x+b[/tex] where b = y-intercept
point: (8, 1)
[tex]1=-\frac{3}{4}(8)+b[/tex]
Then multiply 8 and -3/4
[tex]1=-6+b[/tex]
Finally, solve for the b (y-intercept)
b = [tex]1--6[/tex]
b = 7
so the y-intercept is 7
And the equation of the line that passes through the point (8, 1) and has a slope of -3/4 is [tex]y=-\frac{3}{4}x+7[/tex]
Three-quarters of a number is 2 bigger than two-thirds of the number.
Determine the number.
Answer:
0
Step-by-step explanation:
3/4.x = 2. 2/3.x
↔ x = 0
The required number after simplification of the given statement of the equation is equal to 24.
Let's call the number we want to find "x."
According to the given information:
Three-quarters of the number is 2 bigger than two-thirds of the number.
Mathematically, we can express this as the following equation:
(3/4) × x = (2/3) × x + 2
Now, let's solve for "x":
Get rid of the fractions by multiplying everything by the least common multiple (LCM) of 4 and 3, which is 12.
12× (3/4) × x = 12 × (2/3) × x + 12× 2
Simplify both sides:
9x = 8x + 24
Isolate the "x" term on one side. To do this, we need to move the 8x to the left side by subtracting 8x from both sides:
9x - 8x = 8x + 24 - 8x
Simplify further:
x = 24
Therefore, the number after simplification is 24.
