Answer:

7) B.

8) D.

Step-by-step explanation:

Trucks will be able to pass through tunnel B while tunnel A is destroyed.In light of this, the equations for tunnels A and B are x2 + y2 + 30x + 56 = 0 and x2 - 30x + 16y - 95 = 0, respectively.

A parabola's general equation is either y = a(x-h)2 + k or x = a(y-k)2 + h, where (h, k) stands for the vertex.

y2==4ax is the typical equation for a normal parabola.

Section A: x2+y2+30x+56=0

On both sides of an equation, add 152.

This is,

x²+30x+15²+y²=-56+15²

⇒ (x+15)²+y²=169⇒ (x+15)²+y²=13²

On both sides of the equation, divide 132.

⇒ (x+15)²/13² + y²/13² =1

Part B:x²-30x+16y-95=0

x2-30x+16y=95 now,

On both sides of an equation, add 152.

In other words, x2-30x+152+16y=95+152

⇒ (x-15)²=320-16y

⇒ (x-15)²=16(20-y) (20-y)

Part C:greatest height:A: 13 feet

B: 20 feet ,8 feet wide

A: x+15=8/2=4 y=12.37<13.5

B: x-15=8/2=4 y=19>13.5

In turn, tunnel A will sustain damage while the truck can travel via tunnel B.

The missing numbers are 14 and 17. there are 50 steps taken to reach the last pebble on this part of the path.

What is the missing number?

Missing numbers are the numbers that have been missed in the given series of a number with similar differences among them.

let's take a look at pebbles along each part of the path, there is 1 number of addition to each pebble number to go on next pebble.

i.e. 12, 13, 14, 15, 16, 17

so, the missing numbers are 14 and 17.

now, as given Hansel and Gretel used a pebble to mark every 10 steps as they walked along the path. How many steps have they taken when they get to the last pebble on this part of the path?

so, to go on next pebble there are 10 steps to walk.

therefore, from starting pebble  number 12 to last pebble number 17, there are 50 steps ( difference between two pebbles is 10 steps).

The value of h(-2)+g(4) by substitution is 6

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

For instance if h(x)=3x+1 . This means h(-2) means we are going to substitute -2 for variable x

Therefore h(-2) = 3(-2)+1

= -6+1 = -5

Similarly g(x)=x²-5. This means g(4) means we are going to substitute 4 for x in the equation.

Therefore g(4) = 4²-5

= 16-5 = 11

Therefore h(-2)+g(4) = -5+11

Answer:

y = 1425 * (1 + 0.05)^x

Step-by-step explanation:

An exponential function of the form y = a * b^x can be used to model exponential growth or decay, where a is the initial value, b is the base (growth or decay factor), and x is the time period. In this case, the initial value is 1,425 and the rate of increase is 5%. We can write this as an exponential function as follows:

y = 1425 * (1 + 0.05)^x

where y is the final value after x time periods, and x is the number of time periods (in years, for example). To find the value of the function after x time periods, you can substitute the value of x into the equation.

The zeros of quadratic function 2x² - 7x + 3 = 0 are 3 and 1/2.

There are several methods for solving a quadratic equation of the form ax² + bx + c = 0. In our case, use the quadratic formula x = (-b ± √(b² - 4ac)) / 2a to find the zeros or the solutions for x.

Plug in the values to the formula and solve for x.

x = (-b ± √(b² - 4ac)) / 2a

x = (--7 ± √(-7² - 4(2)(3))) / 2(2)

x = (7 ± √49 - 24) / 4

x = (7 ± √25) / 4

A right triangle is any triangle that has a 90-degree angle.

A 30-60-90 triangle is a special type of right triangle that has a 30-degree angle and a 60-degree angle in addition to the right angle.

The side opposite the 30-degree angle is called the shorter leg.

The side opposite the 60-degree angle is called the longer leg.

The side opposite the right angle of 90 degrees is called the hypotenuse.

The hypotenuse is twice the shorter leg.

The longer leg is √3 times the shorter side.

if the length of the shorter leg is given, then these properties are used to find the longer side and the hypotenuse.

However, the 30-60-90 properties hold no matter which side is provided.

If the length of the hypotenuse is given, divide it by 2 for the shorter leg. Then multiply that result by √3 to get the length of the longer leg.

If the length of the longer leg is given, divide it by √3 to get the shorter leg. Then, multiply that result by two to get the length of the hypotenuse.

Answer:The slope of the given line is -4

Step-by-step explanation:

Knowing if your cervix is dilating typically involves a physical examination by a healthcare provider.

During labor, a healthcare provider will check the dilation of your cervix by performing a pelvic exam. They will use their fingers to feel the cervix, which is located at the top of the vagina, and determine the degree of dilation.

Cervical dilation is measured in centimeters, and full dilation is considered to be 10 centimeters. Before labor begins, the cervix is typically closed and has a firm consistency. As labor progresses, the cervix will start to soften and thin out, and will eventually open, or dilate.

Some women might experience Braxton Hicks contractions, which are sometimes referred as "false contractions" as they can be mistaken for the start of labor, but Braxton Hicks contractions do not cause cervical dilation.

It's important to note that dilation is just one of the factors that indicate that labor is imminent. It is not the only factor and some women can have a fully dilated cervix for days before going into active labor.

In conclusion, knowing if your cervix is dilating typically involves a physical examination by a healthcare provider, who will perform a pelvic exam to feel the cervix and determine the degree of dilation.

Cervical dilation is measured in centimeters, with full dilation being 10 centimeters. Be aware that dilation is just one of the factors that indicate labor is imminent.
