Given the function f (x) = x² + 5, evaluate f (-10)
Answer:
f(-10)=105
Step-by-step explanation:
When something says f(x), the (x) is your plugin value. So basically in this scenario, x= -10
1) f(-10)= (-10)^2+5
2)f(-10)= 100+5
3) f(-10)= 100+5
Ok hopefully I remembered my properties of exponents correctly, but I'm pretty sure that's the answer. If it isn't, you should try making the 100 negative instead of positive from step 2 and work from there.
A store buys an item for $94. The store then prices the item to sell to customers. What is the selling price (in dollars) the store sells the item to customers for after applying a 62% markup? If necessary, round the answer to the closest hundredth.
Answer:
$152.28
Step-by-step explanation:
In order to determine the markup, multiply the original price by 62%
94 x 62% = 94 x .62 = 58.28
In order to determine the sale price, add the markup to the original price.
94 + 58.28 = $152.28
There is a number such that 7 times the number minus 15 is equal to 41
Answer: 6.571
Step-by-step explanation: If you want the exact answer, it’s 6.57142857
Answer:
8 is the number
Step-by-step explanation:
So in order to find out the "number" we are going to have to turn the equation around. First of all the equation says "minus 15 is equal to 41" so we are going to add 15 to 41:
41 + 15 = 56
So now we are going to divide 7 from 56 because we are doing the equation backwards:
56/7 = 8
So now we check our work by replacing the number in the sentence with eight, "7 times 8 minus 15 is equal to 41" which would make the equation look like this:
7 * 8 + 15 = 41
First we multiply 7 by 8:
7 * 8 = 56
Now we subtract 15 from 56:
56 - 15 = 41
Making the equation look like this:
41 = 41

john drops a probe into a lake. the elevation of the probe changes by -1 1/2 feet every second. the probe takes 50 seconds to reach the bottom of the lake. how deep is the lake show your work
Answer:
The lake is 75 ft deep
Step-by-step explanation:
Here , we want to get the depth of the lake
mathematically, we can have this as the rate at which the elevation of the probe changes multiplied by the time it took the probe to reach the bottom of the lake
That would be;
3/2 * 50 = 75 feet

Answer:
1) C=80°
2) A=C= 54°
Step-by-step explanation:
1) 180-60-40=80
2)180-72=108
108/2=54
Hope this helps! :)
Answer:
1. 80º
2. Both are 54º
Step-by-step explanation:
1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º
2. Just like in the first one, we need this to equal 180º. So, let's go backwards.
180 - 72 = 108
Now, since the remaining angles are equal, let's divide 108º by 2
108 / 2 = 54º

Coach leonardo used 9 1/2 meters of string to mark a soccer field for a game. He also used 2 2/5 meters of string to mark a spot where coaches and players will be standing during the game. Which expression could be used to determine the amount of string in meters, coach lenore i used altogether
Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or
T= 119/10 meters
or
T= 10 19/10 meters

A.game 1 (200 points per hit)
B. Game 2 (points double on each hit)
C. It depends
Answer:
C, For up to 11 hits, Game 1 gives the player higher scores. But for 12 or more hits, Game 2 does. That's because exponential growth eventually exceeds linear growth.

What are similar triangles?Similar triangle are those which have two pairs of interior corresponding angles are equal.
We have,
Two triangles as shown in the given figure,
Now,
Both the given triangles have 90° corresponding angles and also the opposite angle of 90° of both triangles is equal.
So,
Using triangle similarity rule,
i.e.
Sides are in equal proportion,
i.e.
[tex]\frac{49}{x} =\frac{14}{2}[/tex]
⇒
14x = 49 × 2
14x = 98
[tex]x=\frac{98}{14}[/tex]
x = 7
Hence, we can say that the value of x in the given diagram will be 7.

Max makes a scale drawing of the distance between Salt Lake City and Arizona. The distance between Salt Lake City and Arizona is 21 cm on the scale drawing. If each 7cm on the scale drawing equals 250 kilometers, how far apart are they actually?
Answer:
Actual distance = 750 km
Step-by-step explanation:
Given:
Scale drawing of distance = 21 cm
Scale ; 7 cm = 250 km
Find:
Actual distance
Computation:
Actual distance = 21[250/7]
Actual distance = 3[250]

You can represent the measures of an angle and its complement as tº and (90 – x)". Similarly, you can represent the measures of an angle and its supplement as x° and (180 – x)". Use these expressions to find the measures of the angles described.
1. The measure of an angle is three times the measure of its supplement.
2. The measure of the supplement of an angle is three times the measure of its complement.
3. The measure of an angle increased by 20° is equal to the measure of its complement.
Answer:
180° - t = 5 · ( 90° - t )
180° - t = 450° - 5 t
5 t - t = 450° - 180°
4 t = 270°
t = 270° : 4
t = 67.5°
The measure of an angle is 67.5°.
Its complement angle: 22.5°.
Its supplement angle: 112.5°
112.5° = 5 x 22.5°

Answer:
y = 18
Step-by-step explanation:
3.23(y – 18) - 19.17 = -19.17

On a softball field, home plate is 43 feet from the pitcher’s mound. A ball is hit at an angle of 27° east of the pitcher’s mound. The ball travels 162 feet before it is caught by an outfielder.
A triangle is drawn on a baseball field. A point is at home plate, another point is at the pitcher apostrophe s mound, and another point is at an outfielder. The distance from home plate to the pitcher is 43 feet. The distance from home plate to the outfielder is 162 feet. The angle between the 2 sides is 27 degrees.
Law of cosines:
How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot.
112 feet
125 feet
145 feet
156 feet
Answer: The answer is 125ft
Step-by-step explanation: I just did it
The law of cosines formula gives the square of the distance the
outfielder must throw the ball.
Correct response:
The distance the outfielder must throw the ball to return it to the pitcher is approximately 125 feet.How to use the cosine rule to find the distanceDistance of the home plate from the pitcher's mound = 43 feet
Angle at which the ball is hit = 27° east of the pitcher's mound
Distance the ball travels before it is caught = 162 feet
The sides, b and c, and the included angle, A, of the triangle drawn are respectively;
b = 43 feet
c = 162 feet
A = 27°
The length of the third side, a of the triangle is the distance from the outfielder to the pitcher.
According to law of cosines, we have;
a² = b² + c² - 2·b·c·cos(A)
a² = 43² + 162² - 2 × 43 × 162 × cos(27°) ≈ 15679.497105
Approximating to the nearest foot, we get;
a ≈ 125 feet
The distance the outfielder must throw the ball to return it to the pitcher is a ≈ 125 feet.Learn more about the law of cosines here:
