What is the formula for a vertical shrink?
The y-values are multiplied by a value between 0 and 1, which causes them to travel in the direction of the x-axis. This is known as a vertical shrink and tends to flatten the graph. A point (a,b) on the graph of y=f(x) y = f (x) shifts to a point (a,kb) (a, k b) on the graph of y=kf(x) y = k f (x) in both scenarios.
Describe the transformation of the parent graph
f(x)=x^2 represented by g.
g(x)= -(2x+3)^2 - 5
Graph represents ( - 1.5 , -5 )

The value of x from the given expression is 10
Solving linear expressionsLinear function are functions that has a leading degrees of 1. Given the expression below;
(8x+10)=(6x+30)
Collect the like terms
8x - 6x = 30 - 10
2x = 20
Divide both sides by 2

Malia and some of her friends are going rock climbing this weekend. In preparation, Malia purchased 8 sports drinks to bring, including 6 peach flavored drinks.
If Malia randomly chooses to place 4 drinks in the red cooler, what is the probability that all of them are peach flavored?
Write your answer as a decimal rounded to four decimal places.
Based on the fact that there are 8 sports drinks and 6 peach flavored drinks, the probability that all 4 drinks picked by Malia would be peach flavored is 0.2143.
What is the probability?The probability that all 4 drinks will be peach flavored can be found as:
= Probability of first drink being peach x Probability of second drink being peach + Probability of third drink being peach + Probability of fourth drink being peach
The probability of the drinks being peach flavored is:
= 6/8 x 5/7 x 4/6 x 3/5
= 0.2143
In conclusion, the probability that all the drinks are peach flavored is 0.2143.

Answer:

step-by-step explanation:(vertically opposite angles)

3x-56=x+2
group like terms
3x-x=56+2
2x=58
divide both side by the coefficient of x
2x/2=58/2
x=29
<RIG+<GIM=90°
4z+7+x+2=90°
where x=29
4z+7+29+2=90°
4z+38=90°
make for 4z the subject
4z=90°-38°
4z=52°
let z stand alone

z=13
<RIG=4z+7
where z=13
4(13)+7
52°=RIGZ
<ZIM=x+2
where x =39+2
x=31°
Answer:
x = 29
z = 13
Angle RIG = 59 deg.
Angle ZIM = 41 deg.
Step-by-step explanation:
So we know that angle ZIA = angle MIG
3x - 56 = x + 2
We can solve this equation
2x = 58
x = 29
Next, angle RIG + GIM = 90 degrees.
So if we do 4z + 7 + x + 2 = 90 degrees when x = 29, we can plug x in.
4z + 7 + 29 + 2 = 90 degrees
4z + 38 = 90 degrees
4z = 90 - 38
4z = 52
z = 13
Angle RIG = 4z + 7
We know that z = 13
4 * 13 + 7 = 52
Therefore RIGZ = 52 degrees.
Angle ZIM = x + 2
x = 39 + 2
x = 41

if the sides in a parallelogram are 3 cm and 5 cm, can the diagonal in the parallelogram be 10 cm? 8 cm? 4 cm? why?
The diagonal of the parallelogram be 10 cm or 8 cm.
What is defined as the parallelogram?A parallelogram is just a quadrilateral with two parallel sides (and therefore opposite angles equal).
A rhombus is a quadrilateral to equal sides, while a rectangle is a parallelogram with all right angles. Furthermore, because a square is a degenerate situation of a rectangle, rectangles and squares are both special kinds of parallelograms.A parallelogram's opposite sides are all the same length.A parallelogram's adjacent or adjoining angles add up to 180°.A parallelogram's diagonals cross each other.For the given case.
The sides of the 3 cm and 5 cm. As, these two side are the adjacent sides of the parallelogram, the diagonal formed will be the closing side of the triangle.
As, the diagonal is the longest side of the triangle, thus its value must be greater than other side.
This is possible with the diagonal values of 10 cm and 8 cm.
Thus, 10 cm and 8 cm are the correct values for the diagonal of parallelogram.

The power of a number tells us how many times that number must be multiplied. Exponents and indexes are other names for powers. For instance, 8² denotes "8 squared," "8 squared," or just "8 squared."
A power is just an expression that denotes repeatedly multiplying the same number or factor. The exponent value depends on how frequently the base has been multiplied by itself.
For instance, 8 x 8 x 8 x 8... times is 8. The phrase 8n above is pronounced as 8 raised to the power n. As a result, exponents are also sometimes referred to as power or indices.

If FG = 2x, GH = x-1, and FH = 5 what is GH?
Answer:
GH = 1
Step-by-step explanation:
Finding the value of x,
→ FG + GH = FH
→ 2x + x - 1 = 5
→ 3x = 5 + 1
→ x = 6/3
→ [ x = 2 ]
Now the value of GH is,
→ GH = x - 1
→ GH = 2 - 1
→ [ GH = 1 ]
Hence, the value is 1.

What is proof by contraposition?Proof by contrapositive, also known as proof by contraposition, is an inference technique used in mathematics where a conditional statement's contrapositive is used to infer the conditional statement's conclusion. To put it another way, the conclusion "if A, then B" is inferred by building a proof of the claim "if not B, then not A" instead. This method is frequently chosen if the contrapositive is more straightforward to establish than the first conditional statement.
The term "contraposition" describes a proving strategy known as "proof by contraposition," which involves drawing an inference from a conditional statement to its logically equivalent contrapositive. The antecedent and consequent of a sentence are inverted and flipped in the contrapositive.

The distance is
(Type an exact answer, using radicals as needed.)
The distance between the given two points is 25.
The coordinates of two points given to us are (-9, 9) and (-16, 33).The length of the line segment connecting two places is defined as the distance between them. The length of the line segment connecting the specified coordinates can be used to compute the distance between two locations in coordinate geometry.The distance (d) between the two points whose coordinates are (x1, y1) and (x2, y2) is given by the formula:d² = (x2-x1)² + (y2-y1)² We will apply the above formula.d² = (-16-(-9))² + (33-9)²d² = (-16 + 9)² + (33-9)²d² = (-7)² + (24)²d² = 49 + 576d² = 625d = √625d = 25Thus, the distance between the given points is 25.To learn more about distance, visit :
