Answer:

Here u go:

1. A = -1

H = 0

K = 3

Vertex = (0, 3)

Axis of symmetry: x = 0

2. A = 1

H = -2

K = -5

Vertex = (-2, -5)

Axis of symmetry: x = -2

3. A = 3

H = 1

K = 2

Vertex = (1, 2)

Axis of symmetry: x = 1

In triangle STU, u2 = s2 + t2.
sineoko [7]

Answer:

(B) The measure of angle SUT is equal to 90 degrees

Step-by-step explanation:

It is given that in In triangle STU, u^2=s^2+t^2.

We can see from the triangle and also the given condition that the triangle will be right triangle as it is satisfying the Pythagoras theorem.

(Hyp)^2=(Base)^2+(Perpendicular)^2

that is:

u^{2}=s^{2}+t^{2}

where u is the hypotenuse, s is the base and t is the perpendicular.

Thus, the angle SUT should be of 90°.

Thus, The measure of angle SUT is equal to 90 degrees.

Hence, option B is correct.

What is -27/25x-9/5 pls help me
morpeh [17]
-\dfrac{27}{25}x-\dfrac{9}{5}=-\dfrac{27}{25}x-\dfrac{9\cdot5}{5\cdot5}=-\dfrac{27}{25}x-\dfrac{45}{25}=\dfrac{-27-45}{25}\\\\=-\dfrac{72}{25}=\boxed{-2\dfrac{22}{25}}

Inverse functions are defined as relationships that undo each other mathematically
BabaBlast [244]

Answer:

Inverse of exponential functions are logarithmic functions.

Step-by-step explanation:

Inverse functions exhibit a relationship where they undo each other mathematically. In this case, the inverse of an exponential function is a log function, where;

An exponential function y=a^x  has its inverse as x=a^y

This exponential equation x=a^y is equivalent to the function y= logₐ x  under the conditions; x=a^y : a>0 , a≠1

map of a city uses the scale 1 cm equals 50 m. On the​ map, South Street is 25 cm long. If there is a traffic cone at the start
aivan3 [116]

Answer:

125 traffic cones

Step-by-step explanation:

In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:

\frac{centimeters}{meters}=\frac{1}{50}=\frac{25}{x}, where 'x' is the number of meters

cross-multiply: x = 25(50) or x = 1250 m

Since there is a cone every 10 m, we can divide the total number of meters by 10:

1250/10 = 125 cones
