At the skateboard park, the hot new attraction is the U-Dip, a cement structure embedded into the ground. The cross-sectional vi

ew of the U-Dip is a parabola that dips 15 feet below the ground. The width at ground level, its widest part is 40 feet across. Sketch the cross-sectional view of the U-Dip, and find an equation of the parabola that models it.

Find the equation of the line that passes through the point (-1, 2) and that has a
photoshop1234 [79]

Answer:

y = 4x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 1, 2) into the partial equation

2 = - 4 + c ⇒ c = 2 + 4 = 6

y = 4x + 6 ← equation of line

In a University of Wisconsin (UW) study about alcohol abuse among students, 100 of the 40,858 members of the student body in Mad
dimaraw [331]

Answer:

a) The population is 40,858 students and the sample is 100.

b) No

Step-by-step explanation:

a) The population would be the 40,858 members of the student body. Since we are only applying the questionnaire to 100 students, the sample would be 100.

b) 29% of the students answered "zero" to the question on how many days in the past week they consumed at least one alcoholic drink. This means that 29 out of 100 students gave this answer. However, this doesn't mean that 29% of the entire population of UW would give this response. Why is that? Because our sample is very small so it might not be representative of the whole population. Equally, the results from such a sample cannot be exactly the same results we would get from an entire population.

PLEASE help due today Geometry
irina1246 [14]

\\ \sf\Rrightarrow \dfrac{15}{20}=\dfrac{21}{28}

\\ \sf\Rrightarrow \dfrac{1}{4}=\dfrac{1}{4}

Hence they are similar

#2

  • <A=<H
  • And ratio of sides are same

Hence both triangles are similar by SAS property

#3

\\ \sf\Rrightarrow ∆KDH\sim ∆ABD

The equation of a line is given below . 6x+2y =-18 find the x intercept and the y intercept
vova2212 [387]

Answer: x intercept is -3

y intercept is -9

Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept

6x+2(0)=-18

divide both sides by 6, and get -3 as an x intercept
