Find the value of x in the figure below.
(8x + 5)°
(13x – 14)°
Answers
Answer:
x = 9
Step-by-step explanation:
The question is shown in the attached figure.
We can see that, (8x + 5)° and (13x – 14)° forms a linear pair. It would mean that,
(8x + 5)° + (13x – 14)° = 180°
21x-9 = 180°
21x = 180° + 9
21x = 189
x = 9
Hence, the value of x is 9.
The midpoint of AB is M(4, -2). One endpoint is A(-2, 6). What is the other endpoint for B?
Answers
Answer:
endpoint for B is (10,-2)
Step-by-step explanation:
M={(x1+x2)/2,(y1+y2)/2}
(4,2)={-2+x2/2,6+y2/2)
By equating the x coordinates
4=-2+x2/2
8=-2+x2
8+2=x2
x2=10
By equating the y coordinates
2=6+y2/2
4=6+y2
4-6=y2
y2=-2
Therefore the endpoint for B is (10,-2)

in 1990 the estimated population of pittsburgh, pennsylvania, was 369,879. in 2000 the estimated population was 334,563. find the percent of decrease from the nearest whole percent from 1990 to 2000.
Answers
Answer:
9.55%
Step-by-step explanation:
1990 = 3,69,879 2000 = 3,34,563
%Decrease = Old Value - New Value/Old Value ×100%
%Decrease = 3,69,879 - 3,34,563/369879 ×100%
%decrease = 35316/369879 × 100%
%Decrease = 9.548%
%Decrease = 9.55%(Answer)

A satellite flies 118404 miles in 15.18 hours. How long would it take to fly 174798 miles?
Answers
Answer:
22.41 hours
Step-by-step explanation:
Set up a proportion where x is the time to fly 174798 miles
[tex]\frac{118404}{15.18}[/tex] = [tex]\frac{174798}{x}[/tex]
Cross multiply and solve for x:
118404x = 2653433.64
x = 22.41
So, it would take 22.41 hours to fly 174798 miles

If the roots of the equation
lx²+nx+n=o is in the ratio p:q
then
√(p/q) + √(q/p)=?
Answers
Step-by-step explanation:
Let the given ratio be pk : qk .
So , here the quadratic equation is lx² + nx + n = 0. With respect to Standard form ax² + bx + c = 0.
We have ,
a = lb = nc = n→ Sum of roots = -b/a = -n/l = qk + pk
→ Product of roots = c/a = n/l = k²pq .
[tex]=> \dfrac{n}{l} = \dfrac{k^2}{pq} \\\\=> k^2 =\dfrac{n}{pql} [/tex]
And here pk and qk is a root of the quadratic equation ,
[tex]=> lx^2 + nx + n = 0 \\\\=> l(pk)^2 + n(pk) + n = 0\\\\=> lp^2k^2+npk + n = 0 \\\\=> lp^2\bigg( \dfrac{n}{pql} \bigg) + np\bigg(\sqrt{\dfrac{n}{pql}} \bigg) + n = 0 \\\\ => n\bigg\{\dfrac{p}{q}+\sqrt{\dfrac{np}{lq}}+1\bigg\} = 0 \\\\=> \dfrac{p}{q}+\sqrt{\dfrac{np}{lq}}+1 =0\\\\=>\sqrt{\dfrac{p}{q}} \bigg( \dfrac{q}{p}+\sqrt{\dfrac{np}{lq}}+1\bigg) = 0 \\\\=> \sqrt{\dfrac{p}{q}}+ \sqrt{\dfrac{q}{p}}+ \sqrt{\dfrac{n}{l}}=0 \\\\\boxed{\red{\bf\longmapsto \sqrt{\dfrac{p}{q}}+ \sqrt{\dfrac{q}{p}} = - \sqrt{\dfrac{n}{l}}}} [/tex]
