Answer:
y- intercept = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
f(x) = [tex]\frac{1}{2}[/tex] [tex](6)^{x}[/tex]
To find the y- intercept let x = 0 , then
f(0) = [tex]\frac{1}{2}[/tex] [tex](6)^{0}[/tex] [ [tex]6^{0}[/tex] = 1 ]
= [tex]\frac{1}{2}[/tex] × 1 = [tex]\frac{1}{2}[/tex] ← y- intercept

Which set of ordered pairs (x, y) could represent a linear function?
A = {(3,5), (5,1), (7, -2), (9,-6)}
B = {(2,-5), (5,1), (6,3), (7,6)}
C = {(-4,3), (-2,0), (0, -4), (2, –7)}
D = {(-3,7), (-1,5), (1,3), (3, 1)}
Answer = C
because all are not in set pairs only no. C is pair of set
What in a region can be affected by latitude, topography, altitude and closeness to a large body of water, jet streams and surface currents?
Answer:
Hey!
Step-by-step explanation:
Latitude, or how far one is from the equator, greatly affects the climate and weather of an area. If you live close to the equator, the climate will be warmer, while moving north or south from the equator brings a cooler climate. Altitude, or how high one is above sea level, has a similar effect–the higher the elevation, the colder the climate.

∆ has the coordinates (3, 1), (5, 2), (4, 3). ∆´´´ has coordinates (-1, 2), (1, 3) and (0, 4). Which choice describes the translation of ∆ to ∆´´? A +4 units in the direction of x and -1 units in the direction of y B -4 units in the direction of x and +1 units in the direction of y C +4 units in the direction of x and +1 units in the direction of y D -4 units in the direction of x and -1 units in the direction of y
Answer:
B -4 units in the direction of x and +1 units in the direction of y
Step-by-step explanation:
Given
[tex]A = (3, 1), (5, 2), (4, 3)[/tex]
[tex]A^{-1}= (-1, 2), (1, 3) (0, 4)[/tex]
Required
Determine the translation from A to A-1
Take (3,1) from A and (-1,2) fro A-1 as points of reference,
For translation to occur, we make use of:
[tex](3 + x,1+y) = (-1,2)[/tex]
By comparison:
[tex]3 + x = -1[/tex] and [tex]1 + y = 2[/tex]
Solve for x and y
[tex]3 + x = -1[/tex]
[tex]x = -1-3[/tex]
[tex]x = -4[/tex]
[tex]1 + y = 2[/tex]
[tex]y = 2 - 1[/tex]
[tex]y=1[/tex]

A car dealership sells sedans and SUVs. In 2000, the ratio in which they were sold was 5:4. By 2010, the dealership had adjusted its inventory to a 2:7 ratio. If it sold 84 SUVs in 2010, how many sedans did it sell in 2000?
Answer:
60 sedans
Step-by-step explanation:
The computation of the number of sedans sold in 2000 is given below:
Given that
The ratio of sedans and SUV is 5:4
And, in 2010 its ratio is 2:7
Now in 2010, 84 SUVs sold
So
84 SUVS = 7
For total 9, it would be
= 84 × 9 ÷ 7
= 108 vehicles
Now the number of sedans is
= 108 × 5 ÷ 9
= 60 sedans

Step-by-step explanation:
[tex] \sin 45 \degree = \frac{x}{8} \\ \\ x = 8 \sin 45 \degree \\ \\ x = 8 \times \frac{1}{ \sqrt{2} } \\ \\ x = \frac{8 \sqrt{2} }{2} \\ \\ x = 4 \sqrt{2} \\ \\ \\ \tan 30 \degree = \frac{x}{y} \\ \\ \frac{1}{ \sqrt{3} } = \frac{4 \sqrt{2} }{y} \\ \\ y = 4 \sqrt{6} [/tex]
