A Sketch Of Y = Ax + Bx + C Is Shown.The Maximum Point Is (-3, 4)Select The Correct Answer In Each Of

Answers

Answer 1

Answer:

A, A and A

Step-by-step explanation:

Given

y = ax² + bx + c

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here the vertex is a maximum, thus a < 0 , that is negative → A

The value of c is the y- intercept

The graph crosses the y- axis below the y- axis, thus c is negative → A

The solutions to ax² + bx + c = 0 are the values of x on the x- axis where the graph crosses the x- axis.

The graph crosses the x- axis to the left of the y- axis , thus

Both solutions are negative → A

What will be the slope of (3,-4) and (1,2)

Answers

Answer:

[tex]\boxed {m = 1}[/tex]

Step-by-step explanation:

Use the Slope Formula to determine the slope of two given points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

First Point: [tex](x_{1}, y_{1})[/tex]

Second Point: [tex](x_{2}, y_{2})[/tex]

-Substitute both points:

First Point: [tex](3, -4)[/tex]

Second Point: [tex](1, 2)[/tex]

[tex]m = \frac{2 + 4}{1 - 3}[/tex]

-Solve for the slope:

[tex]m = \frac{2 + 4}{1 - 3}[/tex]

[tex]m = \frac{-2}{-2}[/tex]

[tex]\boxed {m = 1}[/tex]

Therefore, the slope is [tex]1[/tex].

Answers

Answer:

48.76%

Step-by-step explanation:

Here is the complete question;

A brand of cereal had 1.21milligrams of iron per serving. Then they changed their recipe so they had 1.8mg of iron per serving. What was the percent increase in iron?

Given

Initial amount of iron in cereal per serving = 1.21mg

final  amount of iron in cereal per serving =1.8mg

Required

Percentage increase in iron

Increment = 1.8mg - 1.21mg

Increment = 0.59mg

% increase in iron = increment/original amount * 100%

% increase in iron = 0.59/1.21 * 100

% increase in iron = 0.4876 * 100

% increase in iron = 48.76%

Hence the percent increase in iron is 48.76%

An ice cream shop had 316 customers the first weekend it opened. The second weekend it had 468. What is the percent of increase in the number of customers? Round to the nearest percent.

Answers

Answer:

48%

Step-by-step explanation:

Given that,

No of 316 customers the first weekend it opened.

The second weekend it had 468.

We need to find the percent of increase in the number of customers.

The formula of percentage is given by :

[tex]\%=\dfrac{|\text{old number-new number}|}{\text{old number}}\times 100[/tex]

Here, old number = 316 and new number = 468

So,

[tex]\%=\dfrac{|316-468|}{316}\times 100\\\\\%=48.10\%[/tex]

or

% = 48%

So, the percent of increase in the no of customers is 48.

for x=-2,

it's the easiest one, just see if there is a vertical crossing -2 on the x-axis.

for-2x+4,

you can see it as move y=-2x up 4 units, and for y=-2x, you can find it out by sub (1,-2) and (0,0) onto the graph.

for x²-4,

see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.

A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line. Assuming that field goal attempts can be considered random events, what is the probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line?

Answers

Answer:

Step-by-step explanation:

answer should be 0.39

The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is 0.39.

What is the probability?

Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?

Given:

A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line.

Assuming that field goal attempts can be considered random events.

P = 0.85

n = 5

Standard deviation = √{5 x 0.85 x (1 - 0.85) = 0.79

The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is,

= P (X ≥ 4)

= P (X ≥ 3.5)

= 1 - P(X < 3.5)

= 0.39

Therefore, the probability is 0.39.

In the 48 years between 1842, the average rate of erosion at horseshoe falls was 33 divided by 50 metre per year. In the 22 years between 1905 and 1927 the rate of erosion was 7 divided by 10 meter per year . Approximately how much total erosion occurred during these two time periods

Answers

Answer:

47. 08 meters

Step-by-step explanation:

Given that:

In 48 years between 1842 :

Rate of erosion = 33/50 meters per year

Between 1905 - 1927 (22 years)

Rate of erosion = 7/10 meters per year

Approximately how much total erosion occurred during these two time periods ;

Total erosion that occured within 1842:

Rate of erosion * number of years

(33/50)m * 48

0.66 meters * 48

= 31.68 meters

Total erosion that occured between 1905 - 1927:

Rate of erosion * number of years

(7/10)m * 22

0.7 meters * 22

= 15.40 meters

total erosion which occurred during these two time periods ;

31.68 meters + 15.40 meters

= 47.08 meters

Answer:

47. 08 meters

Given that:

In 48 years between 1842 :

what is $4.89 x $6.3 HELP GIVING BRAINLIEST You might think that staying safe during the eruption of a volcano is just a matter of hiding under a table and hoping your house doesn't catch on fire. Nothing could be further from the truth. Surviving a volcanic eruption is a matter of understanding how volcanoes most commonly affect people, being prepared, and following some easy guidelines.Volcanic activity may be scary, but it is the result of simple and very natural geological processes. Volcanoes are holes in the Earth's crust where substances from beneath the surface, such as hot gases and molten rock, can escape. "You can think of a volcano as a paper cut or a pimple on the Earth," says volcanologist Roberta Alvarez. "They're usually not a big deal on the scale of the whole planet, but they're a big deal to us." Sometimes these eruptions can be small and ongoing, such as the Mt. Kilauea eruption in Hawaii that has been occurring since 1983. Other times, as was the case with Mt. St. Helens in Oregon, the eruptions are abrupt and violent. When the lava and ash emitted from a volcano cool and harden, they gradually form mountains.If you're wondering whether or not you live near one of these mountains, you're in luck. The U.S. Geological Survey (USGS) keeps track of active volcanoes all around the Ring of Fire, which is the area of high volcanic activity that forms the border of the Pacific Ocean. Some of the most worrisome volcanoes in the United States are Mt. Kilauea in Hawaii and Mt. Shishaldin in Alaska. The USGS records many other at-risk locations as well, so you can find out how risky your location is with just a little research.If you're one of the people who lives near a volcano, you should be aware of several dangers that these forces of nature present. The most dramatic danger is molten lava that flows down the sides of the mountains. "Although lava moves slowly enough for most people to escape from it on foot," says Alvarez, "it's a precursor to a much more dangerous threat: wildfires." Volcanoes also tend to spew huge amounts of ash into the atmosphere, which can affect areas hundreds of miles away from the eruption and can make breathing difficult for babies and people with lung problems, according to the National Asthma Society (NAS). The ash can also be so thick that it buries houses.If you live near an active volcano, your best chance of surviving an eruption is to be prepared. The Federal Emergency Management Agency, or FEMA, recommends that families maintain an emergency supply kit with first aid and day-to-day essentials. Families should also create a plan to gather in an agreed-upon location if phone or Internet service is down. Once you account for everyone in your family, follow the designated evacuation route to get away from the volcano quickly and carefully.In other words, stay calm and be prepared. Advice that would be suited to practically any disaster will help you weather a volcanic eruption as well. All you need is a little understanding, a little planning, and a little patience, and you should come out all right.Which is the best example of an analysis paragraph in the essay?A.Paragraph 3B.Paragraph 4C.Paragraph 1D.Paragraph 2 The revolutions in Latin America in the 19th century resulted ina) political independence from Europeb) the end of slavery in each countryc) the establishment of stable democraciesd) social and economic equality for all A car traveling initially at 8.46 m/s acceler-ates at the rate of 0.963 m/s2 for 5.63 s.What is its velocity at the end of the accel-eration? how do you solve 6-9(4p-3)= 2(6p+7)+3 5.
