Tim says 1/8 of this model is shaded. Lucy says 8/8 of this model is shaded.
Answers
Answer:
Step-by-step explanation: Lucy is correct because all of the squares are filled, and therefore instead of 1 square filled, 8 are, this is why lucy is correct :)
Answer:
Lucy is correct.
Step-by-step explanation:
We can see that the ENTIRE model is shaded ( all eight squares).
So Lucy is correct since she stated that 8 out of 8 (8/8) squares are shaded.
8/8 = 1, so whole.
1/8 would mean that only one out of eight squares is shaded, so Tim is NOT coorrect.

Answers
Answer:
A
Step-by-step explanation:
we can find out by writing its equation;
9-(-3) / (14-4) = 12 / 10 = 6 / 5
so its equation gonna be y = 6/5x - 7.8
.
now we can grid in the answer choices:
-9 = -6/5 -7.8 so (-1 , -9) is the correct answer
.
First what you can do is find the eq of the line where you need the slope(m) and a point on the line
To find slope (m)
(Y2-y1)/(x2-x1)
(4,-3)=(x1,y1)
(14,9)=(x2,y2)
(9-(-3))/(14-4)
=(9+3)/10
=12/10
m=1.2
Sub this information into the formula
y-y1=m(x-x1)
y-(-3)=1.2(x-4)
y+3= 1.2x -4.8
y=1.2x -7.8
Now sub each point a - d into this to see if they are true
y=1.2x -7.8
a.(-1,-9)
-9=1.2(-1)-7.8
-9=-1.2-7.8
-9=-9
TRUE -POINT IS ON LINE
b.(-2,-8)
-8=1.2(-2)-7.8
-8=-2.3-7.8
-8=-10.1
NOT TRUE -POINT ISNT ON LINE
c.(29,27)
27=1.2(29)-7.8
27=34.8-7.8
27=27
TRUE -POINT IS ON LINE
d.(28,18)
18=1.2(28)-7.8
18=33.6-7.8
18=25.8
NOT TRUE -POINT ISNT ON LINE

What is the area of the square? A square with the left side labeled 4 units.
Answers
4^2 = 16
the area is 16 units
Answer:
Area = 16 units
Step-by-step explanation:
Area = length * width Length = x Width = w
A = (x) (w)
Because the shape is a square we know all 4 sides are equal, the lenth and width are the same sizes.
x = 4 units
w = 4 units
A = 4*4
A= 16 units

The area of the second circle larger than the area of the first circle will be 63.585 square inches.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the diameter of the circle. Then the area of the circle will be
A = (π/4) d² square units
The width of one circle is 12 inches long. The width of a subsequent circle is 25% longer than the measurement of the primary circle.
The diameter of the second circle is given as,
⇒ 1.25 x 12
⇒ 15 inches
The area of the first circle is given as,
A₁ = (π/4) (12)²
A₁ = 113.04 square inches
The area of the second circle is given as,
A₂ = (π/4) (15)²
A₂ = 176.625 square inches
The area of the second circle larger the area of the first circler is given as,
A = A₂ - A₁
A = 176.625 - 113.04
A = 63.585 square inches
The area of the second circle larger than the area of the first circle will be 63.585 square inches.

Answer:
A=467.61 ft^2
Step-by-step explanation:
This is a trapezoid. The area of this trapezoid is [tex]A=\frac{1}{2}(25+33)h[/tex] . 33-25 is 8, so that is the base of the little traingle if we break up the slanted end into a triangle. Now we can use the pythagoreum theorem to find out that the height is 16.125 .
Now the Area equation is [tex]A=\frac{1}{2}(25+33)16.125[/tex]
That gives us our final answer of 467.61 ft^2
When driving in England, Brian drove through several speed cameras. On one drive, Brian left his hotel and after 7 minutes he was 2.5 km away and at that moment was measured going 0.5 kpm (kilometers per minute). Later, 18 minutes after he started driving, he was 14.8 km from the hotel and at that moment was measured going 0.8 kpm.
A. Find the linearization at 7 minutes.
B. Find the linearization at 18 minutes.
C. Compute two approximations for Brian's distance from his hotel at 14 minutes, using the linearizations from parts a and b.
D. Which approximation do you think is better? Why?
Answers
Solution :
The formula for the linearization of a function [tex]$f(x)$[/tex] at a point [tex]$x$[/tex] = a is given as
[tex]$L(x)=f(a)+(x-a)f'(a)$[/tex]
Assuming the time is t and the distance travelled is [tex]$f(t)$[/tex], that makes the speed as [tex]$f'(t)$[/tex].
So substituting them in the linearization formula,
A. At t = 7 minutes
f(7) = 2.5 km
f'(7) = 0.5 kpm
∴ [tex]$L_7(t)=f(7)+(t-7)f'(7)$[/tex]
[tex]$=2.5+(t-7)0.5$[/tex]
[tex]$=2.5+0.5t-3.5$[/tex]
[tex]$=0.5t-1$[/tex]
B. At t = 18 minutes
f(18) = 14.8 km
f'(18) = 0.8 kpm
∴ [tex]$L_{18}(t)=f(18)+(t-18)f'(18)$[/tex]
[tex]$=14.8+(t-18)0.8$[/tex]
[tex]$=14.8+0.8t-14.4$[/tex]
[tex]$=0.8t-0.4$[/tex]
C. Substituting the value of t as 14 in both the linearization to determine the position at 14 minutes, we get
[tex]$L_7(14)=0.5(14)-1.0$[/tex]
= 7 - 1
= 6 km
[tex]$L_{18}(14)=0.8(14)+0.4$[/tex]
= 11.2 + 0.4
= 11.6 km
D. According to the linearization at 7, the distance travelled between the 7 minutes and 14 minutes is = 6 km - 2.5 km
= 3.5 km
And between the 14 minutes and 18 minutes is = 14.8 km - 6 km
= 8.8 km
This is an average speed of 0.5 kpm in the first interval and an average speed of 2.2 kpm.
Now, according to the linearization of 18, the distance travelled between the 7 minutes and the 14 minutes is = 11.6 km - 2.5 km
= 9.1 km
And between 14 minutes and 18 minutes is = 14.8 km - 11.6 km
= 3.2 km
This gives an average speed of 1.3 kpm in the first interval and 0.8 kpm in the second interval.
Therefore, the second approximation is the better one since the average speed are closer to the actual readings in the second linearization.

Reference angle = <A
Opposite side to <A = 6
Adjacent side = 8
Hypotenuse = AB = √(8² + 6²) = 10 (pythagorean theorem)

✔️Sin A = Opp/Hyp
Sin A = 6/10 = 3/5
✔️Cos A = Adj/Hyp
Cos A = 8/10 = 4/5
