Answer 1

Answer:

Answer:

x=5,−4

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

A circular logo is enlarged to fit the lid of a jar. The new diameter is 50 per cent larger than the original. By what percentage has the area of the logo increased?a. 50
b. 80
c. 100
d. 125
e. 250

Answers

It is easier to show th anser using fractions.

Do=original diameter
Ao=Original area
Df=Final diameter
Af=Final area

Df=(1+50%)Do=(1+1/2)Do=3/2*Do

Ao=pi/4*(Do)^2
Af=pi/4*(Df)^2=pi/4*(3/2*Do)^2=pi/4*9/...

Comparing the initial and final area:

Af/Ao=(pi/4*9/4*(Do)^2)/(pi/4*(Do)^2)

simplifying

Af/Ao=9/4=225%

Therefore the increment is 9/4-1=5/4=125%

Or equivalently: 225%-100%=125%

Therefore the answer is "D."

Note: there is calculate the increment in the difference not how many times the area changed.

Mike constructed a quadrilateral POQS. He used a compass and straightedge to accurately construct line segment OS, as shown in the figure below:An angle POQ is drawn. Two similar arcs intersect OP and OQ. Two more similar arcs intersect each other at a point S and a dashed line is drawn from O to S, such that OS bisects angle POQ

Which could be the measures of angle POS and angle POQ?

Answers

Unless we were given values of the angles, there is no way to find the numerical value of the angle. However, we can establish a relationship between the measures of angles POS and POQ. Since it was stated that OP and OQ were similar arcs (had the same value), and that OS bisects angle POQ, we can conclude that the two angles (POS and QOS) created from bisecting POQ are each, exactly half the angle POQ. Therefore:

angle POS = 1/2 angle POQ

Answer:

on the test the answer is m<POS= 25; m<POQ=50

What’s the distance between (1, 7) and (-2, -4) please help

Answers

Answer:

the slope is 11/3

so distance is 130 or 11.4 in decimal form

Answer:

Exact distance = $√(130)$

Approximate distance = 11.40175

Explanation:

We'll use the distance formula

$d = √((x_1-x_2)^2+(y_1-y_2)^2)\n\nd = √((1-(-2))^2+(7-(-4))^2)\n\nd = √((1+2)^2+(7+4)^2)\n\nd = √((3)^2+(11)^2)\n\nd = √(9+121)\n\nd = √(130) \ \ \text{ ... exact distance}\n\nd \approx 11.40175 \ \ \text{ ... approximate distance}\n\n$

Starting from 300 feet away, a car drives toward you. It then passes by you at a speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds is given by the equation d=|300−48t|. At what times is the car 60 feet from you?

Answers

The answer to this question would be: 5 second

In this question, you are given the initial distance (300ft), car velocity(48ft/s) and the final distance(60ft). You are also given the equation to calculating the distance, so this question should be easier. The question is when the time where the distance is 60 ft. So the answer would be:

distance= 300-48t

60 = 300ft- 48t

48t= 300- 60=240

t= 5
