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°

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]

Step-by-step explanation:

Let L = length and W = Width

The problem says L = 2W

and

Area = LW = 21

Substitute

Answer:

(x - 8)² + (y - 4)² = 9

Step-by-step explanation:

(x - 8)² + (y - 4)² = 3²

(x - 8)² + (y - 4)² = 9

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

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

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.

Step-by-step explanation:

I'm guessing you are wanting to expand the expression?

[tex](7+x)^2=(7+x)(7+x)=(7)(7)+(7)(x)+(x)(7)+(x)(x)=49+7x+7x+x^2=x^2+14x+49[/tex]

Answer:

I have answered this question already.

Step-by-step explanation:

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.

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:

1/8 for each

Step-by-step explanation:

4 decided by 2 for each one

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
