beks73 [17]3 years ago
3 0

Answer:

21

Step-by-step explanation:

The remainder on dividing f(x) by (x + h) is f(- h)

Given

f(x) = - x³ - x² + 3 , then

f(- 3) = - (- 3)³ - (- 3)² + 3 = - (- 27) - (9) + 3 = 27 - 9 + 3 = 21 ← remainder

Lilit [14]

Answer:

Total number of wreaths = 3.5 wreaths

Step-by-step explanation:

Given:

Number of medium wreaths = x

Number of larger wreaths = 2[Number of medium wreaths]

Number of small wreaths = [1/2][Number of medium wreaths]

Find:

Total number of wreaths

Computation:

Total number of wreaths = Number of medium wreaths + Number of large wreaths + Number of small wreaths

Total number of wreaths = Number of medium wreaths + 2[Number of medium wreaths] + [1/2][Number of medium wreaths]

Total number of wreaths = x + 2x + 0.5x

Total number of wreaths = 3.5 wreaths

The contingency table below gives the counts of students by activities and gender. Band Sports Debate Total Male 105 320 7 432 F
Ber [7]

Answer:

599/711

Step-by-step explanation:

           Band Sports Debate Total

Male     105 320  7         432

Female 105 160         14         279

Total 210 480          21          711


P(female or plays sports)

We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them

 P(female) + P (sports) - (female and sports)

female/total + sports/total - female sports/ total

279/711 + 480/711 - 160/711

599/711

Can somebody teach what quadratic function is?
morpeh [17]
A quadratic function is one of the form f(X)=ax^2+bx +c,where a,b and c are numbers with 'a' not equal to zero.
The graph of a quadratic function is a curve called a parabola. Parabola may open upward or downward and vary in 'width' or 'steepness' , but all have the basic "U" shape.
All parabolas are symmetric with respect to a line called the axis of symmetry. A parabola intersects its axis of symmetry at a point called the vertex of the parabola.
You know that the two points determine a line. This means that if you are given any two points in the plane,then there is one and only one line that contains both points.
