Answer:
[tex]y = - 2x - 7[/tex]
Step-by-step explanation:
One way is to differentiate the function
[tex] \frac{d}{dx} {x}^{2} - \frac{d}{dx} 6[/tex]
Use Power Rule
[tex]2x - 0[/tex]
[tex]2x[/tex]
P
[tex] - 2[/tex]
Plug in -1 so we get
That gives us the slope of the tangent line. we must find the point it passes through.
[tex]( - 1) {}^{2} - 6 = - 5[/tex]
So it have a slope of -2 and passes through (-1,-5)
So we use point slope form
[tex]y + 5 = - 2(x + 1)[/tex]
[tex]y = - 2x - 7[/tex]
Leo practices piano for a
minimum of 90 minutes each
week. On Monday, he
practiced 10 minutes. For the
rest of the week, he practiced
in 20-minute sessions. How
many sessions would it take to
meet his goal?
Answer:
4 sessions.
Step-by-step explanation:
He starts with 10 minutes practiced and has to finish his quota in 20 minute sessions, so we can represent that with the equation 90=20x+10. Then solve for x.
90=20x+10
Subtract 10
80=20x
Divide by 20
x=4
It would take 4 sessions.
Answer:
1 10 min session + x 20 min sessions = 90 min
10+20x=90
20x=80
x=4 sessions

please help me please and thank you!!!!!!!!
Answer:
32° + (x+9)° + (2x-8)° = 90°
32° + x + 9° + 2x - 8° = 90°
33° + 3x = 90°
3x = 90° - 33°
3x = 57°
x = 19°
angleCFD = 2×19 - 8
angle CFD = 30°

f(n+1)=5f(n), where f(1)=3 and n>1
Answer:
[tex]f(n) = \frac35 5^n[/tex]
Step-by-step explanation:
Let's assume the solution is of the form [tex]f(n) = \alpha k^n[/tex], where [tex]\alpha[/tex] is to be determined on the starting condition, and [tex]k \in \mathbb{R} \ne 0[/tex]
[tex]f(n+1) -5f(n) = 0\\\alpha k^{n+1} -5 \alpha k^n=0\\\alpha k^n (k-5) = 0 \rightarrow k= 5[/tex]
at this point we can use our starting condition to determine the value of [tex]\alpha[/tex]:
[tex]f(1)=3 \rightarrow \alpha 5^1 =3 \rightarrow \alpha =\frac 35[/tex]
Our solution is, thus [tex]f(n) = \frac35 5^n[/tex]

Using the following data, calculate the median.
22, 22, 18, 18
Answer:
20
Step-by-step explanation:
To find the median, first, arrange the numbers from smallest to greatest. We have 18, 18, 22, 22. Next, find the number in the center. In this case, there are two numbers in the middle and it doesn't easily fall under one number. In this case, find the average of the two numbers. We have (18+22)/2 = 20. Therefore, the median of 18, 18, 22, 22 is 20.

Ants have 6 legs. Katie and Lukas write equations showing the proportional relationship between the number of ants, a, and the number of ant legs, l.
Katie writes a = 6 • 1 and Lukas writes a = 1/6 • l.
Whose equation do you agree with?
A. Katie
B. Lukas
C. Both
D. Neither
Explain your reasoning.
Answer:
A
Step-by-step explanation:
I agree with Katie because number is legs is directly proportional to the number of ants.
1 ant has 6 legs.
So, 2 ants have 6 *2 = 12
3 ants have 6*3 = 18

A circle with center O has a diameter of 26 cm. A chord, PQ, is 24 cm in length. How far is the chord from the center of the circle?
The chords from the center of the circle will be 5 cm. Apply pythogorous to find the distance of chords from the center of the circle.
What exactly is a circle?It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.
Given data;
Diameter,d=26 cm
Chord, PQ, = 24 cm
P is the chord from the center of the circle
All the given dimensions shown in the digrame are in the centimeter.
The chords from the center of the circle are found by the pythogorous theorem;
From Δ DCB
The value of the side p is;
h²=p²+b²
13²=p²+12²
169=p²+144
p=5 cm
Hence, the chords from the center of the circle will be 5 cm.

Answer:
33
Step-by-step explanation:
Using the Intersecting Chords Theorem
For any two Intersecting Chords ---> UC*CW=TC*CV
By Substituting ---> 12(2x+5)=14(2x+2)
By Expanding ---> 24x+60=28x+28
Then --> 28x-24x=60-28
Then --> 4x=32
So x=32/4=8
Now to get UW,, UW=UC+CW=12+(2x+5)=2x+17
By Substituting by x=8
UW=2x+17=2*8+17=33
