algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)= 50
** please help its due soon **
Answer:
x = {-4, -2}Step-by-step explanation:
To find the intersection we need to solve the system:
y = 2x + 3(x - 3)² + (y + 6)² = 50Solve by substitution, replace y with 2x + 3 in the second equation:
(x - 3)² + (2x + 3 + 6)² = 50x² - 6x + 9 + 4x² + 36x + 81 - 50 = 05x² + 30x + 40 = 0x² + 6x + 8 = 0x² + 6x + 9 = 1(x + 3)² = 1x + 3 = ± 1x = -4, x = -2Reflect across the y-axis. Fill in the new coordinates below:

[tex]\frac{8^{7} }{8^{7} }[/tex]
7 - 7 = 0
[tex]\frac{8^{7} }{8^{7} }[/tex] = [tex]8^{0}[/tex]
anything to the power of 0 is 1
[tex]8^{0}[/tex]= 1
Answer:
1
Step-by-step explanation:
Any number divided by itself equals 1 with the exception of 0 since 0/0 is undefined.
8^7 is not equal to zero, so without doing any calculations or using any other rules, we know that
8^7/8^7 = 1
We can use the rule of exponents for dividing powers.
Rule:
[tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]
Here we have a = 8, m = 7, and n = 7.
Applying the rule, we get
[tex] \dfrac{8^7}{a^7} = 8^{7 - 7} = 8^0 [/tex]
Another rule of exponents:
[tex] a^0 = 1 [/tex]
We the zero power rule now:
[tex] 8^0 = 1 [/tex]
Therefore,
[tex] \dfrac{8^7}{a^7} = 1 [/tex]

Step-by-step explanation:
1/4 of 6 feet is how many inches
Answer:
18 inches
Step-by-step explanation:
1 ft = 12 in
6 ft = ? in
Set up an equation to convert 6 feet into inches
Variable x = number of inches
1 ft/12 in = 6ft/x in
Cross multiply (feel free to ignore units for now so it doesn't get in the way of your calculations)
1 × x = 12 × 6
1x = 72
x = 72 inches
6 feet = 72 inches so replace 6 feet with 72 inches
Now let's find 1/4 of 72 inches
Set up another equation to solve
Variable y = a fourth of seventy two inches
1/4 = y/72
Cross multiply
1 × 72 = 4 × y
72 = 4y
Divide both sides by 4 to isolate variable y
72 ÷ 4 = 4y ÷ 4
18 = 1y
18 = y
Answer:
I know I already said this but
18 inches

Jivesh brought his Model B rocket on a camping trip near the top of a mountain. He wants to model how it descends down the mountain. Here, he uses the equation h = −640t^2. When has the rocket descended 1,690 centimeters? Round your answers to the nearest hundredth. After t ≈ seconds, the rocket will have descended a distance of 1,690 centimeters. The negative time (can, cannot) be used in this context.
Answer:
i. 1.63 s
ii. The negative time cannot be used in this context
Step-by-step explanation:
i. Since h = −640t² and the rocket descends 1,690 m, h = -1,690 m (since there is a drop in height).
So, h = -640t²
t² = h/-640
t = √(- h/640)
Substituting h into the equation, we have
t = √(- h/640)
t = √[-(-1,690)/640]
t = √2.640625
t = 1.625
t ≈ 1.63 s
ii. So, the negative time cannot be used in this context because, the height drop is negative.

Explanation:
Two ships are near a buoy in the open ocean. One ship is 20 km due north of the buoy, and the other ship is 13.5 km due east of the buoy.
Round the answer to the nearest tenth.
Answer:
24 km is your answer
Step-by-step explanation:
Let x be the distance between the two ships.
Hypotenuse side = x km
Adjacent side = 13.5 km
Perpendicular side = 20 km
by using Pythagoras theorem:
x²= 13.5²+ 20²=582.25
x=√ 582.25
х =24.129857024 km
Therefore, the distance between two ships to the nearest tenth place is, 24.1 km

V = π * 25 * 8
V = π * 200
V = 200π
Heather Johnson bought a new set of tires for $436.00 and a car seat for $22.85. The state tax rate is 6%, the county tax rate is 1.5%, and the city tax rate is 0.5%. What is the total purchase price?
Answer:
$495.56
Step-by-step explanation:
Tax increases the price paid for a good or service. So, the total price paid for the goods would increase by the total amount of tax
Sum of the three taxes = 6% + 1.5% + 0.5% = 8%
Total cost of items purchased = $436 + $22.85 = $485.85
Total purchase price = Total cost of items purchased x (1 + total tax)
$485.85 x (1.08) = $495.56

If f (x) = x-5 and g(x) = 4x what is the value off [g(4)]?
Step-by-step explanation:
f[g(4)]
g(x) = 4x
g(4) = 4(4)
= 16
f(x) = x-5
f[g(4)] = f(16) = 16 - 5 = 11
So, f[g(4)] = 11

What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Given:
An element with mass 630 grams decays by 18.8% per minute.
That means, 18.8% = 0.188
Here, we will use the exponential decay function.
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Here,
A₀ = 630 grams
r = 0.188
x = 7 minutes
Substituting the values to the formula,
A₇ = 630(1-0.188)⁷
A₇ = 630(0.812)⁷
A₇ = 630(0.23275134787)
A₇ = 146.633
A₇ = 146.6 grams.
Therefore, element is remaining 146.6 grams.
