show all steps solving this 2x^2=13x+7
Answer:
x = -1/2, 7
Step-by-step explanation:
2x^2 = 13x + 7
bring everything to one side: 2x^2 - 13x - 7 = 0
factor it out: 2x1 = 2 and -7x1 = -7.
-7x2 = -14 and 1x1 = 1
-14 + 1 = -13, so these numbers work
you end up with (2x + 1)(x - 7) = 0
solve each section:
2x + 1 = 0 x - 7 = 0
2x = -1 x = 7
x = -1/2

There are 6500 people in a certain area. The area is growing at a rate of 3.5%.
Use the formula A=Pertto calculate the time it would take for the area to reach 11500 people. Calculate the solution for t to the nearest tenth using logarithms.
(no multiple choice)
Answer:
16.6Step-by-step explanation:
Initial number = 6500Growth rate = 3.5% = 0.035 timesFinal number = 11500Time t = ?Formula:
P(t) = 6500(1 + 0.035)^tSolve for t:
11500 = 6500*1.035^t11500/6500 = 1.035^tlog 1.7692 = log 1.035^tt = log 1.7692 / log 1.035t = 16.6 (rounded)A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below:

I want to build a shed that is 16‘ x 20‘ while I am measuring the foundation I measure the diagonal from one born to another measurement is 29 feet is the corner 90°?
Answer:
the corner is not 90 degrees
Step-by-step explanation:
To confirm if the corner is 90 degrees, we would use Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
16² + 20² =
256 + 400 =656
find the square root of 656
= 25.6 feet
If the corner was 90 degrees the diagonal should be 25.6 feet and not 29 feet

Please help me for my homework
Answer:
m<CAO = 56
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,
(m<DOA) + (m<CAO) = 180
Substitute,
3x + 40 + 2x = 180
Simplify,
5x + 40 = 180
Inverse operations,
5x + 40 = 180
-40 -40
5x = 140
/5 /5
x = 28
Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.
<CAO = (2x)
= 2(28)
= 56
What conclusion can be made for c and e? Triangle ABC has side AB measuring c, side BC measuring 4 units, and angle ACB measuring 36 and a half degrees. Triangle ABC is connected to triangle ACD by shared side AC. Triangle ACD has side AD measuring e and angle ACD measuring 27 and 8 tenths degrees. Segments BC, AC, and DC are marked congruent. c ≥ e c ≤ e c > e c < e

K
a. MJK 101°
b. JK = 799
C.
JK = 140.5°
JK = 50.5°
d.
Answer:
a) 101°
Step-by-step explanation:
arc HK = 2(39.59°) = 79.18°
arc JH = 180°
arc JK = 360° - 180° - 79.18° = 100.82°
JK = 101°
The correct answer is option (A) 101°
What is an inscribed angle?"It is an angle in a circle formed by two chords that have a common end point on the circle."
For given example,
m ∠J = 39.59°
We know, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
⇒ m(∠J) = (1/2) × arc KH
⇒ arc KH = 2 × 39.59°
⇒ arc KH = 79.18°
Also, arc HJ = 180°
We know for given figure,
⇒ arc JK + arc KH +arc HJ = 360°
⇒ arc JK + 79.18° + 180° = 360°
⇒ arc JK + 259.18° = 360°
⇒ arc JK = 100.82°
⇒ mJK ≈ 101°
Therefore, mJK = 101°
The correct answer is option (A) 101°

Answer:
y=3x+3
Step-by-step explanation:
Let's solve for y.
2y−6=6x
Step 1: Add 6 to both sides.
2y−6+6=6x+6
2y=6x+6
Step 2: Divide both sides by 2.
2y /2 = 6x+6 /2
y=3x+3

y= -5x +10
y= -2x-2
solve by substituions
Answer:
x = 4, y = -10
Step-by-step explanation:
if both expressions equal 'y' then you can solve by setting them equal to each other:
-5x + 10 = -2x - 2
-3x + 10 = -2
-3x = -12
x = 4
find 'y':
y = -5(4)+10
y = -20 + 10
y = -10

The population of rabbits on an island is growing exponentially. In the year 2000, the
population of rabbits was 220, and by 2004 the population had grown to 350. Predict
the population of rabbits in the year 2011, to the nearest whole number.
Answer:
Step-by-step explanation:
630
Answer:
789 to nearest whole number.
Step-by-step explanation:
In 4 years its increased from 220 to 350.
350 = 220(e)^4k where k is some constant.
e^4k = 350/220
4k = ln (350/220) = 0.4643
k = 0.1161
The equation of growth is therefore
P = 220e^0.1161t)
So in 2011 ( t = 11 years) the
Population = 220 * e^(11*0.1161)
= 789.
