PLEASE HELP ME.!!!!! I’m begging you

Anvisha [2.4K]

Answer:

see below

Step-by-step explanation:

The graph opens upward if the sign of the squared term is positive. If that sign is negative, the graph opens downward. The first three equations open upward; the last opens downward.

The line of symmetry is the value of x that makes the squared term zero. Here, that is x=5 for all equations.

y=2/3(x-5)^2: A, D

y=1/2(x-5)^2: A, D

y=3/4(x-5)^2: A, D

y=-4(x-5)^2: B, D

Sherrod and Kamar are planning to drive at most 900 miles road trip. Sherrod drives at 60 miles per hour, and Kamar at 50 miles

Allushta [10]

The inequality gives the total expected journey from the road trip, such that the time during which Sherrod and Kamar drives is known.

a. The inequality that represents the miles that Sherrod and Kamar drives is; x + y ≤ 900

b. Two possible combination of x and y are; (600, 300) and (300, 600)

Reasons:

a. The distance distance Sherrod and Kamar plan to drive ≤ 900 miles

Sherrod's speed = 60 mph

Kamar's speed = 50 mph

The distance Sherrod drives = x

The distance Kamar drives = y

a. The miles driven by Sherrod and Kamar is given by the inequality;

x + y ≤ 900

b. Two possible combinations are;

First possible combination;

Sherrod drives for 10 hours, which gives;

Distance Sherrod drives = 60 mph × 10 hour = 600 miles

Kamar drives for 900 miles - 600 miles = 300 miles

Which gives;

Sherrod drives for 600 miles and Kamar drives for 300 miles

First combination; (600, 300)

Second possible combination;

The second possible combination is Sherrod drives for 300 miles and Kamar drives for 600 miles

Second combination; (300, 600)

You buy Apple stock for $120 per share over a period of time the stock value increased at a weekly rate of 5% you sell the stock

Rainbow [258]

Answer:

8.31 weeks

Step-by-step explanation:

Given that the cost of one share of Apple stock, C=$120

Rate is the increment of the stock value, R= 5%/week=0.05 / week.

Assuming that after t week, the stock has been sold for $180.

Since the stock value increased at 5% every week, so, the interest is compounded weekly, so

$S=C\left(1+R\right)^t \\\\ \Rightarrow 180 = 120\left(1+0.05\right)^t \\\\ \Rightarrow 180 = 120\left(1.05 )^t \\\\$

$\Rightarrow \frac{180}{120}=1.05^t \\\\\Rightarrow 1.5=1.05^t$

$\Rightarrow \ln(1.5)=t \ln(1.05)$ [taking log both sides]

$\Rightarrow t=\frac {\ln(1.5)}{\ln(1.05)}=8.31$ weeks

Hence, after 8.31 weeks the stock has been sold for $180.

Find the difference. Enter your answer in simplest terms, using the slash (/) as the fraction bar.

Kitty [74]

So, difference as in subtract? so, if it is, it would be 15. if it means percent difference, it's about 60%.

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,

rjkz [21]

Answer:

$w = \frac{1}{2}(P - 24)$

$w = 153\ yards$

Step-by-step explanation:

Given

$P = 24 + 2w$

Require

Solving (a):

$P = 24 + 2w$

Subtract 24 from both sides

$P-24 = 24-24 + 2w$

$P-24 = 2w$

Divide both sides by 2

$\frac{1}{2}(P - 24) = \frac{2w}{2}$

$\frac{1}{2}(P - 24) = w$

$w = \frac{1}{2}(P - 24)$

Solving (b):

Substitute 330 for P un the expression in (1)

$w = \frac{1}{2}(330 - 24)$

Evaluate the bracket

$w = \frac{1}{2}(306)$

$w = 153\ yards$

Question c; seem irrelevant
